[Users] detecting re-INVITEs and corresponding replies

[JF]

Hi all,

For detection of a re-INVITE request from the script is it sufficient
to detect the presence of a to tag using has_to_tag() function?
Eg:
if (method=="INVITE" && has_to_tag()) { ... };

What about detecting a reply to a re-INVITE in an onreply_route ? Is
it doable from the script? How?

Thanks in advance for your help.
