Call Control Function
3.10 Protocol-Specific Parameters
(Page 11 of 12 in this chapter)
- This section describes protocol specific parameters that have a direct effect on the
call control events and functions. For a complete list of parameters, refer to
Appendix D in the AG Access Function Reference Manual.
3.10.1 Loop-Start Parameters
- The following loop-start parameters are contained in the ADILPS parameter
structure.
- numrings - The incoming call event for loop-start protocols is configured by
numrings. If this parameter is 0, the event is generated on the leading edge of the
first ring tone. Otherwise, the event is generated on the trailing edge of the ring
specified by numrings. Note that if caller ID is enabled, there will always be at
least one ring before the incoming call is reported.
- nodialtoneaction - Defines behavior when no dial tone is present.
- xfersupport - This flag indicates whether PBX transfer functions are supported.
- cidsupport - This flag indicates whether caller ID is supported.
Loop-Start Glare
- When placing calls on loop-start lines, glare is detected by the absence of dial tone
which is handled in the following manner:
3.10.2 Wink-Start and DID Parameters
- The following wink-start and DID parameters are contained in the ADIWNK and
ADIDID parameter structures, respectively.
- waitforPCtime - This parameter is the maximum time for the application to accept
or reject an incoming call. Failure to respond in this period causes AG Access to
automatically reject the call. The call will be rejected in the manner specified by
the defaulttone parameter.
- defaulttone - This parameter dictates the tone played when AG Access rejects
incoming calls due to application response timeout, according to the following
table:
