RFC does not mandate the particular algorithm to be used for the
generation of call-id .... You can use time in milisecond plus a five
digit random string followed by hostname for call-id generation. Do not
disclose any of your personal/server details in this process.

Subject: [SIPForum-discussion] Collision free Ids: Call-ID, icid-value,
Session-ID
Hi there!
Is there an approppriate algorithm like the 'Session-ID generation algorithm'
proposed in http://tools.ietf.org/html/draft-kaplan-sip-session-id-02,
for the Call-ID header and icid-value (P-Charging-Vector) param.
If
another developer attempts to generate an id (vis-a-vis the Call-ID
header and icid-value (P-Charging-Vector) param) using a different
algorithm than the one I've cooked up, I'll have collisions with
their ids, i.e. they will no longer be globally unique.
Is there an appendix with an algorithm in the specs for generating these ids
that I'm missing or is this a real problem?
