Hi

I have the following setup

Cell Phone "Any Possible Number" ----Calls a DID number-----> DID Provider --> Forwards Call to my Openser --> OpenSer Server--> Forwards Call to Asterisk with A2B --> Forwards it to the cell phone of the user

In short, a person can call a DID and it gets forwarded to Openser, if the user is online using his sip phone, the sip phone rings and all is OK. However, if the user is not online I do forward that call to Asterisk and I want to forward it to the cell phone of the user.

The problem is that the FROM field and the SOURCE URI

What do you mean with "Source URI"? isn't it the FROM?

keep changing,they are in the from phonenumberOfCaller@DID_Service_Provider.com and I do want to charge the user for the call.

Why do you need to change it?

To do that I need to have the FROM field and the source URI to be the USER ID so that I can charge him for the call.

I don't understand why you want that, could you put an example?

So, I might have to change the source URI and FROM field of the packet and send it to asterisk..it would send the packet back to Openser and I have to change those back to what they were and then send it to the DID provider.

Please help me set this straight, can it be done ? Maybe not ? Maybe Yes...

Use the module "uac" in Kamailio to change the From user.
