Title: Modified SDP Header
Post by: GManNAtl on Thursday 30 May 2013, 07:10:36 am
I am having problems with some features of my IP-PBX behind a Community 2.5.1.  The Endian is modifying my headers during some of my VoIP calls for some unknown reason.  I have posted two captures below, one is from IP-PBX and the other I did from within the Endian with tcpdump on the external interface.  As you can see the Call ID is the same, but for some reason when the packet went out of the Endian it changed the (c) Connection Information to some bogus IP address of 134.2.0.0.

What the heck could possibly be going on?

Any help is GREATLY appreciated.
