Another remote phone trouble call :-(

Customer has one IP phone they occasionally take home. It has been a couple months since they did this, and it connected fine to the 2100 in the office. Today the office manager took the IP phone home and got the dreaded "No SIP Server Found" message.

I went thru all the settings with her over the phone. The public IP at the office is still the same (they have a static and we checked it with whatismyip.com). Waiting now on their IT support people to check on things. She can remote into the office lan ok with her pc.
