Re: VG224 and modems

Hi Ken,

Here is an excerpt from the SRND doc for CCM 4.1:

Modem Tone Detection and Signaling

"Modem relay supports V.34 modulation and the V.42 error correction and link layer protocol with maximum transfer rates of up to 33.6 kbps. It forces higher-rate modems to train down to the supported rates. Signaling support includes the session initiation protocol (SIP), MGCP/SGCP, and H.323:

V.90 Support

Currently, Cisco equipment supports only V.34 modems. Although V.90 modems will function on existing hardware, and speeds higher than V.34 (33.6)speeds can be achieved, full V.90 support cannot be guaranteed."
