[Asterisk-biz] Asterisk integration with 2N EasyGateAnalogGSM Gateway

[Mark Armstrong]

If you limit the UDP port start and end range making it 8000 to 8040, you
should have no issue with one way audio. I will get the firmware version and
post tomorrow. It's a hexadecimal thing with certain ports having the one
way audio issue. Does not kick in until 15x approx.  This is what we have
found in Australia.

If limiting the UDP port range was the problem that would seem to indicate a
firewall setting not passing traffic it should have.  Or did the firmware
upgrade do other things that were also responsible for fixing this problem?
