I thought I would start a new thread because this no longer has anything to do with ports and is an interesting problem. I have been having a problem with appia. We have one of their DID's installed, can make outgoing calls but incoming calls aren't working. I have a gateway set up for the trunk, using NONE as the template. We can make calls out and those work just fine. If we let the call ring, it goes to vm. If we pick up the call, the other end gets a dead line or a busy signal. The carrier in this case is verizon, through appia.
The following are their findings at this point. // Verdal found that it appears the customers PBX is not accepting the calls as g729 and they are sending back a 488 Not Acceptable attaching pcap \\ I'm not really sure what to investigate at my end. I believe sipx allows G.729 passthrough and the phone they are calling does have G.729 enabled. Not sure what else I can do at this end. Is this not something to do with the carrier and their not trying another codec so screwing the call? We also have flowroute and voip.ms sip trunks on the same system and both of those work fine in and out.
