FXO problem

[dimensyssrl]

Hi all.

We have a problem with a 1760 with CCME.

On this router we have two fxo connected to a PABX, configured as connection plar opx, so every call is diverted to an ip phone.

After 4 or 5 calls, fxo remain blocked (off hook), so it appears to be occupied.

If we shutdown voice-ports, and no shutdown after 5 seconds, all restart to work well.

Any idea?

Thanks

You may be having a supervisory disconnect issue if signalling is loopstart (default).

You may want to try using supervisory disconnect commands and/or battery-reversal, no battery-reversal commands to see if a combination of those helps.

If not, see if the fxo lines can be configured as groundstart on PABX side and put signal groundstart under voice-port config on gateway/router.
