Topology: Phone(31295)----EricssonPBX-(PRI-E1/QSIG)--3725Router--(MGCP)-UC601----IP Phone(30801)
What may be the cause of resource unavailable, unspecified disconnect message ?
When I try to place a call towards PBX that is from 30801 to 31295. I receive this error after 3 rings.
I get the following debug output:
