Purchased a Trio 8800 System with Visual+ and Eagle Eye camera. Have set up Line1 as Skype for Business, Line2 as our internal SIP PBX. I was also told that we should be able to direct IP call our factory and connect with their Avaya LifeSize system. So far I haven't found any way I can dial an IP address. I can add a Line3 with a SIP endpoint, but our factory has multiple Avaya systems and we don't always want to connect to the same one.
Is this possible?
