We have 7841s at branch locations that obtain addresses and TFTP info via DHCP on our branch routers. They are 4321s running: Cisco IOS Software [Everest], ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 16.6.3, RELEASE SOFTWARE (fc8) Somet...

We have a few servers that have an IVR application that connects to a voice gateway via CAS T1s. I'm in the process of retiring a 2811 gateway and this is being moved over to our 4451. We are running CUCM 10.5 and the T1 is registered via MGCP. I've ...

I'm trying to use the following snmpset commands to send config changes to a 4321 that doesn't seem to have crypto keys generated for ssh. The file rtr-cfg.config just enables telnet. I know the commands work since I tested them on a different device...

Trying to figure out if the advisory cisco-sa-20180129-asa1 affects my ASAs. I have 5506-X running 9.8(2) running on them. The advisory says that this is fixed in 9.8.2.20. I do not see that version on Cisco's website. Only 9.8.2.

Is there a way to limit what users are allowed to register via Expressway? Currently as it stands, anyone who has valid AD creds in our domain could take a phone home or install the jabber app and get phone (CUCM, Unity), and IM services.

I know it's an old post but in case anyone else is curios, resetting the mgcp gateway in CUCM will restart the mgcp process on the gateway itself and drop all calls but phones themselves will NOT reregister.

This is ambiguous. If I have Jabber controlling a physical phone are the application dial rules considered? Or is it strictly if I'm only using jabber as a softphone (CSF)?

8 years later and you have saved me some headache my friend!! I had this exact same issue.

Joel Jackson · 06-05-2018

I reloaded the router afterhours and the issue seems to have gone away. Since that is the case it seems like this is an IOS bug. If it happens again I will contact Cisco via TAC. Strange that it would happen only at this one site. We have 40 other si...
