Summary:                    [patch] Calls are not matched to correct peer when
using callbackextension parameter
Description: 
If there are a number of peers with different callbackextension parameters
the incoming calls are not matched to the right peers

for example with two peers as follows
[trunk1]
host=sip.myitsp.com
callbackextension=9991
...
[trunk2]
host=sip.myitsp.com
callbackextension=9992
...

incoming calls to 9991 and to 9992 are both matched to the peer for 9992

---------------------------------------------------------------------- 
I am bit concerned about hashing on IP. That will only solve a few of all
cases. If you register to a provider with separate reg and proxy servers,
you won't receive the call back from the IP address you had resolved to
when building the hash. Generating just a random hash is a better way, that
will work in more cases. 

Limiting on IP is what we use ACLs for, we should not mix that in this
algorithm.
