Transfer a call after answered to an external phone number

I am wondering if the service will let me tranfer a call after I answer it to an external phone number. Example is someone calls in I answer it and need to transfer to a 3rd party business? The android softphone I’m using says it will accept it if the service allows it.

Yes It is possible to transfer out to regular phone number destinations, however, there is no possibility to dial external SIP destinations.

Thanks and here if you need anything else
