If you are using UDP for sending SIP packets the phones cannot receive the packets because of UDP fragmentation. You have to switch to TCP transport layer (or TLS, if you have a certificate that the phones accept). Quote Link to comment Share on other sites More sharing options...
hosted Posted November 12, 2008 Report Share Posted November 12, 2008 huh? you can do dialog states with UDP? I have a few phones that work just fine, I dont like doing them on polycom phones however. Quote Link to comment Share on other sites More sharing options...

I have a few phones that work just fine, I dont like doing them on polycom phones however. The problem is the initial message after subscribing for BLF. This message contains a list of the buttons, and depending on the length of the names this packet can easily get longer than 1492 bytes. If you just have 6 buttons, then that message size is usually enough. Quote Link to comment Share on other sites More sharing options...

There is something at http://wiki.pbxnsip.com/index.php/Polycom#...transport_layer, maybe just give that a try. Quote Link to comment Share on other sites More sharing options...
