How do I configure the Cisco ATA 190 for SIP?
I am unable to send or receive calls using my landline that is attached to the ATA and then the router. This is due to the fact my VDSL modem does not have an RJ45 port which has caused me to purchase an ATA. I attach the phone to the ATA and then the ATA to my WiFi router's Ethernet port, then the WiFi router into my VDSL modem.
The modem does not have an RJ45 port.
Sorry, it's a Cisco 191 ATA.

you should check the manual. Cisco firewalls are notoriously complex to setup. it would take more than a paragraph to tell you how...
