Extension Issues

[milworld]

So I have an extension that is running a Yealink T19P E2 the extension appeared to provision correctly without any issues.

I can make calls from the extension and all shows up correctly in the company directory.

However when I try and make a call TO the extension I get nothing, no ring tone it just diverts to voicemail. The extension is showing active (green light on the Extensions tab) but the phone will not ring and even picking the phone up doesn't connect the call.

Nothign is showing in the event log (no Warning, Error or Information)

System details below I hope someone can help with this

Cheers in advance

Hi @milworld,

When you say you try to make a call to the extension, do you mean internally (extension to extension) or via a DID pointed to that extension?

Is the Activity Log set to Verbose? If no, set it to Verbose and then try and make a call from a different extension logged in on the Web Client to the T19P's extension. What does the Activity log tell you? You can use the filter to filter down by extension for optimal information acquisition.

Hi
Yes extension to extension or even external to extension.

It appears to be an issue with the Yealink T19P E2 as when I load the extension up on another phone it works and receives incoming calls fine.

All logs show call as being OK except when using the YeaLink T19P E2 on that extension then its as tho the call never connects to the extension although it shows on the dashboard as connected.

Hi,

You are currently running in STUN, it's a common phenomenon to have issues with calls.

Your options are either to use an SBC, or do everything included in this guide which should alleviate the problem (no steps should be skipped - ensure all points have been met).
