I have something similar like below.

My asterisk box has 2 ip (public and private).
If i call to ekiga (locate as the same private ip), i can see incoming video at my handphone.

And for other scenario, i have to call to public ipphone. The result was cannot see any video at my handphone.

I have enabled nat option at asterisk.
From tcpdump, i found out that i received stream from public ipphone at my public ip. And sip messages at private ip.


Is there solution to fix my problem?

Thanks

It should work without videocaps branch.

Why don't you test:

3Gphone --Zap--> [asterisk1] --> Sip Phone

yes : in sip.conf, you may use two parameters : externip and localnet.

The first should be used to describe the private network that you are connected to and the second should be used to specify you public IP address.

public IP address.

Isn't it other way around? externip should be my public ip, and localnet is my subnet?

externip=mypublicip
localnet=172.x.x.0/255.x.x.0 ;subnet

I tried your method;
Sip exchange happened at my private ip, the connection ip at SDP was set to my private ip.

But no rtp stream received at my public ip.

I tried this to:
externip=mypublicip
localnet=172.x.x.6/255.x.x.0 ;real privateip

I received rtp stream at my public ip, but still cannot see anything at my handphone

Thanks

in the section describing public ipphone add
canreinvite=false

Thanks
