SDPC-120 — Data port assignment failure
The SIP proxy tries to choose a free port when establishing a new data (media) channels. It starts trying by the port number originally offered by the peer, and continues by succesive even numbers. Number of attempts is equal to the sockets table size (the SOCKETS-TABLE-SIZE configuration item).
If this search fails, session is terminated.
Check the state of the system. This event should not occur in normal circumstances.
