Hi Adrian, Jan, this is a good initiative. As a litle contribution i sugest the introduction of a "strip" column in the lcr table and the logic in the module to strip digits in the dialed number before prepend the "prefix". This digit manipulation is commonly needed in inter carrier routing.
Yes
curious: (Adrian): You make the gateway lookup using a loop function that make several selects to db after obtain a match in "destination" ???
Yes because you might have 5 gateways with different priorities used in each failure route
Thanks Ezequiel Colombo

Yes there will be some additional support to make sure same route si followed regardless of how the phone (mis)behaves.
What does that mean ? Record-routing will do the job for you and if it is broken in the phone then there is a really high chance that it will have severe interoperability problems, so why bother with storing additional session state ?

Adrian/Jan,
I have following setup.
UA--(registered as friendly name - ranga )--ser--PSTN.
For termination, our provider's PSTN GW mandates Contact header to be the proxy address because we asked for origination on our proxy. This has become a problem as original contact of UA is lost at the server. Subsequent ACKs or BYEs will never reach UA if we change the contact.
Second scenario where friendly names are not validated at the pstn gateway. They require a DID to be mentioned in the From uri.
This kind of specifications keep changing from provider to provider. Is there a work around for this without much deviation from SIP?
In any of the above scenarios, origination was never a problem. We were able to seturi using a module that reads our user mapping information.
Thanks in advance. Ranga
