We have an LG Digital Key Telephone system model LKD30D. This was supplied and installed by CTI Commserve who I cannot locate, possibly out of business. We had a power blip and the system has become un programmed. We have 8 lines in - 2 x ISDN and now all incoming calls go to one extension. Can you advise us if there is a Bristol Company who could come to Wrington, Bristol to repair the system. Thanks Kenn Lloyd, Iwood Manor Wrington BS40 5NU telephone 01934 861174
