Hi all, I'm doing some test registering a sip terminal to OCS 2007 server. I'm using both epid and +sip.instance header as indicated in [MS-SIPRE] (Session Initiation Protocol (SIP) Routing Extensions).
The server answeer is always "SIP/2.0 400 Mismatched epid and +sip.instance header parameter values".
I followed the [MS-SIPRE] 3.2 chapter using the UUID "fcacfb03-8a73-46ef-91b1-e5ebeeaba4fe" as namespace ID.
Then I executed UUID utility from a linux system:
UUID -v5 fcacfb03-8a73-46ef-91b1-e5ebeeaba4fe 1122334455
obtaining the UUID af0938d4-d82e-5130-aece-9a97f909fe61.
Using af0938d4-d82e-5130-aece-9a97f909fe61 as sip.instance and 1122334455 I obtain the Mismatched epid and +sip.instance messagge. Instead using the values taken from a Office Communicator capture all work fine.
What's the correct procedure to generate the UUID in a EPID namespace?
Any help is appreciated.
Thanks in advance.
