I have an MGCP gateway with 4 FXO. Only 2 FXO er connected to Telco lines.
One FXO/Line hehaves very normally. However, When I call the num asssociated to the second FXO the attendant internal IP phone keeps to ring one time then stops , then rings one time again , then ring one time ,.... continuously.
I can't see any prob in the config and the debug commands output
The caller hears a continuous (normal) ring.
Any suggestions to resolve this.
