Hello.
Kamailio 5.2.1, Debian 10.
I need to change session name (s=) in SDP before relaying it to next hop,
and for unknown reason I can't do it with virtually any TEXTOPS function,
everything replace*, subst*, *body*... For example this from TEXTOPS
documentation:
subst_body('/^s=(.*)/s=root/')
just before 'final' t_relay().
Either Kamailio just adds "s=root" to SDP leaving first "s=" intact,
or
adds just "root", or does nothing.
Also I've tried msg_apply_changes() before and after these manipulations,
still no result.
Is it possible to make this in Kamailio without source code modification?
