FXS port stays off-hook

[jseynaeve]

Hello all,

I have a problem with FXS ports on a CISCO2900.

When i call over SIP-trunk or BRI-port, voice is working ok, but when hanging up the FXS port stays in the off-hook state.

voice-port 0/3/0
output attenuation -6
cptone BE
timeouts ringing infinity
!

dial-peer voice 100 pots
destination-pattern 300
port 0/3/0
!

The router has BRI-ports to the outside and a SIP-trunk to the CUCM, but as either show the same behaviour i guess it must be something in the router itself, all ideas are welcome.

Regards,

Jan.

Which IOS are you running ?

[jseynaeve]

that would be:

C2900 Software (C2900-UNIVERSALK9-M), Version 15.1(2)T1

Does a shut, no shut of the port brings it back to normal? Is the port SCCP controlled or H.323?

no, after a shut it seems to keep off-hook too, but eventually it does go back on-hook ...

it is with a SIP trunk towards CUCM

Try maybe 15.0(1)M5.

If still trouble you must start collecting traces.
