When i trying to register Xlite on server i got error 483 Too many Hops why is there any domain related problem or something else when i remove name server in /etc/resolve.conf i got Timeout error My --------- ser.cfg # $Id: nat-mediaproxy.cfg 51 2006-01-31 13:28:04Z /CN=Paul Hazlett/emailAddress=paul(a)onsip.org $ debug=7 fork=yes log_stderror=yes listen=192.168.104.20 # INSERT YOUR IP ADDRESS HERE port=5060 children=4 dns=yes rev_dns=no fifo="/tmp/ser_fifo" fifo_db_url="mysql://root:tulip@localhost/ser" loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/uri.so" loadmodule "/usr/local/lib/ser/modules/uri_db.so" loadmodule "/usr/local/lib/ser/modules/domain.so" loadmodule "/usr/local/lib/ser/modules/mediaproxy.so" loadmodule "/usr/local/lib/ser/modules/nathelper.so" loadmodule "/usr/local/lib/ser/modules/textops.so" modparam("auth_db|domain|uri_db|usrloc", "db_url", "mysql://root:tulip@localhost/ser") modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("nathelper", "rtpproxy_disable", 1) modparam("nathelper", "natping_interval", 0) modparam("mediaproxy","natping_interval", 30) modparam("mediaproxy","mediaproxy_socket", "/var/run/mediaproxy.sock") modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-clients") modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-clients") modparam("usrloc", "db_mode", 2) modparam("domain", "domain_table", "domain") modparam("domain", "domain_col", "domain") modparam("usrloc|registrar|auth_db|avpops|group", "use_domain", 1) modparam("registrar", "nat_flag", 6) modparam("rr", "enable_full_lr", 1) route { # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops");

[OpenSER-Users] [CPL] Is possible to group <not-present> and <otherwise>?
by Iñaki Baz Castillo 24 Dec '07

24 Dec '07

Hi. The following script doesn't proxy to "sip:voicemail@domain" if no "Subject" header exits: <cpl> <incoming> <string-switch field="subject"> <string contains="hello"> <reject status="reject" reason="Subjet = hello" /> </string> <otherwise> <location url="sip:voicemail@domain" /> <proxy /> </location> </otherwise> </string-switch> </incoming> </cpl> For that I need to add <not-present> and clone <otherwise> content: <cpl> <incoming> <string-switch field="subject"> <string contains="hello"> <reject status="reject" reason="Subjet = hello" /> </string> <not-present> <location url="sip:voicemail@domain" /> <proxy /> </location> </not-present> <otherwise> <location url="sip:voicemail@domain" /> <proxy /> </location> </otherwise> </string-switch> </incoming> </cpl> Is there any way to group <not-present> and <otherwise>? -- Iñaki Baz Castillo <ibc(a)aliax.net>

[OpenSER-Users] [CPL] subfield="tel" without "user=phone" parameter?
by Iñaki Baz Castillo 24 Dec '07

24 Dec '07

Hi, in order to match a callee URI as a telephone number (discarding punctuation and separator characters) I should user "tel" as "subfield" value, but this is only valid if "user=phone" parameters exists in the matching URI. RFC 3880 says: The "tel" subfield is defined to be the "user" part of the URI, with visual separators stripped, if the "user=phone" parameter is given to the URI, or if the server is otherwise configured to recognize the user part as a telephone number. Is there any way OpenSer CPL module to recognize "From" user part as telephone number even if no "user=phone" parameter exists? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Maybe I haven't understood the meaning of this > "recurse" parameter? or could it be a bug? Yes, a bug of mine XD For this feature working I must set a CPL parameter ("0 = dissable" by default): modparam("cpl-c","proxy_recurse",2) Now it works :) -- Iñaki Baz Castillo <ibc(a)aliax.net>

[OpenSER-Users] [CPL] recurse="yes" doesn't work ?
by Iñaki Baz Castillo 24 Dec '07

24 Dec '07

Hi, I try to set "recurse" parameter in order to automatically proxy the call to "Contact" URI present in a 302 response from called UAS: <lookup source="registration"> <success> <proxy timeout="8" recurse="yes"> </proxy> </success> </lookup> Now I set a redirection in the called UAS so it replies a 302. Reading RFC 3880 I assume that the proxy should create a branch to the 302 "Contact" URI instead of passing the 302 to the callee: 6.1. Proxy [...] The second optional parameter is "recurse", which can take two values, "yes" or "no". This specifies whether the server should automatically attempt to place further call attempts to telephony addresses in redirection responses that were returned from the initial server. [...] But in fact, the 302 arrives to the callee as if not "recurse" parameter exists. Maybe I haven't understood the meaning of this "recurse" parameter? or could it be a bug? Thanks for any explanation. Best regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

[OpenSER-Users] SIP alternate port, cross connect with 5060 port
by Raju Abhyankar 24 Dec '07

24 Dec '07

Hello, I have setup openser (1.1.1-tls) to talk to our UA's on port 5060 and some UA's on port 4800 (as provider blocks 5060). I am using Mediaproxy (1.9.0). Currently the following works: 1. UA using 5060 makes call to UA using 4800: Phone bell rings and audio two way no issues. 2. UA using 4800 makes call to UA using 5060. Phone bell rings but no audio in either direction All UA's use RTP port 5004. What can I add to the following loose route section so that I can make "2" work above. My loose route section in openser is: ##################################################### listen= udp:XXX.XXX.XXX.XXX:5060 listen= udp:XXX.XXX.XXX.XXX:4800 # Loose route section if (loose_route()) { if ((method=="INVITE" || method=="REFER") && !has_totag()) {(20) sl_send_reply("403", "Forbidden"); break; }; if (method=="INVITE") { (21)if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); if (client_nat_test("3") || search ("^Route:.*;nat=yes")) { setflag(6); use_media_proxy(); }; }; route(1); break; }; ##################################################### Please do provide if there is a solution to this issue. Your inputs appreciated. regards, Roger
