Hi Asterisk users
I have a problem with a configuration as shown in the diagram
+-----------------+
| PBX/STUN server |
+-----------------+
|
|
|
+-----------------+
| FIREWALL & NAT |
+-----------------+
|
|
|
+-----------------+
| PUBLIC INTERNET |
+-----------------+
|
|
|
+-----------------+
| FIREWALL & NAT |
+-----------------+
|
|
|
+-----------------+
| SIP CLIENT |
+-----------------+
Chanel configuration as follows in sip.conf
[2103]
type=friend
context=limited
username=2103
secret=XXXXXXXXXX
callerid="Hayetaipaq" <2103>
calleridnum=2103
host=dynamic
nat=yes
disallow=all
allow=gsm
allow=ulaw
allow=alaw
mailbox=2103
It happens to work quite well while the client connects directly to a public
Ip addressing schema, but when the client is behind a second NAT I only have
one way voice either outgoing or incoming but never both at the same time.
Does an STUN server will solve the problem ??? Is it possible to use a third
party STUN server outside the PBX network?
Thanks in advance asterisk users!
