[Asterisk-Users] Snom 200 stuck on "Busy"

[Matt Lawson]

With a recent update  to Asterisk CVS, and versions 2.02r and t of the 
Snom 200 firmware,  I'm getting the Snom phones stuck reporting "Busy.":

    -- Got SIP response 486 "Busy Here" back from 10.12.34.248
    -- SIP/3064-b07d is busy

They're on-hook, not doing anything.  They are registered fine.  I can 
pick them up and call out over Zap or IAX fine.  I just can't call the 
extensions because they always report busy.

Has anyone else observed this?
