We have installed VitalPBX Communicator in order to test it. Our current configuration is as follow

  1. An extension named 200 has been created in the PBX at the tenant level

  2. The maximum contact number is 2

  4. Installed and configured VitalPBX Communicator

  5. We tested outbound calls on VitalPBX Communicator and it works as expected.

  6. We tested inbound calls to extension 200. The deskphone rings, the VitalPBX Communicator is not ringing at all.

Any idea why? Or can we point us to the documentation that could help us? We didn’t find any for VitalPBX 4.5.x and VitalPBX Communicator.

The device for extension is set to use a WebRTC Profile, which is wrong as communicator is not a WebRTC client, add a a new device with the default PJSIP profile or modify you current one if you are not using WebRTC and it should register properly.

hi Hlev,

Thank you for your help. We did try with PJSIP Profile as well and it didn’t work neither. Just to be sure, VitalPBX Communicator is registered but incoming call doesn’t ring it. Only the deskphone. Please note the screenshot below is with PJSIP profile selected.

Keep the device profile as PJSIP, log into your server console launch sngrep and get some logs of your calls to see what is happening.

Hi HLev.

We’ve trace the inbound calls through sngrep and here is what we see
image

  1. The first INVITE is the carrier (209.197.130.80) forwarding the call to the VitalPBX (142.93.155.35)

  2. The second INVITE is the PBX forwarding to the endpoint. If you notice, the destination endpoint is port 1253 which correspond to the Deskphone as in the updated screenshot below.

In sngrep, we never see any invite sent to port 1254…

Also, if you look at the screenshot, you do see the 2 endpoints on line 37 and 38 using respectively port 1254 and 1253.

Are we missing a configuration somewhere?

Hi HLev,

No need to help! Just realize that when pressing 200 at the IVR level, the latter record option 2 which rings line 101 rather than extension 200. We made some tweak to test it and it does work (ringing Deskphone & Softphone).

Our bad! I guess is the lack of experience with VitalPBX.
