Customer moved and service provider delivered loop start lines instead of ground. We requested the ground start lines and now we are screwed. The building has facility issues and we recieved only analog lines which were delivered on a 1 to 4 multiplex service..... I did change my trunks to LOP start and can make calls out but am unable to get the MM to answer the calls.... is there anybody that uses LOP who has had success????? I have already told the customer that problems are very likely to occur and they understand.... I am going to look into the loop to ground converters, but until then,,,, any suggestions....?????? Thanks !!!!!!!!!
