Hi - I wanted some advice from people on whether a digium card for timing will provide better conference call quality compared to ztdummy on Asterisk 1.2.4.
My conference calls number comes in via IAX2 from the PSTN.
I do get some time delay in calls and echo when people are talking from speaker phones. It’s quite noticable, and leads to very stilted conversations where people talk over each other.
Is this just a feature of VOIP or Asterisk or will a Digium card cure the problem?
The hosted box is 3.0 Xeon with plenty of memory.
Any advice much appreciated.
