I have a cisco switch in a remote site that users are connected to and thats connected to the local cisco firewall, that has a vpn site to site connection to corporate.
In corporate I have installed IP phones and everything is going fine. However, I installed a IP phone in the remote site and it connected to the voice system and downloaded its updated firmware etc but when dialed it rings but no voice and when they call corp my phone rings but no voice.
I noticed that on the IP phone in the remote site it's not getting an IP address from the Voice VLAN that I set up in corp. I figure I need to configure the switch in the remote site with the approriate vlans so it can communicate but how? Data between the 2 sites transfers fine.
