I've seen a lot of discussions about running rtpproxy behind NAT. The fact is that standard vanilla rtpproxy can run behind NAT without any issues (no patches required). A few things must be addressed: - the proper ports must be forwarded from the public IP to the private IP; - when calling rtpproxy_offer/answer, the second parameter must be properly populated with the external public IP for streams from public network. I hope this brings some light over this highly debated topic. Regards, Ovidiu Sas -- VoIP Embedded, Inc. http://www.voipembedded.com

RTPProxy in bridge mode with distributed kamailio (loadbalance and proxies)

by Nguyen Anh Tuan

Hi all, I have a question about Control RTPProxy in Bridge mode with distributed Kamalio topology, including a SIP Load Balance, RTPProxies and some SIP Proxies behind. SIPProxies control RTPProxy by Route [NATMANAGE]. PUBLIC IP ---- Load Balance -----> SIP Proxies | | control socket PUBLIC IP < ----- RTPProxy <-----------------| In the standalone Kamailio solution (only one SIP Server - without Load Balance), I configured RTPProxy bridge mode, works PERFECTLY!!! , BUT in the distributed Kamailio solution (LoadBalance -> Proxies) has big issue with RTP: - UA in front of NAT has only upload direction (1 way RTP) but UA behind NAT has both direction (2 ways RTP). RTP stream from UAC ------ > NAT ------ > RTPProxy Public Interface ------ > RTPProxy Local Interface -------> UAS in local area network RTP stream from UAS in local area network ------ > RTPProxy Local Interface -------> STOPs HERE!!!, NOT Transfers out The RTPProxy control is performed on the SIP Proxy (Route NATMANAGE has many cases with flags WFROCEE, WFROCEI, WFROCIE). In the case the same UA in front of NAT call (RTPProxy mode "WEE"), the call occurs normally, RTP Streams is OK on both sides, but the call in cases EI and IE has problems above. What could be going on? Thanks, Nguyen Anh Tuan

Empty location table

by Alexey Rybalko

Hello! /kamilio 4.1.0/ Can anyone suggest why "location" table is empty despite that user registration works? save("location") return positive value. kamctl shows online users but if I look into kamailio.location it's empty anytime. # ----- registrar params ----- modparam("registrar", "method_filtering", 0) modparam("registrar", "append_branches", 1) modparam("registrar", "max_contacts", 10) modparam("registrar", "max_expires", 3600) ... Other strange the strange thing is that $rU is <null>. regards, Alexey

Get duration in cnxcc:call-shutdown event

by Jayesh Nambiar

Hello, Is there a straight forward way of getting the duration of the call in cnxcc-call-shutdown event. The $DLG_lifetime returns NULL as the dialog does not exist. I dont get the value of $DLG_lifetime even in dialog:end event when the call ends through cnxcc module. Even the cdr flag of acc module doesn't get the duration and it logs, invalid values !! Currently, I am storing the timestamp in htable when the call is answered and then subtract it from the current timestamp in the cnxcc:shutdown event route to get the duration. Something like this: onreply_route[MANAGE_REPLY] { xdbg("incoming reply\n"); if(status=="200") { $sht(ts=>$ci) = $Ts; } } event_route[cnxcc:call-shutdown] { $var(duration) = $TS-$sht(ts=>$ci); sht_rm_name_re("ts=>$ci"); xlog("L_INFO", "Duration of call was $var(duration)"); } Any more correct way of doing this would be very helpful. Thanks, --- Jayesh

nathelper and TCP

by Alex Balashov

Hi, fix_nated_contact() and fix_nated_register() don't appear to change the Contact at all when the source of the message is TCP. I log the value of $ct before and after, and there is no change. Kamailio tries to send to the original private IP, as well. The transport=TCP attribute is present in the Contact header in all cases. Is there something I should know about how to make these functions work with TCP? If not, what's the solution? Thank you, -- Alex -- Sent from my mobile, and thus lacking in the refinement one might expect from a fully fledged keyboard.

