[Users] Openser and MediaProxy - sr-users

7 Jul 2006

Hello all:

    I suppose this is not the first time that someone make this question, you may be tired
of this, but believe me, I've not found much information about this.

    Here we go: Can you help me to make my Openser work with Mediaproxy. Below is my
openser.cfg and my mediaproxy.ini

    A call from a Nated Calling Party results on "Message to big" error.

    Thanks in advance, guys.

[Dispatcher]
;
; Section for configuring the proxy dispatcher
;
; The following options are available here:
;
; start         Boolean value that specifies if to start the dispatcher.
;               Default value: Yes
;
; socket        Path to the UNIX socket where the dispatcher receives commands
;               from SER. This should match the value for mediaproxy_socket in
;               openser.cfg. Use the keyword None to disable listening on a
;               local socket.
;               Default value: /var/run/proxydispatcher.sock
;
; listen        Network address where the dispatcher receives commands from
;               a remote Mediaproxy to close sessions for which media did
;               timeout.
;               Valid values for this are:
;
;                - Default
;                    when using this keyword it will listen on 0.0.0.0:25061
;                - address[:port]
;                    listen on the specified address and port
;                    address can be an IP a hostname or the keyword Any 
;                    (in which case it will listen on 0.0.0.0). If address is
;                    a hostname, that should map in DNS to an IP address
;                    present on the machine, through an A record.
;                    If port is missing assume 25061.
;
;               Default value: Default
;      
; group         Put the socket in this group and make it group writable.
;               Default value: openser
;
; defaultProxy  Default mediaproxy to use in case the From/To domains
;               involved in the call don't define any.
;               Valid values for this are:
;
;                - None
;                    don't use any default proxies. domains without
;                    mediaproxy SRV records won't work
;                - /path/to/unix/socket
;                    use a single MediaProxy server identified by the given
;                    UNIX socket path
;                - IP_or_hostname[:port]
;                    use a single MediaProxy server identified by its network
;                    address. The network address consists of an IP address
;                    or a hostname and an optional port number separated by
;                    a double colon. If port is missing 25060 will be assumed.
;                    Examples:
;                       10.0.0.1    (connect to 10.0.0.1 on port 25060)
;                       10.0.0.1:90 (connect to 10.0.0.1 on port 90)
;                       mp1.mydomain.com
;                       mp1.mydomain.com:7000
;                - domain://domain_name
;                    Use all MediaProxies defined by domain_name, honoring
;                    their priority and weight to create a cluster of proxies
;                    with fallback and load balancing capabilities.
;
;               Default value: /var/run/mediaproxy.sock
;                       
start = yes
socket = /var/run/proxydispatcher.sock

[MediaProxy]
;
; Section for configuring the MediaProxy server
;
; The following options are available here:
;
; start         Boolean value that specifies if to start the RTP proxy server.
;               Default value: Yes
;
; socket        Path to the UNIX socket where MediaProxy receives commands
;               from the dispatcher or SER. Use the keyword None to disable
;               listening on a local socket.
;               Default value: /var/run/mediaproxy.sock
;
; group         Put the socket in this group and make it group writable.
;               Default value: openser
;
; listen        Network address where MediaProxy receives commands from
;               a remote dispatcher.
;               Valid values for this are:
;
;                - None
;                    don't listen for network connections at all
;                - address[:port]
;                    listen on the specified address and port
;                    address can be an IP a hostname or the keyword Any 
;                    (in which case it will listen on 0.0.0.0). If address is
;                    a hostname, that should map in DNS to an IP address
;                    present on the machine, through an A record.
;                    If port is missing assume 25060.
;
;               Default value: None
;      
; allow         List of addresses that are allowed to connect to this
;               MediaProxy server and send commands.
;               They are specified as a comma separated list of entries, with
;               each entry being specified in the CIDR network/mask notation
;               (ex. 10.0.0.0/8)
;               
;               In addition simple IP addresses or hostnames are allowed, in
;               which case the mask is considered to be 32.
;
;               In addition to network ranges/addresses 2 keywords can be used
;               for this option:
;                  None   to specify that none is allowed to connect (not very
;                         useful but this is the default for security reasons)
;                  Any    to specify that anyone is allowed to connect
;                         (dangerous!)
;
;               Example: allow = 10.0.0.0/24, home-pc.mydomain.com, 1.2.3.4
;
;               Default value: None
;               
; proxyIP       IP address to use to talk to the phones. If not specified, the
;               first found will be used. However first found usually means
;               first defined in /etc/hosts which may not be what you want.
;               If you find that the address that's automatically selected is
;               not the one you want, you can specify the right one using this
;               option. The address must be one that's present on one of the
;               host's interfaces.
;
; portRange     The range of ports to use for proxying the rtp streams.
;               This option is specified as minport:maxport with minport and
;               maxport being even numbers in the range 1024-65536
;               Default value: 60000:65000
;
; TOS           Mark all forwarded RTP packets with this specific TOS value.
;               Unless you know what TOS means, leave this option alone.
;               The TOS value can be specified either as a decimal number or
;               as a hex number in the 0xnn format.
;               Default value: 0xb8
;
; idleTimeout   Expire idle sessions after this much time.
;               Default 60 seconds
;
; holdTimeout   Expire calls on hold after this much time.
;               Default value is 3600 seconds
;
; forceClose    Forcibly close a RTP session after this many seconds even if
;               it's still active. If forceClose is 0, then a session is never
;               closed no matter how long it lasts.
;               Default value: 0
