Create a SIP Trunk with Routing User and Pseudo DID
When creating a SIP Trunk it is sometimes necessary to use a Routing User in order to maintain control over inbound calls in cases where the target of the SIP trunk is not available, or to use time frames. See here to learn more about using a Routing User with a SIP Trunk.
In these cases, it is helpful to route a pseudo-DID (a DID that is not routable over the PSTN) to the SIP Trunk in order to minimize cost and allow the Domain Manager (Office Manager scope) to retain control over the routing of the SIP Trunk.
A pseudo-DID will only exist in the PBX routing table and will not be visible in the Manage DID Inventory page.
Getting a Pseudo DID
You will be required to open a ticket with our Support Team to have a Pseudo DID generated. Please reference this article in your Support ticket. Our Support Team members will create a DID on your domain's inventory with a 1 replacing the first digit in the area code. For example, 1-646-663-7575 would be 1-146-663-7575. This ensures there are no routing conflicts on our platform.
Route Actual DID to the Routing User
The actual DID should be pointed to a routing user (and not to the SIP Trunk).
Use the Routing User to forward calls to the pseudo-DID
Edit the Answering Rules for the Routing User
The Routing User can now be used to forward calls to the SIP Trunk using the pseudo-DID
Because SIP Trunks can only be managed by a User with Reseller credentials, this method can be used to enable a PBX User with the Office Manager scope to effectively control routing to the SIP Trunk. The DID can be routed to any Pseudo-DID using all of the options available in the Answering Rules page.
