[cisco-voip] SRST survives after router reload/reboot

[Erick Bergquist]

And if you do that, and don't reboot for awhile... you may not find it until the router reboots for some reason at an inconvenient time and calls are not working due to the command missing. Then you got to figure out what happened and fix it while people ask why calls are not working.

I have also seen this command get removed from the D channel interface on it's own out of blue when the T1 and/or MGCP flapped in some IOS versions or the command wasn't restored correctly after MGCP came out of MGCP Fallback mode. 

But this has more to do with MGCP Fallback and not SRST... the two occur at same time if on MGCP gateway with SRST but are different functions.

one of the things you'll find if you write the config while in SRST is 
that with an MGCP PRI, the isdn bind-l3 ccm-manager command will be 
removed from the serial interface so the PRI can fall back into q931 
mode. If you write it while in SRST, you will write the serial 
interface without that command in it. Normally the command is restored 
after normal operation resumes..
