Not Receice Calls (486 Busy)


#1

I have DP750-720 (FW 1.0.13.0) on Issabel PBX (asterisk 13)
It does normally Register
External calls works fine

Μy problem is that i can’t get incoming calls

Called SIP/103
– Connected line update to SIP/105-0000000a prevented.
– Got SIP response 486 “Busy Here” back from 192.168.1.103:8060
– SIP/103-0000000b is busy
== Everyone is busy/congested at this time

Sounds like DND is on

Bug, another fix in beta, maybe this time it will work.


#4

Solved with hard reset DP720
Disappear DND icon
Before reset icon it was stuck

Thnks

There is a setting under handset LCD -> Preferences -> Mute as DND. After you configure it to “Enabled”, you will be able to use the “Mute” button to turn DND on and off. I guess this setting was set to Disabled after you accidentally enabled the DND, so you cannot turn if off again. I will suggest our SW team to just turn off the DND when the Mute as DND option is disabled.
