For a pretty long time I had been using Sorensen VP 100 and VP 200 which required Dlink wireless router (DI-524). Until I had received another videophone device, Ojo 900 I had figured out how to resolve router issue in reference with the print server.
Dlink router is fine but does not send enough signals via wireless to one of our desktop computers upstairs. Even there are four ports limited and insufficient for several computers and all in one printer. In anticipation of better wireless reception, I had brought in a new wireless router called Belkin N Wireless router with current Dlink router but had to hook up cables to these routers and print server.
First, I had hooked up four ports on Belkin router to my primary computer, cable modem, print server and SVP 200. Next, the print server was connected to Dlink router, all in one printer and Belkin router. Lastly Dlink router was connected to Ojo 900. Doesn’t it look like complex of cables and devices? There are very ugly cables hidden behind my office desk as hanging in air like vines growing on the wall.
One problem is that how to configure port forward and base IP address. Of course, we normally type 192.168.2.1 on the Internet and look for virtual servers to set up the router configuration.
Strangely, Ojo 900 worked beautifully and had auto self configuration in the beginning. SVP200 did not appear right and however, I could see myself on the screen but not another caller’s screen. The screen was black.
Frustrated, I had searched Sorenson VRS web page for technical support about configuration issue but to no success. I had called Sorenson VRS Technical Support on Ojo 900 via video relay service but relay agent stated that the phone number was VP. I was puzzled why Sorenson VRS Technical Support had advertised the phone number on its website but instead, I had sent an email.
Finally I had received configuration for SVP200. To type (description) vp1 and (inbound port) 1720, (type) TCP, and (private port) 1720, and in next line; (description) vp2, (inbound port) 15328-15348, (type) TCP&UDP and (private port) 15328. I was able to detect IP address by looking up at DHCP Client List.
After I had configured SVP 200 with the Belkin router, SVP 200 works fine. On the other hand, Ojo 900 did not work right because I could not see another caller’s screen as it was black.
As I had checked through SNAP! VRS that had provided Ojo 900 for technical support I couldn’t find information but had found several resources. One resource that I believe is very good informative and is called Ojo Labs or Ojo Phone. Second one that covers all types of routers is called Port Forward.
Once I had configured virtual server for Ojo 900 by typing (description) ojo1, (inbound port) 5010 – 5017, (type) UDP, and (private port) 5010-5017, then I typed in next line: (description) ojo2, (inbound port) 5029, (type) UDP and (private port) 5060. Lastly I had pressed bandwidth profile key to “Custom” on Ojo Connection Screen. At last, Ojo works fine.
Sometimes it is confusing and complicated if someone doesn’t know much about networking. However, I hope this information may be of useful for your reference in case.
On the bottom line, the combination of both two videophones and two routers may work well but sometimes had caused snags lately. In order to make all routers and VPs working, one way is to unplug the Belkin router, wait for 30 seconds and plug it. Sometimes I find another caller’s screen still black on Ojo 900 and check the connection screen to be sure the bandwidth profile should be custom.
It is a challenge with multiple videophones and routers but in next step I will look forward to another challenge with ten digit numbering.
