  • 11/02/15--06:51: Mobile VoIP
  • Mobile VoIP is an efficient, low-cost way to communicate using your cell phone and the services provided by your home or business VoIP provider.

    How Does Mobile VoIP Work?

    Mobile VoIP works with a cell phone’s 3G, 4G, GSM, or other Internet service to send voice calls as digital signals over the Internet using voice over IP technology. Mobile VoIP phones can also take advantage of WiFi hotspots to eliminate the calling costs of a cellular voice or data plan.

    By using VoIP, mobile VoIP phone users — especially smartphone users — can benefit from lower costs when calling, texting, or other common smartphone activities. Digital data transmission using VoIP is also typically faster, as the data is spread out over multiple packets, each taking the fastest route to its intended destination.

    Using a mobile VoIP phone with WiFi hotspot access can also reduce a mobile VoIP phone user's costs by sidestepping the carrier's expensive 3G service altogether. For instance, with a cellular carrier's monthly data plan, callers can easily exceed bandwidth maximums, incurring overage charges. Tapping into WiFi hotspots with mobile VoIP software reduces that risk and extends the lifespan of the monthly data allotment.

    A mobile VoIP phone service can eliminate the need for a basic voice plan, as well as optional (and costly) text add-ons. With a mobile VoIP phone, cell phone users can enjoy more flexibility in calling times than a cellular voice plan provides, with fewer restrictions. VoIP mobile phone service means that a mobile VoIP user can make unlimited inexpensive or free calls using voice over IP technology at any time.

    Mobile VoIP users don't need to worry about the limitations associated with cell phone calling plans, such as:

    • Anytime minutes
    • Night or weekend minutes
    • Rollover minutes
    • Roaming charges
    • Incoming call charges
    • Messaging limits
    • Mobile-to-mobile calling (check with your mobile VoIP provider, some do treat in-network calls differently)

    Mobile VoIP phone users can also take advantage of the additional, integrated features a mobile VoIP app supports. This includes high-bandwidth activities such as group chat and video chat. Accessing these functions without mobile VoIP software (by fring or Talkonaut, for instance), typically requires a separate app, and using it could impact or exceed monthly text and bandwidth maximums.

    Accessing Mobile VoIP

    Cell phone users can use mobile VoIP service on their phone with the addition of mobile VoIP software. These are apps offered by VoIP phone service providers customers may already be using at home or at work, such as Vonage, or standalone mobile VoIP apps such as Skype, Vyke, or Truphone.

    Some services, such as Truphone, also offer an entire mobile VoIP network by combining a SIM (Subscriber Identity Module) card and an app together. (The SIM card contains all the information needed to identify network subscribers. ...

  • 11/02/15--20:13: SBO
  • sbo multipath logo.jpg

    What is SBO?

    Synchronous Bandwidth Optimizer is generally known as SBO. It is a bandwidth optimization solution for VoIP call termination developed by Synchronous ICT, a world famous VoIP software provider. It is a pioneer Bandwidth Optimization Technology fully loaded with amazing features.

    Why Bandwidth Saver is so important for VoIP?

    In VoIP termination, main expenditure is Bandwidth cost. Minimizing Bandwidth consumption is the main purpose of SBO Solution, at the same time it helps to reduce business operation cost. As a perfect bandwidth saver SBO reduces more than 80% internet cost directly. However, the quality of service is never compromised. To run a quality VoIP business congestion free, telco grade bandwidth connection is required . Such type of bandwidth connection is very costly as well as extremely rare. So, it was almost impossible to run quality VoIP business basically for small and medium entrepreneurs. But, now things are different, SBO Multipath make its possible to run IP telephony business with low cost share internet connection by maintaining supreme service quality. It can combine multiple internet connections together and use all the available bandwidth creating a single connection.

    How does SBO work?

    Well, there are mainly two parts in SIP communication, one is payload and another is RTP header. For a SIP call with G.729 it consumes almost 31.5 kbps bandwidth. But, noticeable matter is that the payload size is only 8 kbps. Rest of the bandwidth is consumed by RTP and other headers. SBO works here. It has own proprietary VoIP protocol which can replace the RTP and only transmit payload size thus reducing bandwidth consumption.

