PBX, will also enter the hook-off state to respond the
caller till it is ready for receiving the called number.
Default By default, analog E&M subscriber-lines select the immediate start mode.

Description This command is only applicable to analog E&M subscriber-line.
The start mode used for an analog E&M subscriber-line should be in consistency with
the PBX connected with it.
When using the immediate start mode, the numbers will not be correctly sent or
received due to the signaling type in some PBX, please modify start mode as the wink
or delay.
