Cisco ATA-18x Series Analog Telephone Adaptor
Cisco's product pages:
The ATA 188 adds a switch with a second ethernet port.
These devices convert two analog phones to IP phones and support the following protocols:
(Note: You will most likely need to download a firmware package to convert the device for the desired protocol.)
(Note: Firmware packages require a contract to download.)
If you purchased the ATA new (not though a VOIP provider,) you get at least one free support call. If lucky and you press them enough, they will give you access to the SIP firmware for download. If you go the contract route, the SmartNet package that applies is part #CON-SNT-ATA186 for the 186 and CON-SNT-ATA188 for the 188.
They support the following Codecs:
- G.729, G.729A, G.729AB2
- G.723.1
- G.711a-law
- G.711u-law
