Hi
there!
I installed the
BudgetTone (GrandStream) on my LAN without any problems. Then, I moved it
to another location using a D-Link NAT.
I opened 5060 (SIP)
and 5000 to 5008 for RTP. I also fixed the IP address of the
BudgetTone.
When I receive a
call on my Asterisk, it would ring my FXS as before. However, after I pick
up, it hangs within a few seconds (Hungup Zap1-1 in the
log).
The configuration
I have in * is the following:
sip.conf
-----------
[general]
port=5060
context=sip
maxexpirey=3600
defaultexpirey=60
disallow=all
allow=ulaw
allow=gsm
[1000]
contet=sip
type=friend
username=1000
secret=?????
(not the real one)
host=dynamic
mailbox=1000
canreinvite=yes
dtmfmode=rfc2833
I did not change the
above configuration when I moved the budgetTone from the LAN to the Internet
(Wan).
I am not using a
"register" statement in the sip.conf and I am wondering if I need
to.
I did change the sip
server IP address in the Grandstream configuration.
I suspect my problem
is with the router (NAT). I don't quite understand the symetric
discussions but I downloaded a paper to learn more. Right now, all my
public and private ports are the same.
Regards,
Uriel
