Hi,

i have a cisco 7204vxr router (c7200-is-mz.123-6f.bin)and on one of the networks (wich is a nat) there are sip clients connected to a sip server on another network. What is happening is that the router is acting as a ALG/SBC changing the sip/spd information inside the packets.Since i have another equipment doing SBC function, i would like to know how to disble it on the 7204vxr.I have searched a lot, but could not find and answer.

Thanks for your help,

AndrÃ© Santos
