Hi Harini
So, do you mean to say that, both the response (486, 600) may be sent to the client?
First 486 when the primary device is busy and then 600 if none of the alternate devices is free. right??

Hi Vijay,
Here is the ans for ur first question: diff between 486 and 600 response...
Suppose if user A is trying to call user B, then 486 response message is sent by user B in the following situation:
If user B's end system was contacted successfully, but the user B is currently not willing or busy or unable to take additional calls at this end system.
600 response message is sent by user B during the following situation:
The user B could be available elsewhere, such as through a voice mail service (if user B has registered for it). 600 (Busy Everywhere) response message is sent if the client knows that no other end system(such as voice mail service or call forward to another end system service) will be able to accept this call.
otherwise 486 response message is sent...
in both the cases, user A would hear busy tone on his/her end system...
for the call flows refer: http://www.tech-invite.com/Ti-sip-service-8.html
Thank you,
Regards,
Harini Dhanasekaran.
