When I reset a previously registered phone in a IOS Telephony Service environment (either via the reset or restart command or the **#** sequence) the IP Phone is unable to re-register unless I reload the router. When I type a show ephone, the status of the phone is UNREGISTERED.
The router Im using is a 1760 and Im running 122-15.T1 (Ive tried different IOS levels with no luck). The problem is the same with any IP Phone model, 7960, 7940 or 7910.
Has anyone had the same problem that I have with the registration of IP Phones on ITS? Any help is appreciated.
There is no output on the "debug ephone registration" command related to that problem whatsoever. What is interesting though is that if I do a "sh ip dhcp bindings", I don't see the entry of the IP Phone with problems; It seems like the IP Phone cannot get the IP address from the DHCP server. This issue points that the problem may be on the DHCP server side rather that on the ITS. The message that appears in the IP Phone is "Configuring IP". Let me know if there's something specific (besides the 150 option) required on the dhcpd process. I posted the running-config on another message.

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
