VOIP Configuration between FXO and FXS

Unanswered Question
Aug 20th, 2003
User Badges:

Dear Sir,


We have implemented Voice over IP on our IPLC circuit between foreign office and India office.

Topology is such that our foreign office is having 1700 series router with wan card

(Wic-1T) and one two port FXO card connected to PBX for PSTN and local connsctivity.

India end we have a cisco 1700 router with wan card (Wic-1T) and two port FXS card.

Also we have many other branches connected to India office router on point to point lease links running data and analog voice (FXS).

We have configured voip using PLAR feature between foreign office FXO and india office FXS card.

1) Currently India office users via IPLC can communicate over voice and data with the foreign office (FXS to FXO).

2) Foreign office users can communicate with the india office users connected to IPLC link (FXO to FXS)


3) India office users can communicate voip with other branches in india (FXS to FXS)


We want to configure the foreign office router in such a way that foreign users are able to talk to remaining branches in india office (FXO to Many FXS cards)


Will putting voice route in the foreign office solve the purpose or we need to change the router voice config from PLAR mode to some other mode.

How the foreign office PBX will differentiate between point to point voice calls and other location voice calls.


Will the PBX/Router in foreign office be able to give dial tone to the FXO card.

Can we use the india end router as a voice switch for routing voice calls between foreign office and all the branches in india.

Any suggestions/config will be appreciated



Thanks

If I understand correctly you have FXO port in your foreign office with connection plar so any call coming in goes directly to your india office. Assuming you can ping to all other office branches in india from the foreign office, all you have to do it to take out the plar command and set dialplans for different sites. When a call would come in on the FXO, the caller will hear one short ringback and then a dialtone which is coming from the FXO when it goes off hook. After that user can dial the number say 1234 to go to one site 5678 to go to another site etc.


I hope that helps.

The configs that you have pasted are for calls between the two sites only and they should work fine.

In the US the you are sending only 3 digits to the PSTN. Is this what you want to do? If you have to send variable digits you can use 9T instead of 9...
