Inbound Rule "Forward to Outside Number" goes to voicemail after 20 seconds

[Plenar]

We have some employees that are permanently out of the office.

So we created an inbound rule for their DID with "Forward to Outside Number" and enter their mobile phone number.
On their mobile phones the voice mail is triggered after 30 seconds, but 3CX forwards the call probably after 20 seconds to the main voice mail number.
In the log file the status of the forwarded call has "No Answer".

How can I increase the time the "forward to outside number" rings prior to get in the status "not answered"?

Thanks,

Roland

If you were to increase the time to 30 seconds (the VM answer time, set on the mobile account), then the mobiles voicemail will answer the call. Is that what you are trying to achieve?

You might also look into the 3CX Call Rebound feature.

Yes, we want the voicemail of the mobile phone to answer the call, because often customers know the mobile number and call that directly. So there is only the mobile voicemail to check.

Unfortunately we cannot change the mobile voicemail delay, so it stays at 30 second. Therefore we have to change the delay on the 3CX. Actually I would even argue that an inbound rule should apply indefinite, so it should ring forever (at least 1 or 2 minutes) and never divert to a voice mail or another line.

As we have many technician, we do not want to set up a user everyone. Therefore, as far as I understood, the Call Rebound is not really an option.

Is there no way to change the standard delay on 3CX, or switch it off?

I know that the 20 second "limit" has come up before in the forum. I'm not aware of it being changed, unless that has happened in version 18.

There actually is no 20 second limit when forwarding a call outward directly from an Inbound Rule so it should ring enough to reach the 30 second timeout on the end destination. Is there any chance the call is actually being forwarded to an extension first, and that extension has a 20 second timeout on the 3CX Management Console?
