[SIPForum-discussion] contact / Via header NULL

[fråmedrëlay]

Hi All,

I get a call from CA, however I do not see contact header and Via header, it has NULL Values. Could someone confirm two things.
1. Why the value is set to NULL (as per the CA guys, its for security issue).
2. its working as of now, however I see BYE getting timeout. I get a parameter above the Invite which says SOURCE = "CALL AGENT IP ADDRESS"; So when we sent 100 trying and 200/180/183 etc, we send it to call agent IP. I see a problem with BYE getting timeout. Can someone confirm If this is Ok?
