Strange SIP Debug message 'SIP/2.0 200 Rawr!!'

[woody1848]

I was going through some of our SIP debug messages and I came across this:

(I have taken out our IP address for privacy reasons)

Received:
 SIP/2.0 200 Rawr!!
 Via: SIP/2.0/UDP X.X.X.X:5060;branch=z9hG4bK2F69AB6D2

Can anyone shine some light on this issue for me? I have searched for this and have not been able to find anything that explains what 'Rawr!!' means when found in a SIP message.

P.S. We are an all Cisco shop with CUBE, CUCM, CCX, and Unity running version 9

Hi,

I haven't seen this before. Can you try with another IOS (e.g. 15.4(3)M3) and see if you are getting the same message. Also, did you try to reboot the router

[woody1848]

Unfortunately, since this is a live production router I cannot change the IOS versions at this time.

This 200 message coming for Options and its received not generated by IOS . What is far end devices its Cisco or non-cisco

SIP response code status line field is customizable and different vendors use it differently as per their requirement. I don't think you need to worry here.

What's important is response code (2xx, 3xx, 4xx etc) to take decision on transaction. Status line has no role here.

For example when INVITE is sent and there is no user associated with the called party number, you will frequently see following response code;

SIP/2.0 404 Not Found

Although you have a choice to include better description in status line;

SIP/2.0 404 Please check the dialed number

Yeah you are probably right, since it is customizable the vendor could be manipulating that field.  I'm going to look more closely at these SIP messages and see if I can find out why they might add that into the 200 response code.

Thanks for your help Vivek Batra

You're most welcome.
