nathelper OPTIONS ping
by Xuo Guoto 28 Mar '22

28 Mar '22

Hello all, I am trying to periodically send SIP OPTIONS to all connected WebRTC clients from Kamailio. The functionality is similar to qualify=yes of Asterisk. Following are the configuration changes I have made to get this working. #!define FLB_NATSIPPING 7 <snip/> loadmodule "nathelper.so" <snip/> # ----- nathelper params ----- modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "natping_interval", 20) modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") <snip/> # Handle SIP registrations route[REGISTRAR] { if (is_method("REGISTER")) { xlog("L_INFO", "Processing REGISTER in route[REGISTRAR]\n"); if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); # do SIP NAT pinging xlog("L_INFO", "Setting FLB_NATSIPPING\n"); setbflag(FLB_NATSIPPING); } if (!save("location")) { sl_reply_error(); } xlog("L_INFO", "Successfully processed REGISTER in route[REGISTRAR]\n"); exit; } } When the WebRTC client registers, I can see the log: Setting FLB_NATSIPPING, but SIP OPTIONS packets are not seen. I am checking it using the Chrome console, at client side as well as sipdump module in server side. Do I have to do any additional configuration? I am not posting the full config file here so that its easy to focus on the relevant parts, but can do that if needed. Thanks and regards, X.

Re: [SR-Users] Kamailio : kamctl address reload with HAProxy

Hello, please keep the list in CC – that others can comment as well. Can you actually connect from the kamailio system e.g. with mysql client? If yes, as I said – I would try to debug the issue further with network analysis tools.

t_suspend / t_continue & insert_hf
by Fuad Trle 28 Mar '22

28 Mar '22

Hello, I'm inserting some headers after getting value from http_async_query. If a call is relayed, I see them. But If I t_suspend and t_continue call (before time out), I do not see added headers. Here is flow: route(START) t_newtran(); #.. prep for query http_async_query("url","HTTP"); route(HTTP) #.. collect and using data from query insert_hf("$var(key): $var(value)\r\n"); t_store(); if (registered("location") { route(RELAY); } else { t_suspend(); exit; } route(AWAKE) t_continue(); I see that the branch index ($T_branch_idx) is 0 at start. 1 after http query, +1 if there is forking or location. +1 after t_suspend. It looks like t_continue uses a branch with index after t_suspend. I tried with t_save_lumps() to carry over changes. Any idea how to do this?

Using DNS log in
by Steve 26 Mar '22

26 Mar '22

Hello, I have a very basic Kamailio 5.4 configuration on Debian 11 with RTPProxy 2.2 behind a firewall. It works fine with the sip client logging into the server public ip address. However, the sip client is not able to log in when using a dns domain name directed to that public ip address. Is there a specific setting in the Kamailio and/or RTPProxy config files for using a dns domain name instead of a numeric ip address? Also, is there a Kamailio module that allows use of encrypted keys instead of passwords when logging in? Thanks for any info, Steve

Kamailio SCSCF forward SIP INVITE over TCP
by Weiqi Yao 24 Mar '22

24 Mar '22

Hello community, We currently have some issues with Kamailio SCSCF forwarding a large SIP UDP INVITE packet(size around 3000bytes), it got dropped somewhere in the ethernet. I tried increase the MTU size on both sides' interface and even define it on the switch port, but still no luck. So I am thinking to force SCSCF to send this INVITE over TCP, I followed this link: https://andersbrownworth.com/cms/264/, enabled naptr in SCSCF config and configured NAPTR and SRV DNS record, but the SCSCF still stop even forward it out. I think I did the DNS part right cause when I switch the NAPTR record to point to UDP it worked. Anyone have some experience with configure SCSCF forwarding SIP through TCP? BR, Weiqi
