FXO port issue

Hi Mohammad,

Is it newly implemented??

Can you send me the configuration of your gateway and how many FXO ports you are using???

Have you checked it by doing shut and no shut to the specific FXO port??

Re: FXO port issue

Thanks Sinqh and sorry for being late,

yes i tried to do shut and no shut, but later the issue returns again,

am using 2 FXO cards, i notice today that the dedicated port and other fxo ports remains off-hook status when i do sh voice port summ despite the user hangs up phone,, when the user try to dial another call, he receive a busy tone.

how i can solve the issue of fxo ports keeping in off-hook status after user hangs up the phone??

thanks

Re: FXO port issue

Hi Mohammad,

let try:

CIPC (softphone on PC)------CME(FXO)-------PSTN Network

Start wireshark and capturing,then make call from CIPC to PSTN network, let far side (PSTN) hang up first, until CIPC hears 'tut tut'...


Use wireshark to capture the packet from CME to CIPC (filter UDP packet between CME and IPCP).

Then upload .pcap file here, I hope I can support

Re: FXO port issue

Hi Mohammed

After the near-end user (using IP Phone) hung up the call and before he initiates a new call, please "show voice call status"

Besides,let make a test call (ex: through port 0/3/0)  and "debug vpm signal " and "debug vpm port 0/3/0" . After finish the test call, please get back with "show" and "debug" log

FXO port issue

Update IOS. When an IP phone hangs up, the voice port must hang up as well.

FXO port issue

Hi Paolo,

Not the ip phone which hangs up, the fxo port is the one which hangs and shows the yellow color from back of the router on the fxo port....

it is solved temprory when i switch off the router, then unplug and plug the fxo port,,,

If you dont mind,please i want an answer from you with yes or No in another matter,,,,

do the cisco CME support a voice calling solution that can be used to make a voice call thru Mics and external speakers which is is similar to hospital systems where they call thru external speakers for any doctor to attend the operation room???????
