Hi,
I am using the example "gw-pstn" from Getting started. I followed
the guide to setup mediaproxy for handle NAT function. However, I
can't make call between Internal IPphone to PSTN. Anyone can help me
to analyze why it doesn't work.
After using mediaproxy, I found that some data are stored in the table
"Location" compared not using mediaproxy. The field "contact"
contains "sip:number@internalIP:port" and the field "received"
contains "sip:externalIP:port". Is it correct after using mediaproxy?
I have a look for the log from ngrep and some extra parameters "rport
and receieved" in the header.
When I try to make a call from internal IP phone to PSTN, the error
"500 FQDN in SDP Media cannot be resolved.". I think it is still a
NAT problem and it seems to use the internal IP instead of external
IP. As the same time, Cisco shows (no route to destination (3)).
When I try to make a call from PSTN to internal IP phone, the error "
Too Many Hops", which is the error message in the openser.cfg file,
shown. I do think it is the same reason as the above case.
Below are the log from ngrep during making a call. openser.cfg and
mediaproxy.ini are also listed below. Please help to figure it out
the problem. Many thanks!

; Configuration file for MediaProxy
;
[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 ser.cfg
; Default value: /var/run/proxydispatcher.sock
;
; group Put the socket in this group and make it group writable.
; Default value: ser
;
; 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
;group = ser
;defaultProxy = /var/run/mediaproxy.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.
; Default value: /var/run/mediaproxy.sock
;
; group Put the socket in this group and make it group writable.
; Default value: ser
;
; 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: 35000:65000
;
; TOS 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
;
