Hi all,
The following phone numbers are examples only and repeat a pattern as required to show the problem.
This may require a knowing DMS 100 technician. I have a customer who repeatly gets calls from several schools in the same school board and each school is located within the same exchange (739). These schools have centrex service but I don't believe the use the feature of 4 digit dialing between schools. The customers number repeats the local exchange number for example 739-7399. In the school they have to dial 9 to dial outside of the centrex group and access the PSTN. If a teacher or student simply accesses an outside line directly for example line 2 and does not dial 9 first then the call is treated as a centrex call and should be routed if the number dialed is valid within the group. If the teacher/student starts dialing a local number such as 739-9XXX without dialing 9 first, the call is routed to 739-7399. As long as the first four digits dialed are 739-9 every call comes to him. That makes a possible 1000 numbers coming his way from the schools. The local telco has confirmed that his number 739-7399 is not a member of the centrex group and 7399 is not a valid number within the group but can do nothing to stop the calls.
I am hoping someone who has an intimate knowledge of the call processing within the switch can offer a solution as I believe the local telco can fix it but need a little direction.
I believe a work around could be programmed through the school switches but they do not want to pay for the technician.
