[Asterisk-Users] Multiple Line Appearances

[MLS Drop for SysAdmin]

Has anyone successfully implemented concurrent appearance of the same PBX 
extension on multiple SIP phones?

When using Cisco 7960s under call manager, you can have several phones with 
the same line appearance, but the first user to seize a line makes it 
inaccessible to other phones.

Under SIP operation it seems as though this is not possible, but we don't 
see group ringing definable for SIP extensions.

Thanks for your feedback
