[Asterisk-Users] Registering Remote Sipura to Asterisk (both behind firewall)

[Lucas Alvarez]

Hi, you have to forward port 5060 udp and all  the others udp ports that 
asterisk uses for RTP, 10000 to 20000 by default, see rtp.conf.
At the sipura device in the server configuration you have to put the LAN 
ip of your Asterisk box as sip proxy server and firewall's ip as 
out-bound sip proxy.
