I don't have a lot of experience with mediaproxy, and I have some doubts that such you
see they can help me to clarify, inside the file mediaproxy.ini some options appear which
I have configured them but I am not sure if it is the best way.
my scenario is the following one:
<-> UAC<-> NAT <-> ADSL <-> Internet <->
eth0 wan (public ip x.x.x.x ) <- openser/mediaproxy/asterisk -> eth1 lan
(192.168.11.1) <-> UAC
[MediaProxy]
start = yes
socket = /var/run/mediaproxy.sock
group = openser
listen = None
allow = None
proxyIP = x.x.x.x (public ip)
;portRange = 60000:65000
portRange = 35000:65000
TOS = 0xb8
idleTimeout = 60
holdTimeout = 3600
forceClose = 0
[Accounting]
; one of none, radius or database
accounting = none
[Database]
user = dbuser
password = dbpass
host = dbhost
database = radius
table = radacct
[Radius]
secret = secret
server = localhost
authport = 1812
acctport = 1813
dictionaries = /etc/radiusclient-ng/dictionary, /etc/openser/radius/dictionary,
/usr/share/mediaproxy/dictionary
retries = 2
timeout = 3
this couple of you line inside the openser, I don't still understand them according to
the guide of ser getting started they are for asymmetric clients, but I don't find an
example
modparam("mediaproxy","sip_asymmetrics","/etc/openser/sip-clients")
modparam("mediaproxy","rtp_asymmetrics","/ect/openser/rtp-clients")
somebody that can give me a good help...
regards
