We have a working Trixbox (Asterisk 1.4).
We are using Zoiper biz as the softphone.
Zoiper has a feature to pop-up web browser on call ring with DNID in the url.
For this to happen, zoiper has asked us to tweak the SIP header slightly so that the DNID value is included in the "To" of the SIP header.
So I am looking for someone who can do this bit for me.
Need to put DNID in the "To" SIP header field so that Zoiper can capture it and include DNID in the pop-up url.
