Security in VoIP Network

Hello All,

I heard that Cisco PIX firewall is now capable of dynamically openning/closing pin-holes in the firewall to allow dynamic rtp/rtcp port negotiation. First question, is this true? can someone point me to the information on this or other sites?

Re: Security in VoIP Network

The release notes for the 5.2 platform talks about the new sip_media timeout option for rctp at:

You might also want to take a look at the option in the command reference at:

Hope this helps!
