You mean that SIPHANGUPCAUSE makes sense after executing
Dial(SIP/exten at IP,,) and not Dial(SIP/exten at IP&SIP/exten at IP,,)? Ok, then
we could return the one that answered. I guess that you can reply more
cases that doesn't make sense, we could limit this variable to the
easiest one (simple SIP dialing)

If the call goes to a non-SIP channel: I think that the name
SIPHANGUPCAUSE indicates that would not make sense to look on it :-)

I thought that SIP in Asterisk is enough important to include some
special variable (specially since we needed in a real case, together
with some other particular Header). I understand that, for maintenance
and leave Asterisk not-protocol-focused you decided to not include.

Anyway, thanks for your attention.
