Unable connect 3CX mobile apps and via Yealink phones

[perez.koh]

Hi,

We are having issues with 3CX mobile apps and via Yealink phones. web-based 3CX is working from a desktop,
May I check what could be the reasons for the same?
Also, getting errors in the log as below

Call or Registration to 87233349@(Ln.10000@MyRepublic Limited) has failed. 103.7.203.7 replied: 403 Forbidden [Call processing released]; from IP:103.7.203.7:5060


Can anyone help to explain this?

Thank you.

That appears to be your SIP trunking provider refusing your calls. You want to talk to them.

Hi @perez.koh


I don't think its a device issue but just in case run a few tests to make sure everything is working.
From devices that you are experiencing the issue try dialing *777 and see if you can hear your self talk.
Also make a few calls between extensions and see if those work. If everything works then its probably an issue with outbound calls in which case you will want to check that you are dialing the same number and that all calls are going out from the same outbound rule.

It may be one of two things... the number sent is not in the correct format, or, the caller ID is not acceptable.
