| We have got SIP clients connecting to our Asterisk fine with a DSL

| ATA to a Rogers Cable connection behind a Netgear router (NAT), the
| SIP clients aren't able to reach the Asterisk at all.
|
| We enabled the SIP debug in Asterisk, and it doesn't see any
| request coming from these SIP clients, and we also tried the to use
| a XTEN Lite to connect to Simpletelecom within this network and it
| fails to register as well.
|
| It seems to be a network configuration problem, but there isn't
| much log in the router that we can dignose as the Netgear router
| WR814 only logs TCP web requests.
|
| Does anyone know what the problem could be?  Does Rogers Cable
| blocks SIP ports? _______________________________________________
