[Serusers] Clients connected - can call, but no voice

[René Nielsen]

The Server (ser 0.9.3) is behind NAT - together with the one client,
both clients can call the other part, Part a (behind nat) - cannot hear
what part B says, but part B can hear what part A says.. Part b is
connected directly to internet, throug a Sipura 2100..

Someone with a Idea what could be wrong?

(ports open in NAT router are from 5055 - 5075 and 8100 - 65000) those
ports point to the SER server
