I've got my ATA's setup with DHCP, host=3Ddynamic, and turned the registration on in the ATA All is well as long as my sip.conf is configured using the phone number like so... [1231231234] type=friend host=dynamic context=main canreinvite=no username=1231231234 secret=worknow disallow=all allow=ulaw allow=alaw It appears to me that the Cisco ATA (v3.1) will register the device using the phone number only, even though you can change the authentication username, it always uses the phone number (UID0:) This forces me to use this as my configuration for that unit in the sip.conf [phone number] Is there anyway around this, or to force the ATA to register with it's mac address, or something i can do in asterisk, or is this just the way it works, and everyone else is doing this...
