I will be testing using an IP Phone 7960 and softphone from a home office to corporate through a pix 501, over DSL, to VPN 3015 Concentrator 3015.

Any hints or heads-up that anyone can provide would be helpful. What are the issues, tricks, etc.?

Thanks

Well you might want to look over the following doc if you need to tune the 7960. http://www.cisco.com/warp/public/788/AVVID/tuning_voice_for_ip_phone.html and this link is very helpful as well http://www.cisco.com/warp/public/788/AVVID/ccmaaut.shtml

There is a bug with the PIX and zero-byte TCP keepalives (CCM happens to use them). Workaround is to downgrade the PIX to 6.1.3 or upgrade to 6.1.5 when it is released (fixes will also be in 6.2.3 and 6.0.5)
