Hi all,
I hope someone can help, as I have an urgent problem.
I've got a production Asterisk server thats been deployed, but we are seeing
a strange voice echo problem. There is about a 250ms echo for the users in
the office, and they are hearing their own voice back at them.
I'm running the CVS Head code, on RH9.0. This is on a P4 box with 2gb of
memory. The client SIP phones are Polycom Soundpoint IP600's, WiFi ZyXel
2000w handsets, and X-Lite (free) PC clients. All see the same problem.
There is a bridge into the POTS (BT's SystemX) using a Voicetronix
OpenSwitch12 card and the vpbhp driver.
The echo occurs on both SIP->POTS calls, and SIP->SIP calls. I've tried a
number of volume adjustments to correct the echo but it is always the same.
If anyone has any ideas I'd really appriciate some help, as this is a major
urgency,
Many many thanks,
Ian Bonham
