[Asterisk-Users] FW: Echo on incoming calls (PRI->SIP) but not on outgoing (SIP->PRI) (no html crap, sorry)

[fredrik.hedberg at telavox.se]

Hello all!

We have an E400P on a dual Xeon box with four EuroISDN PRI to the PSTN
and Cisco ATA-186 as SIP UA. 

We experience very large amount of echo (on -some- calls) when we're
doing PRI->SIP calls but not when doing SIP->PRI calls.

We don't think the problem is IP latency related (When calls are made
PRI->*->PRI we still experience the echo). What do you think?
