Hangup a call after a certain time from 183

by Antonio Couto

I need to hang up a call after some seconds after received 183 provisional response but before any other SIP message. I am using "rtimer" module to set a callback on time, but how can I search for a call on transaction module in order to terminate the call? I think I am missing something to prepare the transaction data before I can use this data to terminate the call. I am thinking of storing the call-Id of all transactions to use on timeout callback, I don't know if it's possible. Thanks in advance. Antonio

issue using phonenum module

by David Escartín

Hello all we are using the phonenum_match_cn function to detect valid phone numbers, but seems there are some numbers like 576015145834 which are no detected as valid ones, $phn(ani=>valid) --> 0 $phn(ani=>ccname) --> <null> $phn(ani=>cctel) --> 0 $phn(ani=>error) --> Invalid number but using https://libphonenumber.appspot.com/phonenumberparser?number=576015145834&co… seems it gives a valid result Validation Results Result from isPossibleNumber() true Result from isValidNumber() true Result from isValidNumberForRegion() true Phone Number region CO Result from getNumberType() FIXED_LINE we are using kamailio 5.4 and libphonenumber tag v8.12.30 (also tested v8.9) the command is used with 'ZZ' cnc and passing the number with + maybe we are missing something in the configuration/setup? thanks and regards david -- <http://www.sonoc.io/> David Escartín NOC engineer *www.sonoc.io* <http://www.sonoc.io/> [image: LinkedIn] <https://www.linkedin.com/company/sonoc> [image: Twitter] <https://twitter.com/sonoc_> [image: Facebook] <https://www.facebook.com/SONOCio/> This e-mail is for the exclusive use of its recipients and may contain business secrets or other confidential or privileged information.

Get all contacts by domain

by Jose Fco. Irles Durá

Hi, I'm running a cloud infrastructure with multiple sip domains and I have some kamailio's as registrars with dmq for usrloc replication. The kamailio registrars are configured without db, so the aors are in ram. For some gui's I need to get all aors for one sip domain, If I execute ul.dump I get all aors, but I want only a few. In my situation it would be perfect to get all registrations for one sip domain in one request (memory, performance, cache at gui...) I thought I could save the registers with save("$rd") but ul.dump doesn't allow any parameter that restricts the "location" domain. Is there any solution for this? Best regards -- Jose Fco.

Use of interface name or listening socket name as DMQ server_socket

by Ben Kaufman

Kamailio allows the use of an interface name (eth0 for example), as the identifier for the listen directive. Additionally it allows assignment of a name to be used as an identifier. This can be used, as indicated in the documentation: A unique name can be set for sockets to simplify the selection of the socket for sending out. For example, the rr and path modules can use the socket name to advertise it in header URI parameter and use it as a shortcut to select the corresponding socket for routing subsequent requests. I'm wondering if there is a way to get allow either of these parameters to be used to define DMQ's server_socket parameter. This would be useful in containerization situations where the local IP address is assigned dynamically. Here's what I'm attempting: #!KAMAILIO loadmodule "tm" loadmodule "sl" loadmodule "dmq" loadmodule "textops" listen=udp:eth0:5060 name "sip5060" listen=udp:eth0:5090 name "sip5090" modparam("dmq", "server_address", "sip:dmq_quicktest:5090") modparam("dmq", "notification_address", "sip:dmq-bus:5090") modparam("dmq", "server_socket", "sip5090" ) ## Above line doesn't work, neither does the line below: #modparam("dmq", "server_socket", "udp:eth0:5090" ) modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 3) modparam("dmq", "ping_interval", 30) request_route { exit; } I get the following error during startup: 0(1) ERROR: dmq [dmq.c:241]: mod_init(): server_uri is not a socket the proxy is listening on Thoughts? I realize that I can configure and pass static networking with the containers, but I'm looking for a way to have this set on the fly - especially when testing, etc. Ben Kaufman

SIP trunk challange

by Mihai

Hello ! I have this issue with the telco provider they give the sip trunk on a private conection with private ips, the problem is that i am trying to relocate the sip trunk in remote server and I've tried though basic networking/tunnels/vpn and no go; their sbc is dropping requests and rejects if they are more via headers, they force me to use that conection and the ip allocated. The challenge is how to this is in kamailio, basically i just want to transport the trunk (similiar to a reverse proxy for web) to its new destination and from there handle everything. Any hints on how to achieve this?

Kamailio vs FreeSWITCH as SBC

by Unai Rodriguez

Dear List, I’m looking at using Kamailio as SBC. This would replace our current FreeSWITCH-based SBCs. What are your thoughts on this move? Would there be any known reasons why Kamailio would be superior to FreeSWITCH as an SBC? Thank you so much Unai Rodriguez

remove header in async processing (e.g. by http_async_client)

by Henning Westerholt

Hello, I'd like to remove headers during async processing e.g. in a route called from http_async_client(..). The usual textops functions are not working here. Adding headers could be done using something like rtjson, but it do not offer a remove header function. I could of course loop the request locally, but this is not that "nice". Any other suggestions for this case? Or just the rtjson module needs some extensions? Thank you, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/>
