My Asterisk set up is as follows:
– I have 2 grandstream GXP 2000 phones connected to my router
– My small linux server (with asterisk) is connected to the router as well
I have a dynamic ip from my isp provider, but I signed up for DynDNS
When I started I could call people and talk to them. If people rang me, the phone would ring, and I could hear them speak. They could not hear me. I found out this was because of the directmedia / canreinvite setting. So I set this to:
canreinvite=no
directmedia=no
Now, people could call me and I could answer. However, due to this change I can call people, but as soon as they answer, I can’t hear them, I only hear static. When I remove the two lines I add, everything is back as it was before.
What could be the issue ? The 5060 port is forwarded to my server ,as well as the 1000 – 2000 udp rang.

Ok, some information for other people in the same situation:
– check your codecs, make sure you get no errors in the Asterisk CLI (command line interface). I got errors, but it worked, so I didn’t care. That was a mistake
– upgrade to asterisk 1.8
– set directmedia = no
– it’s upd range 10000 to 20000 (I missed a 0).
This all fixed this problem.
