I could use some input here.

The customer has a SV8100 with IP phones & a PRI from LOGIX Communications in a stand alone environment, no Netlink, CCISoIP, or remote phones.

The customer experiences one way speech path intermittantly on inbound & outbound calls whereas the outside caller cannot hear the customer but if the customer puts the call on hold & then picks the call back up, usually the speech path is back to two way.

We have swapped out the IPLA, PRT & the CPU. Upgraded the CPU to 3.12A per the NTAC. They have my wireshark, DIM traces & a copy of the database but are having difficulty nailing the cause down.

Any ideas are greatly appreciated here.

Thank you.
