[SR-Users] using set_body_multipart and append_body_part on on_reply routes

[Sergey Basov]

Hi David,

if you look at source code of the sipt module
https://github.com/kamailio/kamailio/blob/master/modules/sipt/sipt.c

functions sipt_destination & sipt_set_calling works only for ISUP_IAM.

But as I know from my tests ISUP encapsulation must be only in invite,
and is optional for other messages.
