<DIV><SPAN class=663400501-18012005><FONT face=Arial color=#0000ff size=2>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).</FONT></SPAN></DIV>
