    Hello Community,

    I´ve got a Problem with my 3cx,
    Internal calls are afected by the forwarding rules i configured in my status.
    But external calls cant conect to the number i configured.
    So I cant forward a call from a mobilephone to another one or another 3cx client.
    Is this a known Problem?
    Are there any solutions?

    We could use some more explanation of the issues.

    From what I gather, if an extension has a forwarding rule in-place and when a call is made to that extension and it comes time for the rule to be invoked, then if functions as it should. So, this does not seem to be a problem.

    However, when an external call comes in and is sent to an extension with a rule and it comes time for the rule to be invoked, it fails or does not follow the rule. This may be the result of how the rules were created. You did not mention if the same rule if In effect for both internal and external calls. What happens to the call?

    You also mentioned - "So I cant forward a call from a mobilephone to another one or another 3cx client". I am uncertain if this is related to the external call forwarding or another issue. Do I take it that "mobilephone" is really meant to be the 3CX softphone client? I get lost on "mobilephone to another one" and then you indicate "or".

    Have a look at, and/or post the 3CX log of one of the failing forwarded calls. It should show why the call fails. You do have an additional outgoing trunk for the external call to use...right?

    It may also be an issue with the forwarding number not matching outbound rules.

    Okay so here is a better Description of the Problem:
    When an extion calls another one with a forwarding rule it is forwarded as planed.
    But if I call an extension with a forwarding rule by an external device like a mobile phone
    The forwarding rule doesn`t work and the call gets terminated or send to the Voicemail.
    But if I call an extension without forwarding rule with an external device everything works just fine.

    The rule is inplace for internal and external calls,
    Yes I have an additional trunk for the external calls,
    The forwarding numbers match the outbound rules

    -> 250 is the internal extension, Outcall ID but in profile the 03 at the end

    -> 0123456781 is the phone number, which should be called with the forwarding
    -> 0987654321 is the number which is calling me

    The reason for the disconnect is not obvious other than to note that the call was terminated by a 487 code. This is a cancel which is usually indicated when something else has taken the call such as in a ring group or similar. Obviously, this is not the case here. I am uncertain if the log post was filtered on the extension or raw of all transactions occurring at the same time. If filtered, it could be that we are not seeing what else may have been a factor.

    It could also be that a wireshark might show more info as it is carries more detail and specifically more as it relates to the provider. One thing you should try is to enable PBX provides audio on the SIP trunk. In my version of 3CX (V14), when I create a trunk using the embedded Vofaphone (DE) template, I notice that PBX delivers audio is enabled by default.

    Could it be that the forwarding is attempting to send out a caller ID that is not permitted by your provider? Do they allow you to change, or even attempt to change that?

    If you call forward an extension, what caller ID does the called party receive?

    1. PBX delivers audio was checked
    1. wireshark on the Server or Client?

    The provider supports the following features, which are also unlocked. Under SIPGate there are the same problem.
    Inbound Clip – Yes
    Outbound Clip – Yes
    Multiple DIDs on one Trunk – Yes
    Clip No Screening – Yes
    Call Deflection – No

    I should have said...If you place a call from an extension, and that call follows the forwarding rule, what number shows on the called party display? Is it the "main" number you have been assigned by your provider, is it the extensions number, or DID number?

    Has your provider (or Wireshark) been able to provider any insight?
