Chapter 3 - Using the Web Configuration Server
Using supplemental external services (Example 3):
When a soft switch or a SIP server/gatekeeper exists in the network and the user
would like to use class 5 services which are not internal to the Voice Gateway e.g.,
*xy#, *xy*abcd#, #xy#, etc., the VG dialplan should be configured as follows:
[*#][0-9*][0-9*].#
Note that when VG internal class 5 services are enabled (default) in addition to the
above dialplan, the internal class 5 activation codes remain valid. See Appendix A.
Call completion
Call completion means allowing user to skip the timer period T after finished
dialing, by ending number sequence with '#' (no other character is valid for this
feature). A valid dialplan to accomplish this would be: (xx.#|xx.T)
3.7.7.1 Hotline
The hotline function allows a predetermined number to be called automatically by
waiting T seconds (which can also be configured) without pressing any keys.
The hotline function can also be used to receive tones from the Local Exchange.
This is achieved by leaving the number in the hotline dialplan empty. Additional
modifications may be required, in which case, contact Customer Support for
assistance.
The hotline feature is activated by specifying "T" (time-out) in the dialplan (by
default, T is set to 4 seconds).
For example: (xx.#|xx.T|<:1234>T)
The number 1234 will be dialed after T seconds.
3.7.7.2 Adding/Removing Prefixes
For outgoing calls
VG can add a pre-defined prefix to a dialed number via the dialplan and send the
number with the added prefix to the server. The prefix can automatically replace a
dialed digit using the following notation:
"<'dialed substring':'transmitted-string'>"
For example:
Set the dialplan to "<8:1860>xxx"
When dialing 8123, the digit 8 is replaced with 1860, and the actual number sent
is 1860123.
