[cisco-voip] Keeping phones in SRST Mode

[Christopher M. Bomba]

Thanks, I was hoping to find a command similar to the "ccm-manager switchback" command.   

The ACL solution is a manual process and if I could create something that would monitor the link and if it stayed up for > 30 minutes then allow the phones to switchback.  What about a script of some sorts to put on the router? 

I guess since H.323 is Peer-to-Peer I don't have the ability to rely on something else monitoring the link. 

Chris

We want to prepare for something like this as well. The easiest thing to do 
would be to create an ACL at the main site (which would have the more 
stable) and simply prevent access to all your voip servers. You could 
simplify this with an alias that would copy a bunch of commands stored in a 
file to the running config. If you have numbered ACLs, it's even easier.
