Since the VPNremote phones are remotely connecting it is a good idea to place the
VPNremote Phone extensions on their own IP Network Region. Due to a wide range of
home network ISP bandwidths, a codec setting of G.729 with 3 Frames per Packet is
suggested. This allows for a larger range of users to use the service.

12 Frequently Asked Question
12.1 How do I know if VPNremote phone will work with my security gateway?
Refer to “Preparing Security Gateway for Remote Access” to see what are the various
methods supported by VPNremote Phone for building IPsec tunnels. The table below
shows which security gateway has been tested with VPNremote phone. If your security
gateway is not in the list below Refer to your security gateway manufacturer provided
admin guide to see if security gateway supports Xauth with preshared key. If answer is
yes try using one of the predefined 46vpnsetting.txt templates. If none of the predefined
templates work contact Avaya Support, some tweaking of the templates might be
required to get the VPNremote phone work with your security gateway. Most common
reasons are
• Proprietary Xauth extension (For example Nortel).
• Security Gateway expects IPsec clients to use something other than “ID_KEYID”
and “ID_USER_FQDN” as IKE ID type.
• Security Gateway cannot handle multiple IKE proposals sent by IPsec clients.
• Security Gateway enforces strict match for IKE and IPsec SA life time.
