Sonicwall and direct media path issue on remote sites

[trinetintl]

We have a customer that has two remote sites all linked together with SonicWall routers. The two remote sites have IP telephones and I cannot get a direct media path connection between the IP phone on the remote sites. Phones ring OK, they connect OK but no voice. I am having the IT guy turn on the "Enable H.323 Transformations" on all the routers as per the Avaya application notes for configuring a SonicWALL VPN solution....I am still waiting for him to enable this feature and to see if it works.

Some additional details:
- Direct Media Path is enabled on all the H.323 extension in the IP Office.
- Obviously I can make a connection between IP telephones located in the same remote site confirming that direct media path is working OK.
- IPO is a V1 on 8.1.65

Am I missing anything? Can anybody think of anything else that I can I tell the IT guy to do to make this work?

Thanks,

Quick follow up; activating "Enable H.323 Transformations" did not work.

Bas1234 You may be right...I asked the IT guy if he could ping a PC from between remote sites and his answer was no. He is trying to create a VPN tunnel between the remote sites, I asked him to simply setup the proper routing. What am I going to have to do if he create a new VPN tunnel between the remote sites bypassing the main site?

He just needs to get his routing right, also might need to check the switch if you have VLAN Routing enabled if you have a data and voice vlan

I do have another media path issue not sure if I should create another thread, please let me know guys.

This new media path issue is between a remote site serviced by IP telephones that has a tunnel to the main site using Juniper routers and a remote site with a 9620 that is setup as a VPN telephone tunneling to the Juniper on the main site. I know the problem is that the remote site IP telephones cannot see the VPN telephone. I am trying to figure out what is the best and most efficient solution to solve the problem; (a) Install a Juniper at the remote site and turn the VPN phone to an IP Phone or (b) figure out a way via routing to enable the remote IP telephones to see the 9620 VPN telephone but if we go this route then which one is the important IP address to establish a media path the one issued by Juniper for the VPN tunnel or the one issued by the DHCP’s LAN?

uncheck allow direct media path until your data guy fixes the vpn tunnel, you should now have two way audio, but will, use a vcm for each call this way so make sure you have enough vcm's if you do this! this is only a temp fix

smokingjoe....I was reading my last post and I focused on the new issue and not on updating the old one. The IT guy added the appropriate routing and everything started to work. Now my issue is with this other client that has the 9620 VPN phone and the remote site. For this second project the site should have enough VCM's to leave it permenent...let me try to connect to the IPO to see if the media path is still on.

The VPN phone's extension should not have DMP enabled.
Is this the case? then turn it off and try again.


BAZINGA!

I'm not insane, my mother had me tested!

 

[trinetintl]

tlpeter...where is the DMP option? I can't find it under the H323 extension, VoIP tab.

DMP is direct media path. It's on the VOIP tab of the extension.
