Hi, Is there any way in Kamailio where I can suppress sip registration authentication. I want, Kamailio can send 200 OK for sip registration without going for 401 Unauthorized. Please tell me if you have such configuration in Kamailio. thanks Bipin

Kamailio config file String Concatenation

by George Diamantopoulos

Hello, I'm a a bit confused as to when string concatenation will work in kamailio config file. So far I have identified the following cases: Working: As part of the right hand side of an assignment: $var(x) = "string1" + "string2"; String argument of some functions: xlog("L_ERR", "string1" + "string2" + DEFINED_STRING + '\n'); Conditional Statements: if ( ru =~ "$" + "sip:" + $var(user) ) { Not Working: In string transformations (the fact that quotes is not part of the argument should give a hint though: $var(x) = $(var(y){s.replace,match,"repl1" + "repl2"}); String argument of some other functions: append_hf_value("P-Asserted-Identity", "<" + "$var(new_pai)" + ">"); lookup("location", "sip:$var(username)@" + SIP_REALM_DEFINITION)); In module parameter definitions: modparam("nathelper", "sipping_from", "sip:keepalive@" + SIP_REALM_DEFINITION) So far, I have found this to be fairly consistent, except for use within functions. For example, string concatenation works for the second argument of xlog, but not for the string arguments of append_hf_value() or lookup(). Is there anyway to know this for each function beforehand, or is my only choice to go through trial and error here? Thanks! BR, George

Routing 10 Digit Inbound call to Registered User or VM server

by KamDev Essa

I have Kamailio 5.1 installed and running with 2 extensions, 201 and 202 registered. Both extensions can call each other perfectly. Next I am workin on inbound calls. I have an inbound call from a carrier that arrives perfectly but ends up in this area of the cfg case -3: send_reply("404", "Not Found"); exit; and sends a 404 not found. How do I : - Associate the 10 digit DID to the 201 or 202? Custom table I make or is there something native to Kamailio. - Relay the call to the 201 or 202. Thank in advance KamDev

Routing inbound call from carrier to user or voice mail

by KamDev Essa

I have Kamailio 5.1 installed and running with 2 extensions, 201 and 202 registered. Both extensions can call each other perfectly. I have an inbound call from a carrier that arrives perfectly but ends up in this area of the cfg case -3: send_reply("404", "Not Found"); exit; and sends a 404 not found. How do I : - Associate the 10 digit DID to the 201 or 202? - In the cfg, check if user is registered if - yes, relay call to user - no relay call to VM server. KamDev

Auto 100 Reply

by Duarte Rocha

Greetings, I have set the auto_inv_100() parameter from the TM module so i can get automatic "100" replies to the INVITE. However, in some cases i want to reply to the INVITE with provisional responses (181 for example) and i would like that "100" could be sent before the "181". In order to achieve this, on transactions that are going to be replied with 181 i'm turning off the parameter with t_set_auto_inv(0) and the sl_send_reply("100","Trying"). Is this the best way to do this? Thanks

I am not able to make a call from kam1 SIP Registered user to kam2 SIP Registered user.

by Suresh Talasaniya

Hello, Is it possible to configure two Kamailio servers with shared registration database? Any SIP UA can be registered on any server but it must transparently call another SIP UA which can be registered on the same or on another Kamailio server. *I configured usrloc module with below params.* ## ---------- usrloc params ------------------- #!ifdef WITH_USRLOCDB modparam("usrloc", "db_url", DBURL) *modparam("usrloc", "db_mode", 3)* modparam("usrloc", "use_domain", MULTIDOMAIN) modparam("usrloc", "timer_interval", 30) modparam("usrloc", "matching_mode", 1) modparam("usrloc", "cseq_delay", 10) modparam("usrloc", "fetch_rows", 3000) modparam("usrloc", "hash_size", 12) modparam("usrloc", "timer_procs", 4) modparam("usrloc", "handle_lost_tcp", 1) modparam("usrloc", "close_expired_tcp", 1) modparam("usrloc", "db_timer_clean", 1) modparam("usrloc", "skip_remote_socket", 0) modparam("usrloc", "server_id_filter", 0) modparam("usrloc", "preload", "location") #!endif I am not able to make a call from kam1 SIP Registered user to kam2 SIP Registered user. it would be appreciable if anyone helps me to resolve the issue. Thank you! -- Regards, Suresh Talasaniya. Contact : +91-9724264776 Skype : suresh.talsaniya

Nat_UAC

by Nicolas Breuer

Hello The list, What do you think of the purpose of this function Nat_Uac_test('16') 16 - Test if the source port is different from the port in the "Via" header Correct me if I'm wrong but compare the source port of the message with the source port of the via is only valid on the initial invite ? All subsequent messages or replies don't list the UAC anywhere in the via. Thanks for your replies,
