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? Regards Fredrik Hedberg
