As somebody already pointed out (and I corrected this in the Wiki a
few days ago), IAX uses UDP, so plain ssh tunneling won't work.

The 5036 port is hardcoded in the IAX library (iax.h, #define
IAX_DEFAULT_PORTNO 5036) which gnophone uses. For the quickest hack,
change the value and recompile libiax.

In the longer run, consider adding a command line option (or even
better, a GUI config item), specifying an int passed to iax_init() in
pc_init() in phonecore.c in gnophone source (I went through the code
so much I almost know it by heart ;). Currently it is passed a zero
which means "the default". In any case, if the required port is in
use, IAX uses a random one.
