I have a dialplan rule with several gateways associated (a VoIP provider and a patton ISDN gateway). Now, if I call someone who desn't answer or is busy I see that sipx calls the callee twice. Even if the VoIP provider sends a 486 to sipx, sipx switches to the patton gateway for a second try. Is there any response code that keeps sipx from trying the next gateway(s) in the list? ________________________________________ A 6xx response code is supposed to prevent any proxy from trying any alternative destination. The problem with that is that further upstream there may be alternative destinations that should be tried. (See draft-worley-6xx-considered-harmful for more on those problems.) Unfortunately, SIP has no good solution for the "alternative routing" problem. (See the various versions of draft-worley-redundancy-response for discussion of that problem.)
