hello,
sorry for the other message.
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
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
