    Hi,

    I'm using Elastix 1.6-12, and have a SIP trunk to my local Telco. I have one username (basically a tel number) to authenticate trunk. I have 100 other numbers (DIDs) assigned to that trunk as well. Problem is setting the correct CLID for extensions (one extension per one DID) from elastix gui.

    Outbound CID that I set to each extension gets out in SIP message as follows:

    Code:
    From: "Outbound CID" <sip:FROMUSER@ims.telco.com>;tag=as3218f533
    where FROMUSER is number that I use in fromuser=xxx filed in trunk settings.

    Trunk settings are:

    Code:
    disallow=all
    allow=ulaw&alaw
    canreinvite=no
    context=custom-get-did
    dtmfmode=rfc2833
    fromdomain=ims.telco.com
    fromuser=123456
    host=ims.telco.com
    insecure=invite,port
    secret=xxx
    type=peer
    username=123456
    
    My Telco ignores the >From: "Outbound CID"< part of the filed, and passes out the FROMUSER - <sip:FROMUSER@ims.telco.com> as CLID to the network.

    So, basically, I can set out 1 number in the trunk settings that will be CLID for all extensions, and I need the ability to set CLID for each extension...

    Any help?
    Thanks
