We are a Digium phone shop (dozens of D45-D70 sets) that is testing out a new D65 set. The set that we have seems to work perfectly (registration, receiving calls, contacts, BLFs, etc.), but it will not dial out. As far as I have been able to determine, no INVITE is being sent to our PBX when dialing is attempted. The set times out after a while with a “Failed” message on the screen. We are using the latest Asterisk, firmware, and DPMA versions. With the exception of the firmware, the programming setup is the same that we use with sets such as our D50s.
Is there something different about the new phone sets that needs to be changed in programming to get them to work? Any help would be appreciated.
