ASA 5525X and SIP

                  Guys,

A nice simple one for the firewall Gurus out there:

I'm thinking of replacing a tired old Checkpoint firewall cluster with  Cisco ASA 5525Xs. I have read the manuals and it looks like this model is SIP aware, but I'd like to hear of anyone's experiences. I have a simple requirement, I'm on a network with Cisco switches/routers, and NEC C3 telephony and I would like to run SIP phones outside the firewall, so SIP awareness is important.

Any comments would be very welcome

Thanks

Jim

ASA 5525X and SIP

Hello Jim,

Cisco ASA Firewalls come with an Embedded SIP inspection that will allow you to capture the signaling flow of a SIP session so then the RTP data flow can be dynamically opened while at the same time making sure the data enforce what the RFC states for the SIP protocol.
