Well, looks like the Asterisk team did not consider it a bug :-)  I kinda
think they are right and Asterisk is doing the right thing.  It's our ISP's
gateway that is not performing according to the RFC.

Only thing I can think of to try is to shove an SDP payload in the 488 message
and see if the other side honors it.
