Hi Guys,

I was thinking of adding a Valcom v-110rt to my 551B KSU but on line 5.. I really do not want to lose any of the 4 lines if I do not have to. Looking over the installation sheet for the Valcom v-110rt it looks like its possible to use the 5th line leads. I only have 2 phones now but I could have a total of 4 down the road. What I have in mind, install a mini 66 block and the Valcom v-110rt out side of the KSU on the side on the wall. Of course no room in the KSU....


What your thoughts on this and has anyone does this before on a 551 KSU who does not want to give up any of the 4 lines....

Thanks
