Hello Prakash,
Basically we will see this behavior, when registrar challenge the endpoint for
authentication. So 401 response should contain an nuance or authentication
string along with realm if any. So behaviour from endpoint should be to include
those values in next REGISTER message. If authentication completes then you
will see an 200 Ok, else registrar will keep sending 401.
Thanks,
Amit

Hi All ,
I have some doubts . Below Registration flow.
1. Register ( Register, To, From-tag=abcd Call_ID=xyz, Cseq=1 Register)
2. 401 Unauthorized ( To-tag=1234, From-tag=abcd Call_ID=xyz, Cseq=1
Register)
3. Register ( Register , To, From tag=abcd, Call_ID=xyz, Cseq=2
Register)
I would like to know the What is difference between two Register(1 and 3)
..Why Cseq is difference even though there is no change in Call_ID.?
Why 2nd Register does not contain the to- tag,where is the both the
Register Request contain same call id
Please clarify the doubts .
Thanks in Advance ....
