[Users] prefix routing for one account

hi all, I need to route prefix to te one subscriber. It's something between PDT and ALIAS. ALIAS The R-URI shoult not be replaced by one in the alias table PDT The voip domain is rewrited, but I need to leave the old one. WHY ??? I want to connect some SIP PBX (asterisk) to our VoIP network and give them more numbers / prefix. I dont want to put it into routing logic eq (if sip:0123XX@domain; then). The best case is to call some function as PREFIX, which will lookup into PREFIX, SUBCRIBER and LOCATION table and just call t_relay function. Is there any other solution ??? best regards Peter Hudec -- Never step in anything soft.
