Would require a new option to let you set that. That being said, this is a negotiated setting, us sending 0-16 shouldn¡¯t cause anything to fail. If its failing the call because of that, that seems to me to be a problem they should correct on their switch. Its really strange to see this required on the sending side.<br>
