I really need your help !!

Hi people,

Iam installing a VoFR link, in theory, it is too easy but, I can not do it yet.

Thing is, from an internal PBX in the main office i took two analog lines, and they are connected to a FXO port in a 2620 router, in the other side(branch office through an IP Network) I has a 1751 router with two FXS ports, then, i need to receive the original analog lines and install two phones.

But it seems it is too dificult for me.

can somebody help me, it would be really valued.



Re: I really need your help !!

Under your voice ports you need:


connection plar opx XXX

The XXX will be the far side port destination pattern. You need this in both directions.

Please rate helpful posts.

Re: I really need your help !!

lack of opx option may be due to old software on the router.

you will quickly learn that running the latest code is very, very important.


Re: I really need your help !!


Did you try connection plar XXX? This should still ring the phone, and give you PBX dial tone when you go off hook. The opx option allows the router to extend the ring without answering the call first. This is helpful if there is ring no answer forwarding on the PBX lines.



Re: I really need your help !!

on the remote end try this

enter voice-port command (for your FXS port)

under voice port put station id number , which is the number of your extension.

on the remote side configure pots dial-peer

So remote side you might have something like this

dial-peer voice 1 pots

destination-pattern 2xxx (extension pattern)

port x/x your voice port

then you will have a dial-peer voice 2 VOIP

with destination-pattern XXXX - head office extension

session target of you head office rtr

dtmf - for signal

On the head office router need to configure the reverse to reach the remote. namely the destination-patterns will change and the IP address.

on the PBX you also need to tell it to pass those patterns through the fxo lines to the rtr.

Hope i understood correctly and helps at little.

You didnt specify where you were with the configurations as yet. can you dial to from the PBX phone? can you dial from the remote side?
