I have a dial out system that has a SIP trunk to Callmanager. Whenever we kick off a dial out Callmanager complains of no MTP resources. The SIP Trunk in callmanager has a media resource group list with MTP resources. They are software MTP's and not hardware.
The dialout system is using G711 so I would think that the software MTP would be OK.
On the SIP trunk I do not have the must ue MTP checked. The CCM version is 6.1.4. Any ideas appreciated. Thanks
