I'm currently using the Obi 110 with GV and it works nicely. That is my SP1 setup. For Obi SP2 I have a VOIPo connection since it provides 911 service. I have two Panasonic DECT 6 systems. The Obi/GV is linked to one and the VOIPo Grandstream box is linked to the second set. Everything works fine except when someone calls me using the VOIPo #, both phones ring rather than just the VOIPo one. What do I need to do to stop this? If I didn't need to use VOIPo for its 911 capability I could just remove it as the SP2 on the Obi but I would prefer to not do that. The reason for the two sets of phones is because one is basically used for my home business while the other is a home land line. I want to be able to receive or make calls on either phone without the other phone being involved, if possible, although I realize I couldn't make a 911 call on the Obi/GV line while talking on the VOIPo line..
Any advice as which systems controls would take care of this; Obi, GV, or VOIPo?
