I have a situation where my "internal" phones can call each other,

Ok, it was a long night, it's almost 1am here, but I have figured this
out. I was creating my dialog with
create_dialog("pPB")
what was happening is that the pinger was trying to ping both an IPv6
address, and an IPv4 address... and probably reusing a socket where it
wasn't able to ping the ipv4 address... so it timed out and killed the
call from the middle right at 30 or so seconds.
By creating my dialog as
create_dialog()
without the pinging... the call continues just fine.
It seems that this "bug" is triggered where I have an outgoing call that
forwards to asterisk, asterisk then starts a new call by contacting the
proxy at its IPv6 address... and the proxy then needs to ping both ipv4
and ipv6 addresses.
the pinger should somehow decide which socket to ping over based on the
address family it needs to ping...
