Network Design as follows -
â¢ Individual branches dial and establish a connection to the Central Location; in case of its primary leased line failure between the Branch and Central Location.
â¢ Central Location dials and establishes a connection to the Data Center. in case of its primary leased line failure between the Central Location and Data Center.
â¢ All branches are spread across the Country and have been activated with STD calling (Interstate dialing / calling).
Problem facing -
â¢ One of the Branch with 2801 Router+2BRI S/T card + 12.4(3B) IOS dials and establishes connection to the Data Center which is located in a different state successfully.
â¢ But this above branch does not dials a test call to its Central Location; which is again located in a different state. (Point to be noted: "STD Dialing is activated on this Branch, that's why it is able to make a call to the Data Center successfully, but fails making a call to the Central Location *01202775453*").
Can any one please HELP me to rectify this issue.
Please find the attached Debug q931 & q921 output of the Branch router when dailed *01202775453* and fails.
