I have only seen this problem with several video conferences from one location. Currently there is only one T1 connection from our HQ to remote location. When two conference calls are set to use 256Kbps connection to come back to the main HQ, after an hour or so the T1 connection would drop. What I mean about drop is that the route on the 2911 will disappear. I have to wait about 10 minutes for the connection to come back up or I have to reboot the router for the connection to appear again. There are no interface drops on the serial connections or ethernet connections.
HQ - 2911
Remote - 1821
2911 running config:
Dumb question, but which IOS would I need...currently the IOS installed on the 2911 is:
Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.0(1)M4
What is listed on the IOS download is this:
If it still happens, take some show ip route to prove your observation.
Would I just download the Universial and not the Universal - No Payload Encryption?
Ok, when I also do a sh flash command, I notice:
-#- --length-- -----date/time------ path

If I run the "erase flash" command, will all of these packages get deleted? If so, can someone point me to the documentation on the correct command to run before running copy tftp flash?
This link prvides the IOS upgarde procedure for 2900 series IOS15.0:
I hope it works for you, the original link required partner login and I do not know if you have that.
Anyway, that link is:
If you never did an IOS update before, and/or never did network troubleshooting, configuration, etc. I strongly recommend you hire a reputable professional for the task.
No need to hire anyone . I was able to do the IOS upgrade on another 2911 I have for another purpose. It was straight forward after saving the old IOS config and running/startup configs. Kept the M4 bin in flash/flash0 and rebooted with the M7 flash. I will do the router with the issue Thursday and test/post results of the video conferencing.
