on
We have a NEC 8100 phone system.  At the main site where the system is we are using a TZ200 at remote site we have a TZ100 with a site to site VPN.  The phone rings on the other side but there is no voice between sites.  I have opened VOIP ports, plus ports 10000 - 20000 and ports 5080-5081.  Sip transfermation is disable on both.  Can anyone help me?????

Hello,

I have had this problem before.

Your Telephone System should have three IP Addresses.  Signal, Voice 1 and Voice 2.

Ports 5080 & 5081 must be forwarded to the IP address in command 10-12-09.
Ports 10020 – 10051 must be forwarded to the first IP address in command 84-26.
Ports 10052 – 10083 must be assigned to the second IP address in command 84-26.

Enable QoS for the Voice Traffic as well.

1.  Internal IP's or External IP's?
2.  Do I open up ports on both devices or the device where the phone system is?
3.  Would the first ip address in command be my nec system ip address?

1. The Internal IP's of the Telephone System.
2. Just at the System End I believe.
3. The first IP address would be the NEC System Address.
4. Make sure the SonicWalls aren't blocking anything on those ports.

Presuming you have static IP's on the Terminals?

Do you have tech support with NEC?

My partner has support with NEC but he is out of town.  I may have to him give me is info for support so I can call them.

Does NEC know about this issue?

Do you know where in the NEC configuration I need to add IP's?

No problem :)

NEC will be able to talk you through a few things.  The last VPN I did with two SV's was with Drayteks and it was doing something simular to this.  Turns out that the Draytek 2830's have a bug in them preventing it :S.  Replaced them with 2820's and it worked perfectly.

Another thing to check is that you can telnet those ports on the Telephone System from the remote location.

I tried the the forwarding method you advised but that didn't work....  I forwarded the ports to the ip addresses in the phone system.

How did your call go with NEC?  Did you manage to resolve it?

Author

Commented:
They had to reschedule the call, but as soon as I know the fix will will definitly let you know.  I know that others are having similiar issues.

I also have an issue with an IP phone that will connect to one site but won't connect to another and all routers are setup the same.
