sip-in: default use-100rel to no BulkVS servers act badly when we send a reliable 180 Ringing response to an incoming call, even though they advertise 100rel support in the Supported header in the INVITE packet, and we probably won't be implementing 100rel for outbound because doing per-the-spec PRACK as a UAC is just too burdensome. Therefore, we need to consider 100rel extension as not-really-supported in themwi-system-sw.

/*
 * In this module we implement the sending of MNCC_DISC_REQ,
 * signaling a caller-requested disconnect aka hang-up.
 * It is the graceful way of signaling disconnect,
 * as opposed to simply killing the test call process with ^C
 * and letting themwi-mncc handle the broken socket.
