Hi all,
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?
thanks

Hi,
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.

Hi, if you do debug ccapi you will see why the call is being closed. Don't you have ip connectivity between the CMEs ? That would let you call over VoIP avoiding use of the voice port.
Hope this helps, please rate post if it does!

Likely CME-1 is closing the call.

I have a similar debug from the other side on CCME-1.
Would you suggest to configure anything on the FXO port?
If I establish a call from CCME-1 to CCME-2 the debug shows me, even with a regular call disconnect, a call disconnect cause value = 16

Can you talk few seconds and then it drops ?
Can you collect "debug vpm signal" on cme1.

no I cannot talk for few seconds.
E.g. if I activate AutoAttendant on CCME-1 and call the number I can hear from time to time the "welc..." then the call drops. Most of the tests I do ends without hearing anything. If I forward to Voicemail I did not hear anything, the call disconnects after 1-2 seconds (based on the CIPC infos). If I forward via connection plar opx to the CIPC I see the call ringing, and as soon as I answer the call, the call disconnects after 1-2 seconds based on the CIPC infos.
I attached the debug vpm signal infos.
thanks

Hi,
Thank you, using the no battery-reversal command the calls are now working!
And yes, the CCME-1 is working as PBX.

Glad to know it's working now. My question was if fxo/fxs are directly connected or what is in between.
Thanks for the nice rating and good luck!
