[Freeswitch-users] Multiple SIP-registrations and leg-specific variables.

Thanks, but that's not going to do what I need. My example wasn't clear 
on that at all!

Let me try again...

i.e my bridge string has something like this in it:

{you_are_tenant=0024}[you_are_ext=312,leg_timeout=15]${sofia_contact(0024312)}, 
[you_are_ext=313,leg_timeout=20]${sofia_contact(0024313)}, 
[you_are_ext=314,leg_timeout=25]${sofia_contact(0024314)}

We have two classes of channel variable here:

{} eg you_are_tenant - which applies to ALL outbound legs
[] eg you_are_ext - which applies individually to each user login on a 
particular extension

If 312 has more than one SIP phone logged in, the expansion is to

{you_are_tenant=0024}[you_are_ext=312,leg_timeout=15]<312handset_1>,<312handset_2> 
[you_are_ext=313,leg_timeout=20]<313handset_1>, 
[you_are_ext=314,leg_timeout=25]<314handset_1>

And the leg_timeout on the call to <312handset_2> will be the default.

Is that better?!

BTW, this is somewhat academic now!
