Dial Code to Set Custom Forwarding Rule

[xirgo]

Hello,

We have some users that do not have access to the 3CX Windows Phone App or the iOS App however they would like to allow their users to set forwarding rules via their phone when they will be away from the office. Using the user web management console is also not an option.

Does 3CX have a Dial code that can allow users to enable call forwarding to a specific extension?

For example, Extension 101 would like to dial a dial code followed by the extension they would want all calls to be forwarded to.

Can this be done?

UPDATED

User dan_tx pointed out a fix
On all Yealink T4x and T2x units in order to have the forwarding feature from the phones work you must edit the provisioning template for the yealink phones.

Locate:

bw.feature_key_sync = 1

And replace it with:

bw.feature_key_sync = 0

Alternatively you can login to the phone's web console and go to Features, Select General Information, Look for Feature Key Synchronization and change it to disabled.

Once this is done the phone will begin to forward calls properly.

For more information please review the posts made by user @dan_tx in this thread!

I hope this information is useful to someone in the future!

What phones are you using? Many phones have the ability to do this rather than the PBX...
Forward all, Forward Busy, Forward Np Answer.

Yealink,

When attempting to use the Yealink forwarding feature it was not transferring the calls over. Have you tested this feature with Yealink and successfully use the built in feature?

 

[craigreilly]

I use fine with Grandstream phones. I have 1 T48 that I beta tested... so I just tried for you, and can not get it to work.

This is the same issue that I'm experiencing as well which is leading me to see if there is an alternative to accomplish the same thing via Dial code

Any other recommendations?

It was possible?

Of course, we could handle things on the pbx, but we would prefer, if users could configure things themselves on the phones, which saves admins time and is more convenient to everybody.

Hello there,

You can use the dial codes *3 to change status of the extension and forward the calls to another extension using the forwarding rules of the PBX.
You can also set them as BLF's and achieve this with a press of a button.
For example *31 will set your extension Away

This would work except it does not give the option for the user to set a custom forward to extension. What I mean by that is that we would be required to login to the management console and point the forward to rule when the user sets their status to away. It does not let the user for example to perform a *31#ext# where "ext" would be there the 3CX would forward their calls to when the away status was enabled.

As craigreilly mentioned with other phones you can simply set the feature on the phone to forward calls however with Yealink phones the forwarding feature does not work

I have also tested it on Snom phones and snom phones worked without any issues.

Mmmm, I got it to work on my T48G…

On the phone I press “Menu > Features > Call Forward > Always Forward”
Then set “Always Forward” to “On” and in the “Forward to:” field the extension number.
Save the settings and the phone forward all calls to the extension number you just filled in.

So far I've tried it on Yealinks T41, T46 and T26 and all do not work.

Which version of 3CX are you running? We are running version 15. I tested this on V15 Linux and V15 Windows versions. I also tested it on-prem and cloud hosted and all give the same results.

The Yealink phones all have the latest version of the firmware pushed by 3CX.

I also went into the Yealink Web page and made sure the settings were showing up there.

I also ran a syslog from the yealink phone to see review if there were anything being shown in the logs with no success.

Lastly I installed an older firmware on one of the yealinks to see if it may be a bug in the latest firmware and im still getting the same results

Not sure what else I could try at this point.

Do you have any phones other than the T48's that you could test this on?

I'm running v15 SP4 - Windows 10 Pro - on-premise

I'm too.

I have successfully tested with a W52P/W56P base and W52H/W56H handsets.
I don't have other Yealink phones here for test.

Did a wireshark on the 3cx server and testing this. The Yealink phone does not appear to be sending the 302 Moved Temporarily command back to the 3cx server. I don't know why. If I do a manual forward on an incoming call, it shows up in the wireshark and the forward works.

**Found Fix**

So did some googleing and found a yealink change log that mentioned not sending the 302 move when feature_key_sync was enabled. THey said the fix was to either disable that or add UseLocalFwd =1 to the config. Well adding to the config didnt work , probably because it is for a different model phone. However disable feature_key_sync fixed it, now the phone forwards as it should.

This was on a yealink t42g.

Hey Dan!

This is an amazing find.

Do you know if disabling feature_key_sync in the provisioning template for the Yealink models in question will cause any other issues?

I guess what im asking is what is the feature_key_sync exactly used for?

Thanks again!

Tested "Feature Key Synchronization" to DISABLED (by web) with Yealink T20 and working. I'll try with custom template.
