/* The following is JUST GROSS!! There is some soft of underlying problem,
probably in channel_iax2.c, that causes an IAX2 connection to sometimes
stop transmitting randomly. We have been working for weeks to try to
locate it and fix it, but to no avail We finally decided to put our
tail between our legs, and just make the radio system re-connect upon
network failure. This just shouldnt have to be done. For normal operation,
