You’re kidding right? I’m not sure what your question has to-do with the IP 2050 Softphone? Have you tried look at Nortel’s website?

I’ll try to answer your question but let me implore you to visit the discussion forums. I’m generally the only person that trolls the comments on my blog so I’m going to be the only person that responds to you. On the discussion forums there are multiple folks that are interested in the conversation and will generally respond in the discussion giving you a lot more help.

Is the Juniper VPN appliance in-line with your Cisco firewall? Does the Juniper VPN traffic physically traverse your Cisco firewall or does the Juniper VPN appliance have a public and private interface?

Unless you are restricting the traffic that users can pass on the Juniper VPN tunnel I don’t believe the firewall will have anything to-do with it. And from my understanding if you are running the Juniper VPN – Network Connect client in SSL mode you should be able to to establish multiple VPN connections from behind a single IP address. Each VPN connection should get it’s own private/internal IP address, correct?

The IP 2050 Softphone will open quite a few ports, I would suggest you remove any firewall rules (or run them wide open while you test).

I can test this out myself tomorrow but I would suspect that this should work fine, it may be an issue with how you have your network architected and where you have your firewall and VPN appliances.

Cheers!

In my enterprise, we recently deployed a IP softphones 2050 solution and everything is working well :
In their home, the users connect to a Juniper VPN, and they launch the IP softphone 2050 (3.03.10 version) and everything’s ok (incoming and outgoing calls).
Unfortunately we have discovered that a IP softphone can’t call another IP Softphone if both are using the same internet connection :
the line is busy, like if the other sofphone was calling someone.
The problem doesn’t occur if both softphones are using our LAN, or if the users are not using the same internet connection (and public IP)
So we think that the problem is coming from our CISCO firewall which is maybe blocking the call because the incoming and outgoing IP are the same.

Have you any idea of the reason of this problem ?
Do you know the port used by the softphone ?
We checked the firewall rules and everything looks ok

Thx again for your help !
Cheers

You might want to post your question in the discussion forums.

I’m going to guess that your VPN tunnel might be disconnecting. If you start a constant ping to the Call Server does the the ping timeout at any time? Do you have any issues with the 2050 when you are running a constant ping?

It all depends on how you’ve configured your VPN infrastructure. Some will disconnect the tunnel after a certain amount of idle time. Different routers/switches/firewalls define which traffic will reset the idle timer differently. Sometimes only Tx traffic will reset the idle timer, sometimes both Tx and Rx traffic will reset the idle timer.

Good Luck!

Any suggestion of why it would be logging me out?

In my experience unless the softphone goes completely belly up, it’s the Internet broadband connection or VPN/SSL solution that’s usually at fault.

With that said there could have been an issue with the VGMC (Voice Gateway Media Card) that was serving up the RTP stream to your softphone at the time of the problem. The logs on the Signaling Server and VGMC cards should reveal any issues.

The new release of the 2050 softphone maintains a log of events which you should be able to find here (Windows XP);
C:\Documents and Settings\UserName\Application Data\Nortel\IP Softphone 2050\Logs

Good Luck!

I’ve been using the Softphone over the VPN and a few times I’ve noticed strange sytuation. While being in call the other person would tell me that my voice is cut and they could not hear me and I could experience the same issue form my side as well. Then it would come back again and everything would be fine. It’ll be happening more then once while being connected. At one point I’ve completely lost connection with CS1000 and it recovered itself in a few seconds again.
Have you experience any of these symptoms with softphone?

Great and many thanks for tips!!
I haven’t bought any Bluetooth devices yet, but will get one in the near future and see what it will do for me.

Cheers!
