Dear support
 
Could you take a look and give me comments about this problem?
Here is the info:
 
------------------
Background
------------------
I bought a sangoma card and license. Now I can make SIP<->PSTN call.
For some special application, we need to fetch the raw isup message from sangoma/wanpipe layer to freetdm layer, and vice versa.
 
------------------
Problem:
------------------
While, at sangoma layer, it just provides the structure like SiConEvnt in sit.x. If I want to push raw-isup to freetdm, I need to re-encode from the structure. 
 
And more, if I want to pass one presented ISUP from freetdm to wanpipe, I have to re-decode firstly and then push the decoded info to the structure.
 
Is there anyway to get/push raw ISUP message between freetdm and sangoma/wanpipe? That also would be accept to do code change on sangoma/wanpipe code if possible.
