I'm encountering problems with a FXO / FXS configuration.
I have the following config:
CIPC --> CCME-1 --> FXO --> connected to FXS port -> CCME-2 --> CIPC
Outgoing calls from CCME-1 to CCME-2 phones are working.
Incoming calls from CCME-2 to CCME-1 phones are not working.
The call is established for 1 to 2 seconds and then disconnects.
I have configured an outgoing dialpeer on the CCME-2 router, pointing to the FXS port. Have an incoming dial-peer on CCME-1. I have also a connection plar opx on the voice port in CCME-1 pointing to the CIPC.
The voice port configuration on both sides is the default config, I did not add any commands.
I don't have any experience with analog ports.
Has someone an idea where the problem could be?
Are you going through a pbx? cme-1 is getting reverse battery after connect, configure "no battery-reveral" under voice-port", or try swapping cable pins.
