Vertical Service Activation Codes
The following Vertical Service Activation Codes are automatically appended to
the dial plan.
Call Back Delay
Delay after receiving the first SIP 18x response before
declaring the remote end is ringing. If a busy response
is received during this time, the IP phone still considers
the call as failed and keeps on retrying.
Defaults to 0.5.
Interdigit Long Timer
Long timeout between entering digits when dialing.
The interdigit timer values are used as defaults when
dialing. The Interdigit_Long_Timer is used after any one
digit, if all valid matching sequences in the dial plan are
incomplete as dialed. Range: 0–64 seconds.
Defaults to 10.
Interdigit Short Timer
Short timeout between entering digits when dialing.
The Interdigit_Short_Timer is used after any one digit, if
at least one matching sequence is complete as dialed,
but more dialed digits would match other as yet
incomplete sequences. Range: 0–64 seconds.
Defaults to 3.
