We have a CCM 4.2. WE are experiencing intermittant oneway audio on offnet calls. Weare going out a Cisco 2851 and 3845 gateway. All the reported incidents report that IP side can not be heard out to PSTN called party.Both gateways are using PVDM2-64 SIMMs. Any ideas what is causing this intermittant problem
As you have two voice gateways, the first aspect to investigate is which of these gateways is possibly causing the one-way audio?
Are both gateways being used for all outbound calls? Or is each gateway using separate carriers for different billing purposes?
Determining which gateway the outbound call is established through will help to isolate the problem.
As the problem is intermittant I suspect that it is only calls which are established over the gateway which is possibly the second gateway within the route-list when all channel on first gateway are busy?
As the previous post suggested, ensure that the IP address used for signalling on either gateway whether it is H323 or MGCP is reachable from all respective voice VLANs.
