Call2Teams - Customers
End users may be used to having several DDI lines assigned to them as offered by their PBX.
However, if there is no PBX present and users are assigned DDIs directly from a SIP trunk service, then there is no 'system' behind this that can provide the functionality.
As the service mainly uses the features that are passed through to it from the customer's systems, there is a limit to the functionality that the service can provide in this aspect.
Customers are advised to use multiple resource accounts in Teams to forward calls to the desired destination - the end user.
