[Asterisk-Users] Re: Any Ideas??? 3rd time posting => Sipura SIP Phones Multi-Line

[Steve Blair]

Steve:

  Most likely you haven't received a solid answer because the standards 
defining
this behavior are still developing. Features like monitor line and 
multi-line appearance
depend upon functionality in the phone set too. Vendors are implementing 
these
features in their products but in proprietary ways. Until the standards 
are ratified you
are pretty much dependent upon vendor specific extensions for these 
features.
