Description
Use the sk_setGroupHandler() function to complement the function sk_watchChannelGroup(). When a message arrives on a channel that does not have an explicitly-assigned handler function, the handler function of its group is notified.

int sk_setGroupHandler(char *aChannelGroupName, void *aTag, HandlerFunc* aHandlerFunc);
Threadsafe Syntax
int skts_setGroupHandler(char *aChannelGroupName, void *aTag, HandlerFunc* aHandlerFunc);

aChannelGroupName |

How sk_setGroupHandler works
Send the following function calls, with respect to your naming convention, to the LLC:
sk_watchChannelGroup("inbound");
sk_setGroupHandler("inbound", NULL, handleInboundCall);
After this function call is sent and if your application uses sk_rcvAndDispatch() or sk_rcvAndDispatchAutoStorage(), every time a message is received for a channel in the specified group, the message will be sent to this handler function.
Always returns OK.
