Hello, Something I've been wondering about meddling with sip uris with Kamailio: I know it's possible to translate between a number prefix and a domain using PDT, but is this possible: Having a numeric or alphanumeric value stored in db, associated to a domain and appended to / removed from a number during processing a sip message? For example 112222333(a)mydomain.com --> 333.5555(a)mydomain.com where value 5555 and mydomain.com are associated to one another in db somewhere. In this example I could have a pdt with prefix 112222 and domain mydomain.com, but the value 5555 should be stored somewhere as well. So one part is to find a db table suitable for storing a value and associating it with a domain, and the other part is to change the sip uris. I'll appreciate any comments! cheers, Olli
