Next, we have the SIP Settings under Settings > Technology Settings > SIP Settings. As mentioned previously, SIP is no longer supported officially and has been deprecated by Asterisk. These settings are here solely to support migrations from VitalPBX 3 to VitalPBX 4. This is in the case you had SIP extensions or trunks created with your VitalPBX 3 backup and restored in a VitalPBX 4 installation. This way, your backup can restored, and we recommend you migrate your extensions and trunks to PJSIP as soon as possible. Our Extensions Import/Export can help with this process, but Trunks need to be reconfigured from the ground up.
This module is mostly ignored by newer installations that start with VitalPBX 4 and will be removed in future versions of VitalPBX as this technology will no longer be available. No new SIP Devices and Trunks can be created. Rest assured that PJSIP is easy to adopt as it is backward compatible with any SIP device and SIP Trunk.
