Hi there,
We recently purchases the Cisco ASA 5505 to get familiar with it, possibly buying more appliances for our branch offices. However, since the appliance is installed, our SIP telephones no longer register with our SIP service provider.
The SIP phones are all on 10.0.1.0/24 while the SIP provider is external via the outside network. I copied our configuration below. Can anybody advise how to enable SIP for all 10.0.1.0/24 hosts and ports 5060, 5160, 5260, 5360?
This matter is pretty urgent...

We solved half of the issue by enabling sip inspect as outlined in the documentation. However, in addition, we need to enable it for port 5160 (5060 is working). How can we do that?
