1. Brekeke Product Name and version:
2. Java version:
3. OS type and the version:
4. UA (phone), gateway or other hardware/software involved:
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :
6. Your problem:
I have 2 identical VoIP boards, each under the LAN of a router. Board #1 is under D-Link WBR-2310 router (Router #1). Board #2 is under Belkin F5D7230-4 (Router #2). WAN ports of both routers are under the same network as BSS. I have opened port forwarding for both routers.
The problem is that the 2 boards register differently. UA1 on Board #1 is registered with its on LAN ip and UA2 on Board #2 is registered with Router #2's WAN ip. When UA2 call UA1, UA1 has to answer within 1-2 rings, otherwise the call would be automatically cancelled. It seems ok when UA1 call UA2.
Is there any settings on the router to solve this problem?
Thanks. |

It is interesting.
Can you use wireshark and paste the packets here? |
