Hi Danny,

I do not know what you are doing wrong, but you could check the
following:

- Is Do-not-disturb possibly activated on the phone? (just checking)
- What does "sip show peers" say (in on-hook mode, is the phone
correctly registered to asterisk?)
- What does the CLI show when you call the phone from another
extensions, with "verbose" somewhere around 10?
- Might NAT have to do with it? Something special with the network
socket you use for the phone?
- You have a recent firmware on it, I guess. Better check that anyway.

Best regards
Anselm
