ASA as a SIP ALG?

Guys,

 

Struggling with ASA and SIP.

 

SIP inspection is enabled, and I have some NATs configured for a public Internet SIP service.

 

Inbound/outbound calls connect, but we are having 1-way audio (private to public ok, public to private nok)

 

This is because the SIP INVITE SDP header is using the private IP address of the handset, and the ASA is not rewriting it to the required outside public IP address.

 

What am I missing to get the ALG part of SIP inspection working?

 Hey, You ain't missing

 

Hey,

 

You ain't missing something, that's the whole purpose of the SIP inspection ALG, make sure that value inside the SIP payload get's translated properly.

 

If that is not taking place then you got to be hitting a bug.
