The thresholds supported by Dialogic

 Global Call API for HMP are: 

QOSTYPE_JITTER

QOSTYPE_LOSTPACKETS

QOSTYPE_RTCPTIMEOUT

QOSTYPE_RTPTIMEOUT 

mode 

Must be set to EV_SYNC. 

Applications must include the gcipmlib.h header file before Dialogic

 Global Call API can be 

used to set or retrieve QoS threshold values. 

See 

, on page 264 for code examples.

This function is only supported in asynchronous mode. 

The gc_SetConfigData( ) function is used for a number of different purposes:

setting parameters for all board devices, including devices that are already open 

enabling and disabling unsolicited GCEV_EXTENSION events on a board device basis 

setting the type of DTMF support and the RFC 2833 payload type on a board device basis [not 
supported in 3PCC operating mode] 

setting T.38 fax server operating mode [not supported in 3PCC operating mode], which also 
enables/disables application access to re-INVITE requests 

masking and unmasking call state events on a line device basis 

Notes: 1. The gc_SetConfigData( ) function operates on board devices, that is, devices opened using 

gc_OpenEx( ) with :N_iptBx:P_IP in the devicename parameter. By its nature, a board device is 
multi-protocol, that is, it applies to both the H.323 and SIP protocols and is not directed to one 
specific protocol. You cannot open a board device (with :P_H323 or :P_SIP in the devicename 
parameter) to target a specific protocol. 

2. When using the gc_SetConfigData( ) function to set parameters, the parameter values apply to 

all board devices, including devices that are already open. The parameters can be overridden by 
specifying new values in the gc_SetUserInfo( ) function (on a per line device basis) or the 
gc_MakeCall( ) function (on a per call basis). 

3. Coder information can be specified for a device when using gc_SetConfigData( ), or when using 

gc_MakeCall( ) to make a call, or when using gc_AnswerCall( ) to answer a call. Note that this 
capability is not supported in 3PCC operating mode. 

4. Use gc_SetUserInfo( ) to set parameters on line devices.
