The 2N IP Verso is a security intercom that is highly scaled thanks to its modular design. The Helios Verso can not only be easily integrated into your current camera and monitoring system but thanks to programmable scripts, the whole system can be used as a security component to protect the building.

Our service is 100% compatible with Asterisk using either standard SIP registration or IP authentication where SIP trunks are configured as such. Asterisk is the base software behind many open-source PBX distributions, including FreePBX, Trixbox and Elastix, and is also the enabler behind many other ITSPs and commercial PABX manufacturers.

Please Note: Chan SIP is now deprecated in favor of PJSIP