In the address table, you can set the tag column to a value that you check in config and decide what to do further with routing. For example, the tag can be the LCR id or dispatcher setid. You don't need to restart with above solution, just issue mi/rpc reload commands for address and lcr/dispatcher whenever you change records in database.

Problem with calling - SL local ACK found -> dropping it!

by Ismir Saljic

Hi, i have some strange problem with calling using kamailio 3.3.3. From the same client somethimes calls work well and after 2 or 3 successful calls I get this scenario. After receiving ACK as response to 407 Authentication Required Message, kamailio drops that ACK message and I got "SL local ACK found -> dropping it!" message in debug file. After this ACK message I get also 7 INVITES from client but there is no response from kamailio. I got this problem with clients that is behind multiple NATs. Other clients works well. Any advice would be appreciated.

Asterisk and Kamailio Failover-Failback

by Rafael Carvallo

Hi everyone, currently i am running 2 Asterisk Servers that share the same dialplan and sip users, also they connect through DUNDi. Right now i need that the users on certain network register to one of the 2 servers and in case it fails, then kamailio should tell the phone to log in to the backup server. After the main server for that location is restored the phones should connect again to the main server. something like this: Location A Location B network: 192.168.1.0/24 network: 192.168.2.0/24 main asterisk server: 192.168.1.1 main asterisk server: 192.168.2.1 backup asterisk server: 192.168.2.1 backup asterisk server: 192.168.1.1 Unless there's a failover situation the phones on Location A (network: 192.168.1.0/24) should login to their main server, same with Location B , as soon the problem is fixed they should failback to their main server again, as i said both asterisk server share the same dialplan and sip-users. I don't want to let kamailio handle the user registration, i just need it to tell the phones which asterisk server should they contact based on their IP and main/backup server status. I tried to do it using DNS-SRV instead of Kamalio, it worked, but the phones never failback, also, DNS-SRV doesn't tell what server should be used based on the network the request came from. I've been trying to do this and really need help, any example would be appreciated, thanks in advance. Also i'd like to know if this is possible using H.323 protocol suit instead of SIP.

Replication problems Registration Using t_replicate ().

by Raphael Borges

*Hello,* I have two servers in kamailio duality, I am using the function t_replicate () for replication log as below: Server 1 active t_replicate ("xxx.xxx.xxx.2", "5060"); Server 2 reserves t_replicate ("xxx.xxx.xxx.1", "5060"); But when the record is replicated to the standby server the parameter received is being filled with the active server IP, where the IP would Correro UAC, registry problems generating the backup server. Example Server 1 active xxx.xxx.xxx.1 $ Kamctl ul show Domain :: location table = 512 records = 1 = 1 max_slot AOR :: 4301 Contact :: sip: 4301(a)yyy.yyy.yyy.100; transport = udp Q = Expires :: 4566 Callid :: ccd0431c-6a4c-1231-0a94-7356c4f466e6 CSeq :: 46740150 User-agent :: stepo_LITE Received :: sip: yyy.yyy.yyy.100: 5060 State :: CS_SYNC Flags :: 0 CFLAG :: 0 Socket :: udp: xxx.xxx.xxx.1: 5060 Methods :: 8159 Server 2 Reserve xxx.xxx.xxx.2 $ Kamctl ul show Domain :: location table = 512 records = 1 = 1 max_slot AOR :: 4301 Contact :: sip: 4301(a)yyy.yyy.yyy.100; transport = udp Q = Expires :: 6665 Callid :: ec7cfd42-6a7c-1231-0f94-7356c4f466e6 CSeq :: 46750472 User-agent :: stepo_LITE Received :: sip: xxx.xxx.xxx.1: 5060 State :: CS_SYNC Flags :: 0 CFLAG :: 0 Socket :: udp: xxx.xxx.xxx.2: 5060 Methods :: 8159 Tkanks Raphael
