[asterisk-users] Asterisk 1.4 and Cisco Phones 7940

[Salvatore Giudice]

The features you mentioned will work fine, but you'll need to also have to
maintain a tftp server to provision the phones and ensure a quick boot. In
my experience, the only annoying thing about sip loads on Cisco phones is
that they don't support sidecars for admin.

Make sure you remove any callmanager related info from your DHCP scope
before you deploy Asterisk if they previously had  a callmanager installed.
When completing these types of conversions, you run the risk of the phones
going to an unprovisioned state if they start trying to access a callmanager
that has been removed from the network. It sucks to get called back to a job
a few weeks later when the customer's phone gets whacked after it was
unplugged and rebooted.

 

 

Good luck

I have read the wiki and several other internet documents. Can anyone make a
comment as to what kind of functionality will you loose if you use Cisco
7940 phones with asterisk 1.4
things like: MWI, call transfer, conference,etc,etc. 
I have a customer with 6 of those phones that he like to use with the
asteirsk PBX.

thanks,
