I have Several DX80s registered to CUCM 11.5. When they connect to CUCM they register with the phoneext@internaldomain.org. The device is connected to the users profile and can be dialed via their normal SIP address (their email). However, TMS list the unit as phoneext@internaldomain.org in the phonebooks. I would like to have the device be listed with either the users SIP (email) or phoneext@externaldomain.com. How do I fix that? When I manually change the SIP URI on the device It will not register with a 404 not found/not configured error in the DX80.
Any ideas on how to clean this up? Is this normal behavior?
Thanks!
