Manage Next-Gen SIP Trunks
Next-Gen SIP Trunking
The following information applies only to SIP Trunking accounts created on Cymbus's Next-Gen platform after January 2024. If you aren't sure whether this applies to you, contact Customer Support for assistance.
To manage your SIP trunks, log in to the Admin Portal and go to Account > SIP Trunk. From here, select an existing trunk to view or modify the settings.
Here you can configure the SIP trunk settings, including forwarding, overflow and failover routing, concurrent call limits, and calling plans.

911 Callback Number | The phone number and address that emergency services will be given when a call comes in from the given SIP trunk. All phone numbers that call emergency services via this SIP trunk will have this phone number and address. Only one phone number and address can be assigned to a given SIP trunk. |

In capacity exceeded scenarios, calls being routed to other SIP trunks will not follow the other SIP trunk's failover routing configuration.
