For a complete list of supported SIP trunk providers, refer to Portal configuration for PSTN SIP trunks .
An external SIP trunk can only be configured with a single SIP trunk added in the StarLeaf Portal. Entering the same Gateway and Extension authentication of an external SIP trunk to multiple SIP trunks in the StarLeaf Portal, will cause the configuration to fail.
If you want to have multiple SIP trunks configured to a single SIP trunk provider, you must purchase more SIP trunks from that external provider.
