[asterisk-users] Linksys not Ringing

No... you can (and probably should) Dial() an extension before
answering the incoming call.

Do a sip debug and see if the Sipura is getting the INVITE message
(and responding with an ACK), and if it sends back a RINGING message.
Something strange is going here, and my bet is on some kind of NAT
screw-up.
