Hello all,
Please read through before commenting on this.
My client has had a VSX 7000 unit and it has been working for video conferencing fine for the past three years.
Suddenly this past week we can call out but when the remote side answers the call they can see us and hear us, but we cannot see them nor hear them. We get a black screen with a open padlock in the bottom right corner.
I have the following ports open for it, and yet I know it is overkill but we have been trying everything we can think of:
1720 - TCP
3603 - TCP
389 - TCP
3230-3253 - TCP
3601 - TCP
1731 - TCP
5060 - TCP
1720 - UDP
1718-1719 - UDP
3230-3341 - UDP
5060 - UDP
49236 - UDP
These are bidirectional.
These have been open up and the same for the last three years.
I called Polycom tech support and they stated that this is due to the ports not being open.
What? It has been working for three years with NO problems and now it doesn't work and suddenly the ports are at fault?
Has anyone seen this where the DSL router that you have has to be replaced?
Or could this be an issue with the Polycom unit itself?
Thanks,
Kelly W.
Hi there :)
is nat enabled and configured in the firewall settings if your vsx ?
Is the "Fixed Ports" option ticked on the same page ?
Hello,
Yes it is.
At least I believe it was since it had been working for three years with no problems.
Where on the VSX would I go to check it?
Thanks,
Kelly W.
System > Admin Settings > Network> IP> Firewall
Select fixed ports and select NAT:Auto
The system should take a public IP from Router or ADSL modem.
If NOT, set this option to manual and enter your public IP in the corresponding field.
Double-check that your have a correct portforwarding configured on your router/firewall to the lan ip of the vsx.
Do a test call to: 71.14.2.158 (Gary´s test site with a hdx system)
By the way: Is it possible, that the vsx IP adress has changed ? That would mean, that the port forwarding is incorrect and therefore the incoming packets are routed to the wrong ip adress.
Hello,
No the internal IP address has not changed, I made sure of that as a first step.
Also the external IP address has not changed. They have a static IP address.
Thanks,
Kelly W.
Have you already checked the other settings i´ve mentioned ??
Hello,
Not yet. Forgot the password to remotely get on to the unit (through a PC and logmein.com).
Not on site like I was earlier.
One of the users is going to email me the password in the next short while.
Thanks,
Kelly W.
Hello,
Okay everything is setup as you stated.
When I try to dial out to the IP address that you gave me it came back (this is from the web browser area) and states:
The far end system is capable of accepting your call, but the call was rejected for an unknown reason.
Thanks,
Kelly W.
Could you try to dial: 71.14.2.157 (which is also one of gary´s test machines) or one of the polycom test sites from the directory ?
Hello,
Okay I will have to do the calling when I am on site.
I will be there on Monday morning to do this.
Thanks,
Kelly W.
