SIP trunk between pix and ISP

Hi all,

We have to configure a sip trunk between our pix 515e (version 7.0.4) and the service provider's sip network. Does anyone have experience on this? Is their any step by step guide for pix?

Regards

Irs

Not sure what you mean, but you can't terminate or configure SIP trunk on PIX firewall.

Yes, you can pass SIP traffic through PIX firewall.

All you need to do is enable sip inspection, and also configure the necessary NAT translation and open up access-list to allow SIP traffic through.

The sample configuration that you reference has the sample configuration for SIP, just look through the "Configurations for SIP" section.
