FXO & VoIP

Hi,

Is it possible to place a call via a FXO port in both way ?

here is the network :

Operator<=>BRI<=>3640A<=>IP Network<=>3640B<=>FXO<=>switch Alcatel E10

Both router 3640 are in version 12.2(7a)..

The calls coming from the switch to the routeur via the FXO work fine.

But when I try a call from the BRI side it doesn't work, I can see the call arriving in the 3640B but no way to go out from the FXO.

Thks for ur help

sorry for my poor English ..

Re: FXO & VoIP

It should work, the POTS dial peer just needs to match on the number that comes in from the VOIP cloud. Don't forget a POTS dial peer strips off any explicitly matched numbers by default, so you may need to use the prefix command or foward digits commands -

dial-peer voice 1 pots

destination-pattern 5551234

port 1/0/0

prefix 5551234

or

dial-peer voice 1 pots

destination-pattern 5551234

port 1/0/0

forward-digits all

Re: FXO & VoIP

thks but I finally find the solution.

In the way FXO => BRI , the pb was that there was no calling number to match my dial-peer voip. So I've put the command "connection plar xxxxxx" on the FXO voice port to simulate a calling number.

In the other way (BRI => FXO) the pb was that there was no tone sent back by the FXO to the BRI. So I've put the command "voice call send-alert" on the 3640B to simulate a tone.

It seems to work now ....

thks

sorry i've made a mistake.

you should understand "called number" instead of "calling number" ....

Re: FXO & VoIP

Did you ever have any issues with this when the calling party hangs up before the called phone is answered.

I have this problem and can not find a way to terminate the call to the phone when the calling party hangs up before the phone is answered.
