Anyone any good with this? I have a site that has a qsig connection to a third party phone system and they want to show the 4 digit extension internally but outbound to have a full 10 digit caller id value. This involves only 4 numbers, and currently they get denied when trying an outbound call. I did try to add one of these numbers as a DID replacement under the sip peer but it looked to make no difference, hence this post
