That may be, however I have found stuff that it did not work with properly, and that is what I was commenting on. I do not know if there was a bug report filed specifically for the items I found, I told oej only because I knew he worked on sip, and that he would either have worked on or knew who did work on the rtp stack. He is the one that suggested that 10058 may address that since on the surface at least it did. As stated by Jason earlier, a packet trace would fairly quickly identify what was wrong with the original posters comments, as well as the stuff I found, since that is exactly how I found it. It may even be that the original poster was talking about other issues, there is less than enough info to say if anything I have talked about is the same as what other people talked about, for all I know there are multiple issues. What I do know is that a specific cisco device worked with a specific gateway (it wasnt mine the packet captures were provided by someone else, and the most that could be derived is they use a proxy that is known to not modify rtp, so useragent stuff was not available) yet asterisk did not work with that same gateway, and the differences all revolved around malformed rfc2833 packets. I dont even know which cisco device it was that worked (depending on revision and other things it may be different output ...) I do know it wouldnt be hard to make the list for anyone who is reasonably competent at looking at packet traces, all of the anomolies that I discovered had to do with basically "numbers" not being incremented properly (such as the timestamp) and this was either 1.4.15 or 1.4.17 at that time. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast +44 28 9099 6461 US +1 516 687 5200 The GPL is a software license not a religion _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
