I was trying to prevent SRST GW from registering E.164 address to GK with 'dialplan-pattern' command under Call-manager-fallback with 'no-reg' parameter, but failed. It still registers.
I am using 10 digit ext. in CCM. So I configure:
dialplan-pattern 1 T extension-length 10 no-reg
I really do not understand why it does not work. Is there any other way to turn off e.164 registering?
Thanks for your help.
