Hi. I have a small percentage of desk phones not registering properly after an outage. Looking at rtmt -> cm -> device search -> phone -> unregistered phones I see that the status reason is DirectoryNumberMismatch.
Ive tried to find any relavent info but have come up empty. Older posts dont reaveal any clues and looking in the cisco docs doesnt hellp either since the phones are using SCCP. The different models affected are 7936, 7937, 7961, 7942. There are others of the same loads/model so its not the load. Ive tried reboots several times. Ive also checked the device/directory number configs and they are correct.
the error message seems to suggest this is SIP related, but you are running SCCP. have you look at your call manager trace files already to see if there is any info on why these phone do not register? Also, if you completely delete the phone, then add back in, does this register the phone?

Fixed my issues. For the desk phones had to get into whatever swtichport they were on and flipped POE on and off again. The conference phones had to be manually power cycled since they used non POE power. I guess the DirectoryNumberMismatch error was a red herring and resetting the phones through CUCM wasnt enough.
You should start by taking a packet capture from an IP phone and see if the phone is getting an IP first, then is it getting the config file through TFTP and then is it sending a Skinny register message to cucm. If you see the phone sending the packets fine then you need to take a parallel capture from cucm and see if any of those packets are being dropped over the wan link.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
