Hi Brian,

Thanks for your reply - makes perfect sense - if it's Asterisk style 
**<multicall_number> on a key with a SUBSCRIBE to the same number on the 
phone. I am concerned that one of the phones actually would have to be 
registered to that extension to make it work, or is that not correct? 
This is why I was looking at SLA.

The other part of this is that the <multicall_number> must not go to 
voicemail or busy tone until capacity is reached, ie. all the people 
with the BLF button configured are busy. I tried this with 
TrixBox/Asterisk but as soon as one call was live all further calls to 
the same number gave voicemail or busy.

If both of the above work "just great" in FreeSwitch then you may well 
have found my solution.

I haven't attempted what you describe with FS as I don't have enough 
phones set up at the moment to do it, and I currently only have 1 
Grandstream GXP2000 (needs FreeSwitch code hacking for BLF to work even 
half-properly) and a shedload of Mitel (SIP Mode 5224/5324) where the 
BLF doesn't work at all. Softphones are not under consideration at 
present. I'm quite able to get a couple of Polycoms or Snoms but I'd 
need to justify the expense to management.
