Hi,

I would like to use a Alcatel Temporis IP 800 and was wondering if this phone can indicate busy line with Asterisk?  
In the description of the phone it is said, that it supports BLF but I am not sure if this works with Astrisk or if BLF in the context of Alcatel means that it is only available with a Alcatel PBX.

Thanks in advance

In the meantime I figured out by myself that it works with the mentioned phone.
