Dear sir:
I am using a Cisco 3660 router as a SIP-PSTN gateway with my SER server.When I have configure all the thing has the guideline,I meet a problem.If I use a telephone call my MSN Messager or use MSN Messager call the telephone,the receiver could ring,and the MSN Messager could send and receive signal,but the telephone could only receive.In other words,the RTP packages could not send to UA at computers from the router.Does anyone can help me?
This is the configure at SER server:
# ------------------ module loading ----------------------------------
loadmodule "modules/sl/sl.so"
loadmodule "modules/tm/tm.so"
loadmodule "modules/acc/acc.so"
loadmodule "modules/rr/rr.so"
loadmodule "modules/maxfwd/maxfwd.so"
loadmodule "modules/mysql/mysql.so"
loadmodule "modules/auth/auth.so"
loadmodule "modules/auth_db/auth_db.so"
loadmodule "modules/group/group.so"
loadmodule "modules/uri/uri.so"
# ----------------- setting module-specific parameters ---------------
modparam("auth_db", "db_url","sql://ser:heslo@localhost/ser")
modparam("auth_db", "calculate_ha1", yes)
modparam("auth_db", "password_column", "password")
# -- acc params --
modparam("acc", "log_level", 1)
# that is the flag for which we will account -- don't forget to
# set the same one :-)
modparam("acc", "log_flag", 1 )
# ------------------------- request routing logic -------------------
# main routing logic
route{
/* ********* ROUTINE CHECKS ********************************** */
# filter too old messages
if (!mf_process_maxfwd_header("10")) {
log("LOG: Too many hops\n");
sl_send_reply("483","Too Many Hops");
break;
};
if (len_gt( max_len )) {
sl_send_reply("513", "Wow -- Message too large");
break;
};
/* ********* RR ********************************** */
/* grant Route routing if route headers present */
if (loose_route()) { t_relay(); break; };
/* record-route INVITEs -- all subsequent requests must visit us */
if (method=="INVITE") {
record_route();
};
# now check if it really is a PSTN destination which should be handled
# by our gateway; if not, and the request is an invitation, drop it --
# we cannot terminate it in PSTN; relay non-INVITE requests -- it may
# be for example BYEs sent by gateway to call originator
if (!uri=~"sip:\+?[0-9]+ at .*") {
if (method=="INVITE") {
sl_send_reply("403", "Call cannot be served here");
} else {
forward(uri:host, uri:port);
};
break;
};
# account completed transactions via syslog
setflag(1);
# free call destinations ... no authentication needed
if ( is_user_in("Request-URI", "free-pstn") /* free destinations */
| uri=~"sip:[79][0-9][0-9][0-9]@.*" /* local PBX */
| uri=~"sip:98[0-9][0-9][0-9][0-9]") {
log("free call");
} else if (src_ip==192.168.0.10) {
# our gateway doesn't support digest authentication;
# verify that a request is coming from it by source
# address
log("gateway-originated request");
} else {
# in all other cases, we need to check the request against
# access control lists; first of all, verify request
# originator's identity
if (!proxy_authorize( "gateway" /* realm */,
"subscriber" /* table name */)) {
proxy_challenge( "gateway" /* realm */, "0" /* no qop */ );
break;
};
# authorize only for INVITEs -- RR/Contact may result in weird
# things showing up in d-uri that would break our logic; our
# major concern is INVITE which causes PSTN costs
if (method=="INVITE") {
# does the authenticated user have a permission for local
# calls (destinations beginning with a single zero)?
# (i.e., is he in the "local" group?)
if (uri=~"sip:0[1-9][0-9]+ at .*") {
if (!is_user_in("credentials", "local")) {
sl_send_reply("403", "No permission for local calls");
break;
};
# the same for long-distance (destinations begin with two zeros")
} else if (uri=~"sip:00[1-9][0-9]+ at .*") {
if (!is_user_in("credentials", "ld")) {
sl_send_reply("403", " no permission for LD ");
break;
};
# the same for international calls (three zeros)
} else if (uri=~"sip:000[1-9][0-9]+ at .*") {
if (!is_user_in("credentials", "int")) {
sl_send_reply("403", "International permissions needed");
break;
};
# everything else (e.g., interplanetary calls) is denied
} else {
sl_send_reply("403", "Forbidden");
break;
};
}; # INVITE to authorized PSTN
}; # authorized PSTN
# if you have passed through all the checks, let your call go to GW!
rewritehostport("192.168.0.10:5060");
# forward the request now
if (!t_relay()) {
sl_reply_error();
break;
};
}
