My system is connected to a PRI with a block of DIDs. I only want 1 TN sent as CLID for all outbound phone calls with the exception of the fax machines number. I went to the form DID Ranges for CPN Substitutions, entered my DID range and the TN I want sent in the CPN Substitution form. However, a different TN is being sent. It appears to be the billing TN. Could the service provider be overriding the TN I'm trying to sent on outound CLID or is their more programming I need to completed in order for it to work. I understand both could be true but if there's additional programming needed, please advise.
Thanks
