| I am having problems with clipping and echo. Here is the scenario. A caller in city A dials the Opt 11 switch in city A the call is sent from Switch A to Switch B which has the MerMail system that answers with the Auto Attendant. The caller selects a user in Switch A therein the call is routed back to Switch A. The systems ea. have a T1 going to a Cisco Router that is connected to the other ends Cisco router with a T1. The routers have silence detect turned off and no compression on voice channels now. I think the tie lines are doubling and tripling up on these calls creating this problem. Any ideas. | ||||||||

| Senior Member  | Every one of those T1<->Cisco conversions is potentially adding echo and definitely adding voice quality issues (both delay and impairement) due to TDM<->IP conversions. If you were using PRI trunks with MCDN between the sites, then the two legs would be removed. Fletch may have to chime in here, but even converting to IP Trunk may allow the legs to be removed. |