    Key Features of SBO:

    • The most important feature of SBO is, it can reduce bandwidth cost directly by 80% without degrading service quality.
    • SBO works behind any type of firewall and NAT. That means, it has anti-block feature.
    • Works with all commonly used codecs such as G.729, G.723 etc.
    • Multipath: SBO Multipath allows you to use multiple number of internet connections same time. These connections can be used simultaneously for your VoIP termination establishment which can balance load among available networks and it develop service quality expectedly.
    • Works with any type of internet connection i.e. GPRS, EDGE, 3G, 4G, Wi-Fi, Wi-Max, so it is possible to setup anywhere where mobile internet is available.
    • Highly secure and linux based software.
    • Full featured billing platform

    Hard Phones

    Standalone Ethernet Hard Phones (voice only)
    An Ethernet hard phone is a self contained IP telephone that looks just like a conventional phone but instead of a conventional phone jack, it has an Ethernet port through which it communicates directly with a VoIP server, VoIP gateway or another VoIP phone. Since a broadband hard phone communicates directly with a VoIP server, VoIP gateway or another VoIP phone it does not require any personal computer nor any software running on a personal computer to make or receive VoIP phone calls. It can be used independently, all that is required is an internet connection. While PC based software solutions are cheaper, a hard phone is the best solution for IP telephony.

  • 11/03/15--17:34: Asterisk sip canreinvite
  • Asterisk sip.conf, peer definition: canreinvite option


    Migration from Asterisk 1.2 to 1.4: The "canreinvite" option has changed. canreinvite=yes used to disable re-invites if you had NAT=yes. In 1.4, you need to set canreinvite=nonat to disable re-invites when NAT=yes. This is propably what you want. The settings are now: "yes", "no", "nonat", "update". Please consult sip.conf.sample for detailed information.

    canreinvite= was renamed to directmedia= in Asterisk 1.6.2 to more accurately describe what this setting does. See also the closely related setting directrtpsetup.

    Asterisk 1.8 added directmediapermit and directmediadeny to limit which peers can send direct media to each other.


    This peer option in sip.conf is used to tell the Asterisk server to not issue a reinvite to the client unless really necessary. This is used to interoperate with some (buggy) hardware that crashes if we reinvite, such as the common Cisco ATA 186.

    When SIP initiates the call, the INVITE message contains the information on where to send the media streams. Asterisk uses itself as the end-points of media streams when setting up the call. Once the call has been accepted, Asterisk sends another (re)INVITE message to the clients with the information necessary to have the two clients send the media streams directly to each other.

    • If one of the clients is configured with canreinvite=NO, Asterisk will not issue a re-invite at all.
    • If the clients use different codecs, Asterisk will not issue a re-invite.
    • If the Dial() command contains ''t'', ''T", "h", "H", "w", "W" or "L" (with multiple arguments) Asterisk will not issue a re-invite.

    'canreinvite=no' stops the sending of the (re)INVITEs once the call is established. From messages in the archives and the Asterisk handbook one finds out that the Cisco ATA-186 does not handle the (re)INVITE well. This is necessary if the client and the Asterisk server is on opposite sides of a NAT gateway or firewall.

    • canreinvite = yes "allow RTP media direct"
    • canreinvite = no "deny re-invites"
    • canreinvite = nonat "allow reinvite when local, deny reinvite when NAT"
    • canreinvite = update "use UPDATE instead of INVITE"
    • canreinvite = update,nonat "use UPDATE when local, deny when NAT"

    Note: In spite of its name 'canreinvite' being set to 'no' does *NOT* disable all reINVITE operations. It *only* controls Asterisk generating reINVITEs for the specific purpose of setting up a direct media path. If a reINVITE is needed to switch a media stream to inactive (when placed on hold) or to T.38, it will still be done, regardless of this setting!


    • reinvite=yes/no is plain wrong, even if you see it mentioned in example .conf files. The correct syntax is canreinvite=yes/no
    • Connecting media paths direct to an endpoint behind NAT won't be pretty. Especially if both devices are behind NAT. You might want to try using SER's nathelper in conjunction since can rewrite the SDP so that the private IP addresses are not included in the re-invite.
    • When dtmfmode=rfc2833, asterisk will send the RTP stream through asterisk. With dtmfmode=info canreinvite works properly.
    • Asterisk 1.8 added the media_address= configuration option which can be used to explicitly specify the IP address to use in the SDP for media (audio, video, and text) streams.

    Background info

    In general Asterisk supports 3 methods of media handling:

    ConfBridge 在新版的 Asterisk 10.x 做了許多更動。新版的文件可見於此 here. (Someone should add it to Voip-Info)

    Asterisk cmd ConfBridge

    ConfBridge此應用程式於 Asterisk 1.6.2.* 開始就有了, ConfBridge 功能上與 MeetMe 相似,但不同於 MeetMe的地方在於 ConfBridge 不需使用 DAHDI 硬體混音。 取而代之的是,混音直接在 Asterisk 內部直接做了。

    To get an up2date description of ConfBridge for your used Asterisk version execute "core show application ConfBridge" on the Asterisk CLI.

