Description
First digit timer
If a subscriber does not dial any digit within the specified time by this parameter after
off-hook, the gateways will prompt to hang up with a busy tone.
The value must be an integer, and decimal points are not allowed.
Unit: Seconds; Default value: 15 seconds.
Interdigit timer
The maximum time interval to dial the next digit.
After timeout, the gateways will call out with the collected number.
The value must be an integer, and decimal points are not allowed.
Unit: Seconds; Default value: 5 seconds.
Complete entry
timer
The value must be an integer, and decimal points are not allowed.
Unit: second; Default value: 2 seconds.
This parameter is used with the "x.T" rule set in dialing rules. For example, there is
"021.T" in the dialing rules table. When a subscriber has dialed 021 and hasn’t dialed
the next number within a set time by this parameter (eg. 2 seconds), the gateways will
consider that the subscriber has ended dial-up and call out the dialed number 021.
Codec
Codecs supported by the deivce include G729A/20, PCMU/20 and PCMA/20. This
parameter must be set due to no default value. For details, see Table 2-6.
Several encoding methods can be configured in this item at the same time, separated
with "," in the middle; the gateways will negotiate with the platform in the order from
front to back when configuring the codec methods.
Hook-flash handle
The gateways provide the following processing modes after detecting hook flash from
subscriber terminals:
Internal: the hook flash event will be handled internally;
Server(RFC 2833): transmitting the hook flash to platform with RFC 2833;
Server (SIP INFO): transmitting the flash-off to platform with SIP INFO.
