Here are some flows of a SIP & SCCP phone call. My purpose was to see is it really only digit-by-digit dialing even when the phone is on hook.
on-hook dialing : EnBloc
off-hook dialing : Digit by Digit
type B on-hook dialing no dial-rules : EnBloc
type B off-hook dialing no dial-rules : Digit by Digit with KPML event
Normal off-hook (Digit by Digit):
Normal on-hook : (Enbloc)
Delete a number while dialing, off hook :
Change number during dialing, on hookÂ :
off-hook normal dialing :
off-hook with BackSpace during dialing :
on-hook normal :
on-hook with BackSpace :
When you use a SIP phone with Dial-rules, it’s Enbloc !
- Type A SIP Phones: Cisco Unified IP Phone models 7905, 7912, 7940 and 7960
- Type B SIP Phones: Cisco IP Phone models 79×1, 79×2, 79×5, 7970 and 7960
Type A phones only support enbloc dialing when using SIP firmware.
