OK - beginning to get to the bottom of this...

The sofia_contact command WAS showing multiple registrations, it just that I (for some unknown reason) expected to see them on separate lines, whereas they're shown on the same line, comma delimited. My bad....

However, there is (or was!) another problem in that one of our FS boxes is running a slightly old version (FreeSWITCH Version 1.0.head (git-139bd07 2011-11-21 08-27-25 -0600)) in which it would appear that multiple-registrations really is/was broken. Might that be possible?

Either way, I am intending to upgrade that box overnight.

Trying to set up our Freeswitch boxes to support "a few" SIP registrations against individual accounts.

I've modified "internal.xml" to have <param name="multiple-registrations" value="true"/> but it doesn't seem to have had the desired effect.

If I 2 SIP phones registering against the same user, I have never seen more than one simultaneous registration (as evidenced by the "sofia_contact" command). However (and this really spooks me!) if I call the DDI associated with that account, sometimes both phones ring (and accepting the call on either will cause the other to stop ringing).
