Hello All, I'm setting up 20 IPSec VPN's using RVL200's to my Cisco PIX running OS 6.3(4). I'm able to connect to the PIX with my RVL200 and ping all device through the VPN. The problem I'm experiencing is with my Nortel VoIP phones they connect to the Phone server and give me the proper indication that the phone is working however if I pickup the hand set i get no dial tone. I connected another IPSec firewall that i know works with the PIX and the phone works great. Is there any know issues with the RVL200 and UDP traffic over the VPN? does the new firmware address this? thanks for the Help!!
