Hello and thanks in advance for reading our request
We had a AS-5350 router which we used to connect Branches to HQ with dial-up, now we have it replaced with ISR-4431 router plus NIM-2CE1T1-PRI and PVDM4-64 modules for E1 connectivity.
But now Branch Routers receive busy tone while trying to dial the ISR-4431. if anyone have any suggestion to resolve our problem please inform us.
