I'm using a yealink SIP-T22P and trying to auto provision the same with Elastix. I used the help from http://www.voip-info.org/wiki/view/SIP-T28 to do auto provisioning, but since the models are different few variables seems to have mismatch. I also wanna know which variables to use in the <mac>.cfg file so that I can provision multiple SIP accounts (the example shows only one) on the phone. Since these phones support remote XML phone books, I wonder if I can use the asterisk phone book ? I tried surfing a lot on this topic but do not seem to be heading anywhere, any direction will be much appreciated. -thanks.
