CVP 3.1 in IPCC Enterprise and no voice coming

[awais.ahmad]

I have IPCC enterprise (ICM 7.0) with CVP 3.1 in comprehensive mode, i have a different IPT cluster to call IPCC agents. From IPT cluster employees can dial 8888 and Call goes to IPCC system on CVP main menu and can reach agents.

some times the call is established and voice can be heard but many times call is connected but no voice.

i made some test calls and attaching the traces for CVPA. For some calls voice came and some no voice.

if any one is having idea its really helpful.

Check the callmanager event log and ensure you have you are not running out of MTP resources. If you are using Software MTPs you may want to try cycling the IP Media Streaming Service.

Hi corey,

I saw on publisher i have the following error.

Error: MtpNoMoreResourcesAvailable - No more MTP resources available.

this error came last month and i restarted the service but it comes again.

Can i fix it by installing more DSP in voice Gateway. thanks

Do you have MTP checked on the CVP Trunks?

Hi chris,

Can you guide me a bit how can i check that?

I noticed that when a call is connected by PSTN there is no problem. only it happens from IPT cluster. thanks
