[Kamailio-Users] How to prevent - Same username used on multiple sip phones

[Daniel-Constantin Mierla]

Hello,

I just added to svn a new function for registrar module: 
uunregister(domain, uri), see commit:

http://openser.svn.sourceforge.net/viewvc/openser?view=rev&revision=5010

The patch is small and clean. Backport to 1.4.1 should be straightforward.

This function should help you to achieve the desired behavior: if 
register has expires > 0 then call first

unregister("location", "$tu");

then

save("location");

The unregister() function removes all contact associated with the 
address in parameter 'uri'.

I am looking also to actually enhance save() function to get a 
functionality like:
- update the expires if there is a record with same contact
- otherwise remove all existing contact and add a new one

Perhaps would be a bit better than unregister()/save() sequence, but i 
see usages for unregister() function alone as well, and it is a small 
piece of code.

Could you please test and see if works ok for you, I had limited time 
for testing it, but I saw big discussion around this features and the 
effort to develop unregister() was low. Thanks you!

Cheers,
Daniel
