video call not going from polycom's end terminal(Lifesize team 220)!

video call not going from polycom's end terminal(Lifesize team 220)!

We are using polycom video conferencing solution with RMX 2000 as
multiparty confrlerencing unit, DMA 4000 as gatekeeper to register devices
and also act as SIP proxy. RPAD acts for firewall traversal. Except RPAD
all other servers are kept in MZ. Rpad is in DMZ. The end terminal used is
of Lifesize Team 220. Now the situation is I am able to make call(using
H.323) from internet to the end terminal but not the reverse, that is from
end terminal to devices kept in internet. As per the network guy the
packets have not been initiated at all from the end terminal. So probably
its some configuration issue of the rpad or dma or rmx. Need some help in
this. What could be the possible issue/solution?
