Problem with FXO Card

Hi!

I am having a problem with a VIC-2FXO Cards in a VG200 running Cisco IOS 12.2(23). They are connect to a PBX using Nortel ATAs. When a Call arrives to FXO Card, is forwarded to a IP Phone, and when the operator answer, the call hangs off in the PBX side, and the user on IPphone still see the call active, but the PBX user see finished.

here the sho run

voice-port 1/0/0

timeouts call-disconnect 5

timeouts wait-release 5

timing hookflash-out 500

connection plar opx 200

Re: Problem with FXO Card

does the call still seem as active beyond the call-disconnect of 5 seconds?

you may be having the dreaded 'FXO Disconnect' problem which in this case would mean calls out the FXO (to the PSTN) should not experience this symptom. calls into the FXO (from PSTN) will experience this symptom.

if your FXOs are loop-start then they will depend on the calling switch (PSTN switch) to tell the FXO a call is terminated. this leaves the FXO in an off-hook state, even if the other side of the call has terminated.

there are a few techniques to get around this issue if this is what you're experiencing. see this link for more info:

Re: Problem with FXO Card

Yes, it show the next status:

VG200#sho mgcp con

1. aaln/S1/SU1/1 C=,57,-1 I=0x0 P=0,0 M=0 S=1,0 CO=0 EC=1 R=0,0

Total number of active calls 1

But all has been on-hook in the phones.

I reviewed that document before and try some technicals from there.. but no one works.

Any help will apreciate.

Thanks
