I am trying to get a remote user working with an ATA 186 through a sonicwall VPN. I have the ATA configured to connect to the Call Manager and can make internal calls. I cannot hear or send voice when I make or receive external calls. I have tried to get my vendor to fix this, but they have been unable to complete this task. Hopefully someone here can steer me in the right direction.
I have created a page that details my layout and included the programming of my PRI router and an XL3500 that connects the Call Manager, Unity, PRI and internet connection together.
The VPN is sonicwall. I have had this working in the past, but we recently migrated to our own Unity and Call Manager from using a shared system. Now all I get is internal sound.
The page is http://www.axicoms.com/tech/pdsvoip.htm
Thank you in advance for any assistance,
