Read our guide on how to configure a SIP Trunk / VoIP Provider. This covers the generic steps required to configure a trunk with 3CX. Take note of the below special configuration requirements for Vodafone:
- Enter the main trunk number as E164.
- Choose between 2 supported Vodafone trunks: R3.b the basic trunk or R4.a which includes additional features: Connected Line Identification Restriction / Presentation (COLR/COLP) and 302 diversion.
