Hello @Preston

Please note that this is currently not possible through the PBX. I would recommend however using a supported provider to avoid compatibility issues. You can find a list of supported providers here: https://www.3cx.com/partners/sip-trunks/

Hello @YiannisH_3CX

The system does support. The provider has shared with me traces showing other 3CX PABX support the feature.
