Hi Vinessen,

What VoIP provider are you using?

 

[Vinessen]

Hello JohnS, im using BelgiumVOIP.
We bought 3CX from them.
Best regards,

I would suggest to run a capture on your system, and call your DID from an outside number.

Check the FROM: in your capture, and see what your provider sends to the PBX

From: "Customer Name" <sip:17770000000@callcentric.com:5060>

or

From: <sip:callcentric.com:5060>


See if the "Display name" or "User Part" is missing from those calls

Well I have great news to report. It seems our issue was because the "From" information was not being sent by or VoIP provider. Now they have corrected that for us PUSH is working on both Android and iPhone devices.

 

[Vinessen]

@OpenedBy Thanks for sharing that. I've asked my VOIP provider to check.

 

[OpenedBy]

@Vinessen You are welcome. If that doesn't prove to be the solution for you then the best option would be to open a support ticket with 3CX. Sadly it is a paid service at USD 75 per ticket. That's what I did. I am hoping the 3CX team can note somewhere in the public space that if the VoIP provider is not sending "From" data then PUSH will not work.

 

[Vinessen]

@OpenedBy Thanks dear.

Hi Vinessen,

The log shows what the PBX (127.0.0.1) sends to the phone, instead what you want to see is what the provider sends to the PBX. You can run a capture instead so you can see the provider invite towards your public ip
