This router is completely broken, it will never function since the
router has no way to relate the RTP stream from * to external to the
correct external host unless it has a really good SIP helper (one that
actually works instead of just breaking more stuff :)

But I guess you should have atleast 1 audio leg working if you call an
internal phone (with canreinvite=no). That isn't the case?

This has to be a configuration error, you'll have to get in touch with
the admin to setup NAT routing without rewriting the external
adress/port.
