As a convenience to Global Call application developers, most Dialogic® IP Media Library API 
parameters that are set via the IPM_PARM_INFO data structure can be set using a Dialogic

®

 

Global Call API call. (The only IP Media Library parameters which cannot be set from Global Call 
are the three parameters for DTMF transfer mode and RFC2833 payload types.) 

The IP Media Library settings that can be performed for a line device from Global Call include the 
following:

enabling/disabling echo cancellation

specifying adaptive coefficients for echo cancellation

specifying the echo tail length for echo cancellation

adjusting audio volume level to or from the IP network

specifying the type of service in IPv4 headers, either as a 7-bit TOS field or as a 6-bit DSCP 
field for Differentiated Services (per RFC2474)

For more information on the IP Media Library parameters that can be set and the supported values 
for those parameters, see the reference pages for the IPM_PARM_INFO data structure in the 
Dialogic

 IP Media Library API Library Reference. 

To set an IP Media Library parameter for a line device from Global Call, the application first 
constructs an IPM_PARM_INFO data structure that contains the desired parameter ID and value. 
Then a parameter element containing the structure is inserted into a GC_PARM_BLK via the 
gc_util_insert_parm_ref( ) function using the following IDs:

IPSET_CONFIG

IPPARM_IPMPARM

Value = IPM_PARM_INFO data structure

The application then calls the gc_SetUserInfo( ) function to send the parameter block to the 
ipm_SetParm( ) function on a pass-through basis (that is, without any validity checking on the 
Global Call side).
