No audio Inter -Cluster Trunk (Non - Gatekeeper Controlled

[jcanales]

Hello:

I configured an Inter -Cluster Trunk (Non - Gatekeeper Controlled )
 and establishes communication call but can not hear anything .
any idea to solve
Thank you

[Jaime Valencia]

Is there full routing between the endpoints?

Nothing blocking it?

[jcanales]

The connection in the firewall is full.

the gateway has only setting allow-connections sip to sip.

you need allow-connections h323 to sip ... and so on ?

that command has an impact... ?

Thank you.

If this calls are going thru an ICT, there's no GW involvement, not sure why you bring that up...

Jaime can you help me on the same issue?

8845 IP Phone->CUCM2 of 3 in US -> ICT over DMVPN ->China->CUCM2->IP Phone

No audio but call connects fine.

Note* Media Termination point required is not checked on the ICT.

Run on all active nodes is not checked on the RL or the SIP Trunk.

Ping Times are 210ms.

I do not have access to CUCM in China. Only US.

CDR from China shows two IP Addresses for destination. 1. Destination IP Address (CUCM 2 US). 2. Media Destination IP Address of US IP Phone.

Helppp

Jamie deeper info...

US IP Phone->Specific Route Pattern->RL(Run on all CM Nodes not checked)-> CUCM1->ICT CUCM2(Media Termination Point not checked nor is Run on all Active CM Nodes)->DMVPN 210ms between CUCM's->ICT CHINA CUCM2(not sure what is checked. No access)->China IP Phone

No audio but normal call clearing.
