Same problem here, the far end has to complain to Verizon for anything to happen unless you want to get an echo canceler. I have know calls routed via a ISTP provider that is known not to echo on Verizon networks.

This is a weird one. Network: Asterisk ver 1-0-9 on DL360. 10 Cisco 7960g phones with 3.8.2 SIP Load. Gateway - Cisco 2811 router with 4 x verizon bri's. Network - Private vlan with 1ms response times to all devices. Issue: Intermittent echo on outbound/inbound calls. Users hearing their own voice about 0.5sec later. Tried so far: Upgraded firmware on some phones to 3.8.2 Upgraded software on Cisco router. Changed gain and attentuation settings on cisco router Got Verizon to test bris Moved rtp from asterisk direct to phone and router (canreinvite=yes) load tested asterisk None of the above made any difference. They are hearing their own voice so that means the issue is on the far end. But should it be up to me to control the possible delay or slippage in the verizon bri network? Any help much appreciated.
