got a bad one. customer has about 9 medical clinics. during the day they seem to preform *72 on their own and go to the exchange. suddenly no calls come in until they dial *73. happens several times a day. at seveal locations. systems are sbx and sts. maybe half are sts. telepacific is the provider and says its the locations problem. we think we wouldnt have people doing the fwd in the middle of the work day at all locations everyday. they know better. and we dont think the ksus would go bad at the same time. i have never had this happen to any customer before. anyway today telepacific locked us out so we cant do a *72 as a test. so far about 6 hrs has gone by and no problem indicating it is on our end. can anyone make sence of this. thanks dave
