[SR-Users] SIPT append_body_part \x00 how to?..

[Sergey Basov]

Hi Daniel.

Thank you.

It works like expected!

Now when i do

set_body_multipart(,"2123894789_1257887457");
msg_apply_changes();
append_body_part_hex("01 10 48 00 0a 00 02 09 07 03 90 90 13 71 32 20 0a 04
02 13 73 12
00","application/isup;version=itu-t92+","signal;handling=optional");
msg_apply_changes();
sipt_destination($(rU{s.strip,1}), 31, 3, 0);
sipt_set_calling($fU, 3, 0, 3);

I got correct ISUP part.

Now I will try to document and commit some SIPT module functions to get
forwarding info.

Thank you Daniel.
