We currently have about 60 cisco 7940's, which were converted from cisco call manager to be used for asterisk. We're running 1.2.1 stable on 4 systems (primary server, backup server, gateway, and voicemail). The phone lines come into the gateway on a digium te405p. The problem we're having is that the 7940's are echoing on outgoing calls, and I'm not sure what else to try (I did just recompile zaptel with a different echo canceler to see if it would help), but I seem to remember asterisk doesn't do echo cancellation on outgoing calls. I researched a bit on qos and latency, but there's maybe a 10ms latency between the phone and the outgoing line, so I ruled that out pretty quick. Any help is greatly appreciated.
