Location / Registrar, TCP: Use existing TCP connection

by Benoit Panizzon

Hi List CPE behind Firewall, registering to Kamailio via TCP (or TLS). When a call is sent to the CPE, kamailio attemts to open a new TCP connection and is blocked by Firewall. Is there an option to tell kamailio to use the existing registered TCP connection?

TLS -> UDP ReInvite

by Social Boh

hello, I'm configuring Kamailio to permite calls like: UDP -> UDP TLS -> TLS UDP -> TLS TLS -> UDP Until now all is ok; the only problem is with Microsip SoftPhone. When make a call from Microsip TLS to another phone UDP, when the callee answer, Microsip send a new INVITE and Kamailio don't delete all references to SRTP so the call happens but without audio. I know I have to process the reINVITE where I do has_totag stuff but I don't know how. Regards -- --- I'm SoCIaL, MayBe

Re: sr-users Digest, Vol 213, Issue 52

by Mohamed SADIK

Hello, Thank you for your reply! I've used your suggestion to accomplish some amazing things. However, I'm having an issue when calling the *"sl.stats"* or any other procedures. I've noticed that the number of "200" responses gets incremented by 2, which is not the case when using the `*kamcmd*` tool. I suspect that this may be due to jsonrpc using *http/https*, which is causing Kamailio to treat it as a "200" response code. Could you advise on how to avoid this issue? Is there any further configuration that needs to be done? Best regards.

Using jsonrpc_dispatch in xhttp:request - is it possible to restrict the RPC that can be invoked ?

by Chaigneau, Nicolas

Hello, I'm using jsonrpc_dispatch in a "xhttp:request" section (with xhttp and jsonrpcs modules), e.g.: event_route[xhttp:request] { if ($hu =~ "^/RPC") { jsonrpc_dispatch(); exit; } xhttp_reply("404", "Not Found", "", ""); exit; } This works, but I would like to restrict the RPC functions that can be invoked this way. Any advice on how I could do that ? The xhttp module provides "url_skip" and "url_match" but this is not useful because in the URL I only have something like "RPC". And the method is in the JSON body. I could parse the JSON body before calling jsonrpc_dispatch, but it's a bit complicated (I don't know if it's feasible in Kamailio script ?), and seems redundant because jsonrpc_dispatch already does that... Maybe somehow this could be checked from the "void *" second argument passed to the RPC function ? Thanks. Regards, Nicolas.

Remove silo extra_hdrs before store

by Dr. Barabás Péter

Hi, I’m using kamailio’s silo module to store offline messages in it. I set extra_hdrs modparam to e.g. : ‘Resent-from-silo’ so the clients get information that the message has arrived directly (immediatelly) from the sender or it was stored offline and comes from silo. So the problem is the following: * if receiver’s socket is broken (e.g. airplane mode on mobile) and kamailio ‘thinks’ it is registered, server tries to send the message * message will be timed out and based on config it will be stored in silo. * the next step is to check if receiver is registered or not (since the client can re-register during 30sec until the message has timed out) * If client is registered, kamailio tries to send the message immediately with m_dump(). * If the receiver’s connection is still broken, the message will be timed out and store in silo. * In every store, a new ‘resent’ extra_hdrs value is appended. When extra_hdrs length reaches 1024 bytes, the m_dump will fail and it blocks the dumping of messages to the given receiver. Question: can extra_hdrs value be removed before store? Or what can be the solution not to duplicate the extra_hdrs value in some bad network situation? Peter

How to access rtpengine rtcp-metrics?

by Benoit Panizzon

Hi all I'm trying to incorporate rtcp data from rtpengine into our CDRS. So trying with the first interesting value, the average mos. modparam("rtpengine", "mos_average_pv", "$avp(mos_average)") If I understood right, to get this variable set, I need to call rtpengine_manage() on the message that terminates the call. So on an established call, that is either BYE or the 200 OK to the BYE. Right? if ($rm == "BYE") { rtpengine_manage(); xlog("L_INFO", "$cfg(route): $rm: MOSS: $avp(mos_average)\n"); } onreply_route[MANAGE_REPLY] { [...] rtpengine_manage(); xlog("L_INFO", "$cfg(route): $rm reply MOS: $avp(mos_average)\n"); } Messages pass those blocks, $avp(mos_average) is 'null' no mater what. What am I missing? In the syslog output of rtpengine I see there is rtcp data.

tcp_set_connection_lifetime => in respect to 'idle' connection?

by Benoit Panizzon

Hi List Digging further into my tcp/tls issues... Upon successful authentication I call: tcp_keepalive_enable("60", "5", "5"); tcp_set_connection_lifetime("120"); I tought, this would do to keep the connection alive. I noticed, despite keepalive packets being exchanged, kamailio is closing the connection after a bit more than 2 minutes. I am right at assuming, that tcp_set_connection_lifetime is not related to how long the connection is idle, but is counted from the SYN, no matter if keepalives were successfully exchanged? Does calling tcp_set_connection_lifetime() again restart the lifetime like for 2 more minutes like in this example? Or would I have to keep increase the value of the lifetime on each successful re-register to keep it open?
