I had a 3-PRI trunk terminated into two seperate Cisco 2851VGs working fine - in an effort to consolidate gateways we added an additional VWIC to GW#1 and terminated the 3rd PRI into it - circuits looked clean, no errors but we began having one way audio issues as well as hearing other employees conversations from their desk phones, hearing faxes coming through the IP phones - real strange stuff, only on PSTN calls. After trying to troubleshoot for a while we resorted to moving the circuit back into the GW#2 and the problems ceased. The LEC says there is no need to change anything if we are moving he physical PRI to another box. I've got 2 PVDM2-64s in GW#1 and just 1 PVDM2-64 in GW#2 so don't think I have a DSP issue - Has anybody come across a similar situation?
Thanks in advance!
