Hello.
I am having configuration issues with ser when dealing with users who
have voicemail and desire a timeout after a set number of rings, and
those who don't have voicemail and desire a very long ring count. Here
is the example:
Phone A has voicemail
Phone B does not have voicemail
Works:
Phone B calls A. A does not answer. After a set period of time
(fr_inv_timer=24), the user is proxy'ed to voicemail.
Doesn't work:
Phone A calls B. B does not answer. After a set period of time, the
proxy responds with a 408 and the transaction is CANCELed .
The example above is a case when I just want to proxy the INVITE to a
user without setting a timer, stateless. I would consider sending the
original INVITE using forward() for users without voicemail, but the
parameters require a port and IP, of which exists in ser.location and I
may fork to multiple contacts for the user.
In addition, when responding with a 408, how does the proxy
differentiate between a timed out INVITE (after a set of retries) and a
transactional timeout (that had a provisional response)?
Looking forward to the Paris show (and the food and the wine and... :->
)
Regards,
Chris
