I have 5 phones in our NOC that all have the same four numbers. I would like to figure out the BLF so they can tell when someone is on say line 1

I am trying to get lines that are on multiple SPA's to show when in use, when on a call. I am using SPA 525's and 514's.  Thanks

I am trying to use our GIC service with SPA 525 phones and it looks like the phone is stripping the leading # off when I dial # and the GIC number. Has anyone else ran into this?

                   I would like to know the options to add a SPA500S addon to the SPA514G phone. I am running these phones off a DMS500 CS2K switch.

                   I have many SPA525g and 514G phones that I need the same line appearance on. I would like to see that if one person picks up the line that on the other phones it shows that it is in use. How do I do this?
