i2050 Softphone can't transmit to BCM 50 thru LinkSys W54AG Router

[BillW844]

My Nortel i2050 softphone can not transmit to the BCM 50 Rls 1 from outside my network through a LinSys W54AG router. Everything else works great, I can get dial tone select lines make calls and I can hear the called party. People can even call me and I can hear them they just can't hear me. When connected on on the LAN side to the BCM 50 it works perfectly.

I believe I have all of the necessary ports open on the LinkSys.

Can anyone help Please!

Consumer grade wireless is not necessarily capable of handling VoIP. It may work sometimes and sometimes not due to the half-duplex nature of wireless.

You shouldn't need to open any ports on your linksys and both your host pc and bcm should be on the same side of the firewall.

It sounds like you have a gateway issue. You can reach your lan, hear their packets, but none of your packets are getting outside your lan.

Thanks for the reply! When I connect remotely accross the internet into the BCM on the LAN everything works except people can not hear me...I can hear them just fine and the i2050 looks fine it has the proper displays, dial tone works. They just can't hear me when I call in from outside the LAN. Also I am not using the wireless part of the router.

You have a routing issue. I am assuming that you are doing port forwarding through the Linksys and not VPN?

 

[BillW844]

I have not done port forwarding and don't know what ports to forward. I will get a VPN router soon but I would really like to make this work if possible even if the service is poor.

So, if I'm understanding you correctly:

BCM behind your router (DMZ?) and i2050 on the greater public internet.

You need to Port Forward ports 7000, 28000-28500, 51000-51285 (I think that's the range, but someone will correct me if I'm wrong) from the WAN to your BCM's IP address. You will need other ports too if you want to manage the BCM from outside (these ports are even farther from the front of my brain).

This setup will work sometimes, but the service will be sporadic and you've exposed your BCM to the greater internet for hacking.

Caveat emptor.

Is the problem that you are connecting back into the main location (where the BCM is) via a VPN tunnel using the Linksys Router. Is your connection to the Linksys via the wireless.

I have seen that problem when connecting to a CS1000 with the I2050 using the wireless connectin to the router. If I use a wired connection then I don't have a problem.

 

[BillW844]

The problem is transmitting back into the main location (where the BCM is located) I am not using wireless it is a cable connection from the LinkSys router to the BCM.

Any thoughts would be appreciated.

The voice packets are obvioulsy not making across the internet to you or are being blocked at the i2050 end by another router.

What is the network makeup at the remote site?
