I have an issue with an Aastra 57i CT SIP phone running firmware 2.0.1.1055.
Whenever I’m on an active call and I press the * button on the phones keypad it drops the connection.
I’ve tried down grading the firmware on the phone to an earlier version etc., Still the same issue.
Not sure if it’s the phone that’s the problem or Asterisk FreePBX?
If anyone else has a Aastra 57i CT SIP phone working with Asterisk FreePBX I’d be interested to know if you to have the same problem.
I’ve worked with Support at Aastra but they don’t seem to have any clue whats causing this…
