Call from doorbird to websocket endpoint fails

rebell21 · September 8, 2025, 1:01pm

I have a doorbird doorbell and I want to communicate using sip. asterisk provides the websocket. I can call the doorbird from openhab using the websocket provided by asterisk. But I can’t call openhab from the doorbird. My dialplan says to call the endpoints. But asterisk can not make an outgoing call to openhab.

Dialplan

exten => 6004,1,NoOp(Group call from Doorbird)
same => n,Dial(PJSIP/zoiper&PJSIP/notebook&PJSIP/webrtc_client,20)
same => n,Hangup()

here ist the message from asterisk cli

‘notebook’ and ‘zoiper’ are switched of. So these endpoints are not registered. But I only see this message from calling the webrtc_client.

    -- Called PJSIP/webrtc_client
  == Everyone is busy/congested at this time (3:0/1/2)

it looks as if the webrtc_client can not be called

what does this mean ? I don’t see any incoming call at openhab

jcolp · September 8, 2025, 1:46pm

Is it registered? Is it reachable?

rebell21 · September 8, 2025, 2:15pm

I don’t see the webrtc_client when I say “pjsip show registrations”. The websocket connection is open. Do I need an outbound registration für the webrtc_client endpoint ? How can I register it ?

jcolp · September 8, 2025, 2:16pm

It would be in “pjsip show contacts” or under the endpoint in “pjsip show endpoints”. If there is no Contact, or it is unreachable, then it can’t be called.

rebell21 · September 8, 2025, 2:19pm

this is my endpoint

Seems like you’re masking everything out. Maybe a 24 bit mask would work better?

david551 · September 8, 2025, 10:17pm

That’s a valid way of specifying an address, rather than a network, and looks right in this context.
