I want to
setup SER to forward calls to two or more asterisk SIP
servers, having the asterisk servers control authorization etc. Is
this
SER can forward calls to Asterisk. I did not understand the "asterisk
servers control
authorization" part. You mean authorizing INVITEs? Does Asterisk
support that? I think no. It will
accept your call and create another INVITE and send to the
destination. If you meant registration,
you can either register clients with SER or Asterisk. If you register
with Asterisk, then there is
no need for call forwarding using SER. (I know, your Asterisk
knowledge is better than mine :-)
Asterisk does indeed support INVITE auth. I want all REGISTERs to go to
the asterisk box(es) but I want to allow one of them to die. All data
about the register is stored in a common database between the asterisk
boxes, so it's no problem sharing that.
possible?
Also, is it possible to have SER detect if one of the
asterisk servers fail, and if failed, use the other one? This would
leave me with only the SER box vulnerable alone.
Yes. This is possible. You can have failure routing in your script and
check for the status of
replies and then decide on what to do. Maybe like forwarding calls to
another Asterisk or send to
a voicemail server etc.
probably something like that, or just 'try forward to server A, didn't
work, try server B, etc'
btw, is it possible to schedule this via random or round robin somehow?
