[OSL | CCIE_Voice] Voicemail not working for some calling users
Hello experts, I have the following scenario: Phone A at Company A HQ(CUCM 8.0 + Unity Express 8.0) -- LAN -- ASA - 2Mbps WIRELESS LINK -- Checkpoint -- LAN -- Phone B at CompanyB HQ _ Phone A @ Company A can call Phone B at Company B. Phone B @ Company B can call Phone A at Company B. PSTN users can call Phone A @ Company A. PSTN users can leave a voicemail to user phone A in company A. Phone B @ Company B CAN'T leave a voicemail to user phone A in company A. __ At first, we were thinking about a transcoding issue but everything seems to be OK. As we are limiting bandwidth to 128kbps between Company A and Company B, we're using G729 codec for calls between these sites. We have a XCODE at the gateway and it is registered correctly and seems to be working OK. In the past, we have had issues regarding blocked ports on the checkpoint causing 1-way audio, or Phone B not hearing PhoneA's music on hold. Do you think it could be part of the issue again? We're running out of ideas as we have checked everything we think could be causing the issue. Thanks a lot!

I would do a wire shark packet capture on the phone side and see if you can see both streams. If you can't repeat that at every hop until you find the break in the stream.

Hi Daniel, Can you give us the following information please? 0) Describe the problem better, when the call is forwarded to voicemail what happens? a) Call does not establish? and after some timeout it disconnects? b) call establishes but there is no audio? phone in company B does not hear anything from UC? c) call establishes, and company B can hear UC announcements, but can not leave voicemail? 1) What region are the HQ Phones in. 2) What region is the UC in. 3) What region is the transcoder in. 4) What region is the company B telephony system in. 5) What protocol is the company B using? SIP/h323 ? 6) What are the inter-region codecs between these? 7) on the transcoder: a) show sccp connections (when the call goes to voicemail.) b) show call active voice compact c) show call active voice brief 8) if company B is h323 trunk/gateway - enable inbound fast-start, and select appropriate codec for this. You might need MTP depending on the following: a) In the company B phone system, enable outbound fast start. You will need MTP in the company B side for this. b) If you can't enable outbound fast start on company B side, then check - MTP required box on your call manager, and configure MTP resource. 9) if it's SIP integration, do same as in 8b - check MTP requiered, and configure MTP resource.
