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

[Daniel-Constantin Mierla]

Hello,

moreover, the save() function can take now flag 0x04 in the second 
parameter to store and maintain only one contact per user:
http://www.kamailio.org/docs/modules/devel/registrar.html#id2506197

If you can test and report the results would be great.

Cheers,
Daniel
