Hi everybody! In near future our company is going to subscribe to SIP services, but i'm not sure how it will work through ASA firewall. I heard that NAT causes problems for sip telephony. What kind of minimum configurations should i make on ASA to allow sip to function properly?
Thanks! We are using avaya for telephony. We don't have a router running CUBE, so i guess directly to PBX. But i heard that inspection should be enabled, so it can translate the private address of sip to public(to avoid one way audio problem)? Could you you explain
I would check that your Avaya can support the required SIP parameters for the provider. Certainly in my experience every SIP provider seems to do things slightly differently!
With regard to the inspection I guess you can try and see. It's just a check box for on/off on the ASA and you'll soon find out if it works or not! Again in my experience it needs to be turned off! I have recently worked on a few installs of Mitel systems using SIP behind ASA and the SIP inspect caused one way audio!

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
