Title: Mitel 5000HX and external softphone configuration
Post by: robf on November 13, 2020, 11:01:59 AM

Hello all!  I am working on getting a SIP softphone working from outside our network.  We have a public IP for our Mitel and external IP phones can connect and function. 

I am using ExpressTalk as a test and can get it to connect and make/receive calls from within our network.  When I enter our public IP and attempt to register the softphone, I get a Failed 403: Forbidden error.  I verified port 5060 is open (Sonicwall) as this is the port ExpressTalk had as default.

Pretty sure this is a Firewall issue but want to make sure I am not missing anything else.

Any and all suggestions welcome.

Thank you!

Does it work from inside the firewall to the local IP of the phone system?

It does.  I am planning on opening up all ports for a few minutes as a test.

Still getting the same error after opening up all the ports.  Are there any other Windows softphone applications out there to try?  X-Lite is no longer supported with Bria being the replacement but they want you to setup an account with them.  And yes, I did setup an account and gave it a go.  Same results.

Thanks for your help!
