I am using Polycom 331 and Polycom 550 at a remote site. When I call an extension, it rings for half a ring, then stops. I have captured Wireshark, and I think one problem might be that the INVITE message is being fragmented because they it is 1674 bytes in size, and are marked with the 'Do Not Fragment' mark. It may also have something to do with SIPx sending two invites to the phone. I see a reassembled INVITE message going to the phone.The phone replies 100 Trying, then i see another INVITE message come in (different sequences number, but same contents), then the phone replies 400 Bad Request. This is when the phone stop ringing and the caller gets sent to voicemail. What do you think the issue here is ? I have running lastest SIPx, 3.2.3 SIP load and 4.2.2 Bootrom. Thanks !
