[asterisk-users] SLA Appearance between 2 Cisco 7960's (SIP)

[Aaron Daniel]

Speaking as someone who did an installation with quite a few Cisco 
phones running sip, they do not support hinting at all with the sip 
firmware.  The latest version of the Cisco phones (79x1) are primarily 
sip phones, however with the CCM specific extensions, they tend to be 
fairly difficult to get to work with asterisk.  I wouldn't recommend 
banging your head on the wall trying, took a while for the bump on my 
head to go away.  :)

Anyone trying to get this to work would be better off getting a phone 
that does support hinting, and has plenty of documentation on how to do 
it (Polycom, Aastra, SNOM, etc).
