Not sure if this is still an issue for anyone else, but I hit it face first tonight. I had set up the CME, and allowed it to auto configure the ephones as part of the telephony-service setup process. Increasing the max-ephone parameters didn't do anything.
My phones kept being rejected at registration. What was showing up in the config was this:
ephone 1
no multicast-moh
mac-address 0012.433D.D50F
keepalive 30 auxiliary 0
type 7940
button 1:1
I blew away ephone 1 and then rebooted the phone. This time it registered and came up. But the config now looks like this:
ephone 1
mac-address 0012.433D.D50F
type 7940
button 1:1
I went into the CLI and tried the other two commands that weren't there. Adding back in the no multicase-moh and rebooting the phone didn't cause any problems
But, it wasn't possible to add in the other command:
keepalive 30 auxiliary 0
IOS reports that the valid values for auxiliary are 1 - 65535
Apparently the setup utility creates an invalid value for this (which might have been legal under previous versions...I don't know).
I added in the command as:
keepalive 30 auxiliary 1
and the phone can register (although I'm not certain of the effect setting it this low).
Setting it to:
keepalive 30
also works.
Hope this helps someone else.
