Phone echo

Running CCM 3.1(2c). Phone load is P00303010102. Using DT24+. Before upgrading, I was running CCM 3.0(11) with absolutly NO problems. I checked the caveats/release notes and nothing is jumping out at me. HELP! Now I get echo, crackling, and just all-around poor voice quality.

Internal/LAN calls are fine. Just inbound/outbound.

Re: Phone echo

Silence suppression is set to false as well. (forgot to include that in the original post) Thanks

Re: Phone echo

For a quick fix revert the IP phone loads to something pre 3.1. (P003D310) You can still run CCM 3.1 with this. We have the same problem here and are waiting for a new phone load.

Re: Phone echo

The echos are on the ip side only after upgrading to 3.1. We've run this through TAC and are using the old loads to satisfy our users at this time.