    • 'A' — 設為標記成員

    • 'M' — 啟用音樂等候,當會議室只有一人時,可特別指定音樂等候的等級,若未指定則使用目前頻道的設定或預設值
    • '1' — 不撥放提示訊息,當第1位使用者進入時
    • 's' — 當收到 # 號鍵時,出現語音選單 (普通成員是普通選單、管理員是管理選單)
    • 'w' — 等待標記成員進入後會議才開始(若有啟用 M 參數,則在那之前都會一直撥放等候音樂)

  • 11/03/15--18:14: IVRLuke
  • Recording prompts

    For your IVR configuration you will need first to record some sound messages.
    You can record your own sound files using the Asterisk. For this purpose you should add an extension for the recording in the extensions.conf file. In our example, you can dial the extension 100, after the beep you can start recording your message.
    To end the recording press "#". The message is recorded in .gsm format and is called recording.gsm in the /var/lib/asterisk/sounds directory. Asterisk plays back the message after you pressed "#"(after 2 seconds).

    exten => 100,1,Wait(2)
    exten => 100,n,Record(/var/lib/asterisk/sounds/recording:gsm)
    exten => 100,n,NoOp(${RECORDED_FILE})
    exten => 100,n,Wait(2)
    exten => 100,n,Playback(/var/lib/asterisk/sounds/recording)
    exten => 100,n,NoOp(${PLAYBACKSTATUS})
    exten => 100,n,Wait(1)
    exten => 100,n,Hangup()

    Here we are using Wait(), Record(), Playback() and Hangup() applications. You can see their descriptions by typing "core show application <application>" in Asterisk 1.4, or use "show application <application> (this will be removed in future).

    Let's make more clearness:
    Wait(2) - waits 2 seconds, then the dialplan continues to the next priority. The 2 seconds are to be sure that the channel is up and ready for recording.

    Record(file:gsm) - records from the channel into a file with format gsm. This application sets a channel variable named RECORDED_FILE, which contains the name of recorded filename.
    You can use NoOp() application to see what contains the RECORDED_FILE variable.

    exten => s,n,NoOp(${RECORDED_FILE})

    Playback() application - plays the recording file. This application sets the following channel variable - PLAYBACKSTATUS. The result is SUCCESS or FAILED.

    Hangup() application - hang up the calling channel.

    Implementing a IVR using menu structure

    The following is an example for an IVR system. You dial any number in the range [1-9] and you enter the IVR system. First there is checking if it is business hours and if you are, you will be send in the ivr-lang context, after that you will get the greeting message and during the message you can press a key from one to three to choose your language. According the number you pressed, you will be directed to the right extension (context).

    exten => _0[1-9].,1,GotoIfTime(9:00-18:00|mon-fri|*|*?ivr-lang,s,1)
    exten => _0[1-9].,n,GotoIfTime(10:00-17:00|sat|*|*?ivr-lang,s,1)
    exten => _0[1-9].,n,Playback(closed)
    exten => _0[1-9].,n,Playback(closed)

  • 11/03/15--19:34: Voice Broadcasting
  • Voice Broadcasting

    The following is the definition for Voice Broadcasting:

    • "Voice broadcasting is a mass communication technique, begun in the 1990s, that broadcasts telephone messages to hundreds or thousands of call recipients at once. This technology has both commercial and community applications. Voice broadcast users can contact targets (whether they be members, subscribers, constituents, employees, or customers) almost immediately." - Wikipedia

    Voice broadcasting phone software manages a database of phone lists as well as digitized phone messages. Using analog, digital or VOIP telephony components, these computers can simultaneously broadcast thousands of phone messages. Personalized information can be included in the phone messages through the integration of text to voice software.

    Advanced systems include telephony boards or software that can detect the difference between an answering machine and a 'live' person answering the call. These systems employ the logic to properly play a unique message to answering machines without message truncation.

    There are few enterprise-level commercial solutions for Voice Broadcasting. They include such functions as:
    • Possibility to play personalized messages to every recipient which consist from library of predefined messages (pre recorder by every client) and some variable information (dates, numbers, digits, amounts with currency and so on).

    VoiceXML and Voice Broadcasting

    Phone messaging systems and services automatically send phone messages from a computer system to a remote phone systems using XML push logic. For example, alerts can be broadcast to tenants in a building if there is a fire or disaster. Heat sensors with IP connectivity that are installed in the tenant building can initiate an emergency voice broadcast by sending a VoiceXML message . Other applications may be as simple as wakeup calls or weather alerts that are triggered automatically from a computer system or websites.

The gateway is like a web server, but it interprets VoiceXML command instead of HTML. You can test out VoiceXML applications with a hosted VoiceXML service, you could also setup your own VoiceXML gateway.
