Calling from a StarLeaf endpoint to the public telephone network (PSTN)
Managing Cloud StarLeaf Cloud and traffic routing for administratorsLast updated March 3, 2017
- PSTN connectivity is a non-standard feature that can be enabled for StarLeaf organizations on a custom basis, in conjunction with a suitable PSTN SIP trunking provider. Your StarLeaf sales contact will be able to give you more information about this, including any setup and monthly recurring costs involved
- When this feature is set up, a SIP trunk is actively registered from the organization’s StarLeaf call controller to the gateway of the PSTN SIP trunking provider. Calls made from StarLeaf endpoints to telephone numbers are routed from the call controller to the SIP provider, via the border controller and using SIP signaling over the Internet
- The provider completes the call to the telephone number and media is routed as shown in the diagram below
- Calls between StarLeaf endpoints and publicly-accessible SIP video systems work in the same way
