Re: CME with FXO

Under the voice port, configure "connection plar opx XXX" where XXX is the pilot number of the queue service. Queue is configure with "bacd-aa", if you think you don;t need queues, you can configure the pilot for the ephone-hunt directly.

Hope this helps, please rate post if it does!

Re: CME with FXO

Hi, are you sure the port doesn't go "dorm" after few seconds ? Anyway, expecially when using b-acd/AA you will need to configure disconnect supervision:

The FXO port can be used exclusively with analog pots lines.

If you was to use ISDN BRI instead, you would never have the disconnect problem.

Re: CME with FXO

Yes, this function is configure I make test with all the options in the web page but continues working worng:

Voice card specific Info Follows:

Signal Type is loopStart

Battery-Reversal is enabled

Number Of Rings is set to 1

Re: CME with FXO

Hi, that is very strange, if you answer the call then hang up the IP phone, the voice port must also disconnect and be ready to take a new call in few seconds. Send output of "show voice-port x/y/x' after you're done talking and have hang up on the IP phone.

Re: CME with FXO

See attach please.

Re: CME with FXO

Ok, I assume that this happens with the IVR application you mentioned in the other thread, because it's impossible to happen for a normal call to phone, once hang up the IP side, voice-port must go dormant.

Re: CME with FXO

Do you know something about the IVR.

Look the attach the IVR resides on the flash memory. Is the autoattendant.

Re: CME with FXO

When using IVR, if you don't have disconnect supervision working, the port will remain up if the caller hangs up before connecting to a party.

It will remain so until IVR times out or call goes to an operator that will hear disconnect tone.

Re: CME with FXO

But in this case the disconnect supervision is working and there is a time out (param aa-htimeout 10) in the IVR.

Re: CME with FXO

I understand, so you would need to take some debugs (vpm signal) to see what is going on.

Note if you use b-acd/aa, you don;t need "opx" on the lines, because the call is always answered (exception when using silent drop-trough mode).

You can also try IOS 12.4(11)XJ4 that is know to have less bugs than others.

Re: CME with FXO

The problem is fixed the solution:

In the voice port use tiem outs like this:

timeouts call-disconnect 0

timeouts wait-release 1

timing hookflash-out 500

connection plar opx 3002

I am from Saudi Arabia. I use STC analog lines at my office. And this command under my voice port worked like a charm. Hope it helps
