[Asterisk-Users] ADSI phone vs. IP phone

[Dustin Goodwin]

Seems like you have experienced a few problems implementing this type of 
configuration. My first hand experiences have been more positive then 
yours. Could you share more with the list what went wrong?  Also IP 
phones connected to ports configured with Cisco portfast have never 
caused me any problems. What did you experience?
