Bluesip.net uses "Sip EXpress router (0.9.7 (i386/linux))" and on client registration it returns "SIP/2.0 403 Max Registrations per IP exceeded" due to some bug/error/failure in the version 1.4 Acrobits Business softphone user-agent to unregister correctly.

Strange is that this never happens with accounts on AG Projects, "OpenSIPS (1.4.5-notls (x86_64/linux))" server. This server software seems to remove old registrations for the same user-agent from the same ip address.

What should be changed in Sip EXpress router, to store only one single registration per user-agent/IP combination?
