Editing Amazon Chime SDK Voice Connector settings

To finish setting up your Amazon Chime SDK Voice Connector, edit the settings from the Amazon Chime SDK console. Edit the termination and origination settings to allow outbound or inbound calls, or both.

Termination settings

Termination settings apply to outbound calls from your Voice Connector. Set up your calling plan and caller ID options here. You can also specify the IP addresses allowed to make outbound calls using your Voice Connector, and require credentials for making outbound calls to your Voice Connector. If you don't specify credentials, no authentication is required.


Your Outbound host name resolves to a set of IP addresses that may change as EC2 instances go in or out of service, so don’t cache records for longer than the DNS Time to Live interval. Caching for longer may result in call failures.

Origination settings

Origination settings apply to inbound calls to your Voice Connector. Here, configure inbound routes for your SIP hosts to receive inbound calls. Inbound calls are routed to hosts in your SIP infrastructure by the priority and weight you set for each host. Calls are routed in priority order first, with 1 the highest priority. If hosts are equal in priority, calls are distributed among them based on their relative weight.


Encryption-enabled Voice Connectors use TLS (TCP) protocol for all calls.
