Summary: Srand in b2b_entities

Initial Comment:
Hi,
The use of srand is wrong in generation of random value in the second part of callid.
srand have to be called one time for init, after call rand to get a random value.

Message:
Hi Olivier,

You are right, srand is not used right there.
However, we want to take out that part from there, not use srand anymore
and extend another mechanism for getting unique values that is now used for
top hiding, to other scenarios also. Now for top hiding the from_tag is
computed from 4 values taken from the message - callid, fromtag, ruri and
via branch.
I will implement this and take out the random from there next week.

Thanks and regards,
