Hi Pranab A Register request with '0' Contact bindings is equivalent to a Register request with 'no' Contact header. Such a Register request is typically used to fetch the current Contacts bindings for a particular AOR. See RFC 3261, Section 10.2.3
10.2.3 Fetching Bindings A success response to any REGISTER request contains the complete list of existing bindings, regardless of whether the request contained a Contact header field. If no Contact header field is present in a REGISTER request, the list of bindings is left unchanged.

Thanks in advance. thanks and regards pranab _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors =============================================================================== Please refer to http://www.aricent.com/legal/email_disclaimer.html for important disclosures regarding this electronic communication. =============================================================================== _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
