Chris,
The t_check_status("486") does exactly what you want.
Zeus
an example for a creating a header when diverting to
voicemail for a negative response. To support the draft
http://www.ietf.org/internet-drafts/draft-levy-sip-diversion-0
8.txt a reason (e.g. 486 busy here) would need to be understood in order to
support
the diversion header. From the example and the ser
documentation, it
appears as if
there is no current method to detect exactly which 4xx
response was
returned. Is my
statement correct?
