[Users] avp_check in OpenSER 1.1

Hi Everybody, I have a question regarding avp_check() and reverse-DNS-Lookups: I wanted to do the following in the routing logic (simplified): loose_route(); if (avp_check("$dd","re/192\.168.123.(1|2)/g")) { The idea was to allow flexible re-routing to another proxy in case of loose-routing. One proxy would be the alias of the other, and so far, everything was fine. What happened now: We had a customer, who's IP could not be "reverse-lookuped" properly, the DNS-Server ran into an timeout. After we removed the code-snipplet from the routing, everything was fine (again); except this functionality drawback. I believe, in OpenSER 1.2 i could replace it with the following, to avoid the reverse-lookups: if (($dd == 192.168.123.1) || ($dd == 192.168.123.2)) { Am i right? Would this work? Can i somehow avoid the reverse-lookup in OpenSER 1.1? Thank you everybody, Carsten
