sorry the call-id was wrong. i really use the user part of the ruri, that
represent a phone number in my case.
your answer really helped me. I thik the first option will solve my problem,
the second might too but as you say i'll loose flexibility.
thank you

i want to know if there is a way of routing based
on patern matching
using
caller-id.
Basically, i want to route through a carrier if the call-id have some
pattern
Eg.:
international is 002-(country code)-(area code)-697699.
Long distance is (country code) -(area code) -123456
Local is 123456
The international and long distance change
If international then route through carrier1
else if long distance the route through carrier 2
else if local then route through carrier 3
Hi victorpy,
do we talk about the SIP call-id header field here? Each call should get a
unique one, so i don't think this is feasible. But hashing over the
call-id
is possible.
If you mean another header field, then you could just lookup the target of
the
call by some other means (e.g. from a DB table, set it from the script),
and
give the carrier id to the cr_route function with an AVP. The specific GWs
could then lookup by the cr prefix matching function for each carrier. You
can modify the string that is used for prefix matching as well, as is also
just a pseudo-variable.
Another option would be to just use the 'default' carrier in cr, and use
the
normal prefix matching via the R-URI to route the call to the specific
GWs.
But you'll loose some flexibility here, as you don't have the possibility
to
seperate your routing by several carriers anymore.
Cheers,
Henning
