Asterisk / Network expert needed
Budget: £20 – £250 GBP
We have a problem with a Cisco ATA-192 that will not register with our Asterisk server. With tcpdump we can see REGISTER attempts from the ATA and a 401 response being sent back, but nothing further. We suspect it may be a NAT issue. The remote end is behind a broadband router and is NAT'd. We need a network expert that also understands Asterisk and SIP. Also, ideally how to configure a Cisco ATA-192.
