[Serusers] multiple SIPURA behind same NAT

If I had a guess I would say either the NAT or rtp/media proxy is
getting confused about which client is which. Ignoring the problem for a
second, can both sipura's make calls at the same time? Are you using
NAThelper for this with SER? You mentioned "without proxy", this would
mean port forwarding? Try this, make each sipura use a diff range of RTP
ports (in their config).

	Dear all, 

	 

	I have two sipura box behind NAT.  both use via header and can
dial out and received calls without proxy.  but they have no voice when
they call to each other, any idea?
