Each IP extension in the office had been configured with an Outbound CID, so calling outside numbers will display a unique CID to called party - and this is working.
But, when I try calling our branch office connected via VPN - it now displays the configured Outbound CID and not my local extension. How can I correct this?
i.e: Me (ext. 2001) calling branch office (ext. 3001) will show my Outbound CID (XXYYYYYYY) and not 2001 anymore.
My SIP trunk to branch office had been configured with CID Options set to: Allow Any CID.
