Dual ringtone when calling from webclient

[KjetilSorby]

We experience dual calltone on outbound calls when calling between different operators.
International tone generated by 3CX (brrr, brrr) and the regular progress tone, both at the same time.

Any clue why this accrue?

What version of 3CX are you using?

What phone and what template? Also what firmware version?

Hi!

V16 and V15.5

Dual calltone on outbound calls when calling between different operators only
occurs when calling from the webclient.

What do you mean "between operators only"? Does it do that when calling another extension or when dialing a SP?

My bad!

Calling external, like we using Telenor SIP Trunk and make a call til person or company that uses Telia or Phonect as their provider, then dual call tone occurs.

It does not happen when calling between extensions?

Is your provider an official supported one?

Calls between extensions is ok.

Telenor is supported.
Same thing happens if i call from a Phonect trunk (also supported) to another provider.

Telenor- Telenor = ok
Phonect - Phonect = ok
Telia - Telia= ok
Telenor- Phonect= dual ring tone
Phonect- telia= dual ring tone
Telenor - Telia= dual ring tone
and so on...

This happens only when a call is made between different providers and
only from the webclient.
All other phones, yealink, snom, windows phone client, Android client works fine.
