[Users] rtpproxy still not working for me - sr-users

28 Sep 2006

Status:
openser compiled, including mysql
openser working with mysql (registering)
openser server has two ethernet ports with one public and one private IP
rtpproxy is running without any parameter

7311 is eyebeam on local desktop
7312 is gizmo  on the same local desktop
7111 is a grandstream   remote, behind a nat

Openser adminstrator shows all three phones as registered with following 
sip addresses:
sip:7111@192.168.10.91
sip:7311@192.168.250.108:42800;rinstance=f17a00051f63a625
sip:17476063396@proxy01.sipphone.com:5060                         <=== 
that should be 7312(a)192.168.250.108

Internal calls:
call from 7312 to 7311  works.
call from 7311 to 7312 ends up at a voicemail box  (most likely gizmo 
problem)
call from 7311 to 17476063396(a)proxy01.sipphone.com   ends up at the 
voicemail box

External calls:
call from 7311 (local phone) 7111 (remote phone behind NAT) does not 
work, see the ngrep info below.
Looking at the output I feel that the nathelper is not working. As I 
understand the documents, the address should be replaced with an public 
IP address, but it uses my servers internal ethernet port (192.168.250.41)
5.32.86.166 in alt1 is the IP address of my Hamachi network. I have no 
idea, why this one shows up here.
