[Freeswitch-users] How to get the raw ISUP from sangoma/wanpipe

[xiaofengcanyuexp at 163.com]

I'm taking use of below call model:

 SIP<--->mod_sofia ---- mod_freetdm---[sangoma]--wanpipe<-->E1

Now, I want to get the raw ISUP at [sangoma] part.  The current situation is, the wanpipe provides some ISUP message structures in "sit.x", which is the extractor of raw ISUP.

Anyone know how to get the raw ISUP excepte to re-encode from the structure? Is there any API?

Thanks
Windy
