asterisk users - Mar 2005 - SIP callid

Hello all,

I tried the dev list, but got no answer at all.

I'm facing some problems with call-id generation in a
heavily loaded Asterisk Server. 

Asterisk is generating same call-id and from tag for
different calls (and this is not desirable). 

Looking at the source code I noticed that rand() is
used four times to get a callid. Is that safe enough?

Maybe my system lacks of a good random number
generator. Is that possible? What is necessary for a
linux box (Debian, in my case) to achieve good random
numbers (and consequently "good" callids)?  

Best Regards,

Chuck.

RAND(3)                   OpenBSD Programmer's Manual                 
RAND(3)

NAME
     rand, srand - bad random number generator
...

Is there some reason asterisk can't just read some bytes out of
/dev/urandom?
