UHLL
In the past, pbxnsip offered a module connecting the PBX to property management systems (PMS), enabling features like billing international calls and notifying the front desk about room status updates. This functionality was based on the Universal Hospitality Language Layer (UHLL) protocol, which also supported non-telephony tasks within hotels. While this module was useful, it required additional software and added complexity. For the next release (5.2.5 or 5.3), we’ve integrated UHLL directly into the PBX code, simplifying the setup. Those interested in trying out the new features can email us for access to a beta build.
