[SIPForum-discussion] 2 headers in one Packet?

[John Lloyd]

Hello All,
 
I've found that in certain call flow scenerio's Avaya Communication Manager is sending 2 headers in the same Packet, a 100 and also a 183.  I've looked through the SIP RFC but can't find any information on this.
 
This isn't breaking the call flow, but I'm curious if the UAS is violating RFC 3261.
 
Thanks,
John
