Phone Proxy with ASA to the side of corporate firewall
When setting up the ASA phone proxy feature, what are the options for the remote phones when the corporate firewall is not the ASA with the phone proxy feature? Internally, the default route of the network takes all external traffic through the corporate firewall and away from the ASA. I know policy routing would be an option but is there anything else that can be done from the perspective of the ASA?
Re: Phone Proxy with ASA to the side of corporate firewall
it seems i got the answer to my question from a document in Cisco...will try these.
ASA Phone Proxy can be placed behind another firewall but the external firewall... 1. Must NOT NAT the CUCM address 2. Must open up the TCP (SSL, TLS) and UDP (SRTP, TFTP) ports 3. Must ensure that the ASA Phone Proxy has a publicly routable address
