I have an ipo 500v2 R8.1 with two imcoming call groups. there are two issues that's bothering me. the first is the DID's for the analog faxes are not returning a busy signal when in use. the second call is just wavering in space. the other issue is I have two offices configured using the same T1 on the same IPO, office A is using route 0 and office B is using route 1. Office A hits the IPO almost immediately, but office B takes 14 to 20 seconds before hitting the IPO. can anyone help me figure out these issues please? The customer is concerned especially About the time delay of office B. Could this be a config issue or could it be the way Telco have the DID's configured on the T1?
