Dear friends,
We are planning to setup an out of band management connectivity, in our test setup we have a Cisco 2811 ISR (with IOS 12.4(9)T5 ) with NM-8AM (Analog modem module) installed.
Test Setup:
1. One Analog line (PSTN) connected to PC via built-in modem
2. Second Analog line (PSTN) connected to Cisco 2811 (NM-8AM) terminated on the analog modem module
3. Both the analog lines are working fine.
Test Scenario:
1. The router should accept the incoming call from PC. And from the PC we should be able to telnet into the router via dial up connectivity (Out of band)
Test procedure:
1. The Cisco 2811 router is configured as follows:
version 12.4
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

2. With the above configuration, the router is not able to answer the incoming call from the PC.
3. And from the PC we are able to dial to a PSTN number at the router side, PC gives a proper dial tone and once the number is dialed, the call is landed on the other side (router end) and it rings continuously. But, the router does not answer this incoming. The analog line at the router end is terminated on async interface 1/0.
As I am new to dialup connectivity with NM-8AM, Could some please suggest the proper configuration in our router configuration OR Are missing any commands?
Any links/references would be of great help.
Thank you
Pradeep
