UC500.com

Hi,

I hope you can help as this has had my head in knots.

We currently have a UC520 in our office with a number of phones. This site is all working correct until it comes to calling our remote office or vica-versa through DDI. I have been told we are able to do it but have been unable to find a solution.

What I have a is a sonicwall at each site and two different address ranges.

Office 192.168.10.x
remote 192.168.11.x

The sonicwall is being used to create the VPN as we had issues creating the VPN between the UC520 and Sonicwall. The phones in the remote office are able to get there DDI's and call there voicemail and ring out. The problem is when they try to call the office on there DDI or the office tries to call the remote site. The phones ring but when you answer at either end, the line is active but nothing can be heard. If you call for long enough you get put through to there voicemail with no issues.

I appreciate any help you can give.

Cheers

Rob
