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, -- ------------------------------------------------------------ Erick Perez ------------------------------------------------------------ -------------- next part -------------- An HTML attachment was scrubbed...

[asterisk-users] Asterisk 1.4 and Cisco Phones 7940
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. http://www.voip-info.org/wiki-Setup+SiP+on+7940+-+7960 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 -------------------------------------------------- Salvatore Giudice Salvatore.Giudice@VoIPSecurityTraining.com VoIP Security Training, LLC http://VoIPSecurityTraining.com 848 N.
