[SIPForum-discussion] sip Re-registration

[Srinivas .]

Darshan refer RFC 3261, section. 10.3 --> 7th point

 

For each address, the registrar then searches the list of

current bindings using the URI comparison rules. If the

binding does not exist, it is tentatively added. If the

binding does exist, the registrar checks the Call-ID value. If

the Call-ID value in the existing binding differs from the

Call-ID value in the request, the binding MUST be removed if

the expiration time is zero and updated otherwise. If they are

the same, the registrar compares the CSeq value. If the value

is higher than that of the existing binding, it MUST update or

remove the binding as above.
