I've been pulling out my hair all day on this one. If anyone can help,
I'd really appreciate it. :-(
I've got an Aastra 9133i (with the latest firmware version) and a Cisco
7960 sitting behind a NAT device on my LAN. The Asterisk server is
hosted offsite and has a public IP address.
I've set up port-forwarding on the firewall for both phones to tunnel
the SIP messages initiated by the Asterisk box. It works like a charm
with the Cisco phone by using the following config info:
voip_control_port: 5077
nat_enable: 1
nat_address: ""
nat_received_processing: 0
Every time the Cisco phone registers with Asterisk, it does so using
port 5077 and with the corresponding port-forwarding rule added to the
firewall, it works great. However, for the life of me, I can't get the
Aastra to do the same thing. I thought that should be able to do it by
using "sip nat port: 5078" in the Aastra config file, but no dice.
Incoming calls work for about two minutes after the phone is rebooted
and then it loses its registration.
Any suggestions?
Using your browser, type http:// plus the IP address of the 9133i and
login to the phone. Then select "Global SIP" from the menu. Go down to
the Registration Period and put 100 in it. That should fix it. If not,
try the NAT settings under the Network menu. If it still doesn't work
post your settings so everyone can look at them. BTW - I have a 9133i
working behind a NAT but * is also behind it.
