Hi List Can someone please help me? I need to implement PBX Services for a customer that has 10 IP Phones at his Main site and then 20 IP Phones located over 5 Branches. My goal is to have RTP go end to end and not proxied. I had a look at the below link and tried it, but with no luck. http://kamailio.org/dokuwiki/doku.php/examples:caller-callee-behind-same-nat Here is a partial output of my kamailio.cfg file if someone would be so kind to help me. #!ifdef WITH_NAT # ----- rtpproxy params ----- modparam("rtpproxy", "rtpproxy_sock", "udp:localhost:7722") # ----- nathelper params ----- modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@x.x.x.x") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) #!endif ####### Routing Logic ######## # Main SIP request routing logic # - processing of any incoming SIP request starts with this route route { # per request initial checks route(REQINIT); # NAT detection route(NAT); # Caller NAT detection route route[NAT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(FLT_NATS); } #!endif return; } # RTPProxy control route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) { unforce_rtp_proxy(); } else if (is_method("INVITE")){ force_rtp_proxy(); } if (!has_totag()) add_rr_param(";nat=yes"); #!endif return; } Thank you in advance Kind Regards Deon

CRASH on qm_free for simultaneous calls (V3.1.0)

by Jijo

I'm observing a crash on qm_free, when we made two outgoing calls to the same number. One SIP phone receives ring back tone and the other busy tone. The back trace is shown below which shows that it is crashed in abort(). How can the condition if (f->u.is_free){ could be true? Please let me know if anybody observed this issue and let me know how to debug this isssue. f=(struct qm_frag*) ((char*)p-sizeof(struct qm_frag)); #ifdef DBG_QM_MALLOC qm_debug_frag(qm, f); if (f->u.is_free){ LOG(L_CRIT, "BUG: qm_free: freeing already freed pointer," " first free: %s: %s(%ld) - aborting\n", f->file, f->func, f->line);* abort();* } MDBG("qm_free: freeing frag. %p alloc'ed from %s: %s(%ld)\n", f, f->file, f->func, f->line);

new: pkg monitoring and troubleshooting enhancements

by Daniel-Constantin Mierla

Hello, I have committed some code to allow easier troubleshooting and monitoring of PKG usage per process. One new functions are exported by cfgutils module: - pkg_summary() - can be used to dump summary of PKG usage Btw, there was also added shm_summary() that dumps the summary of SHM usage. The kex module exports a new rpc command 'pkg.stats' that prints PKG usage metrics (used, free, real_used) per process. Here is a sample output: sercmd> pkg.stats { entry: 0 pid: 4793 rank: 0 used: 124788 free: 3813512 real_used: 380792 } { entry: 1 pid: 4794 rank: 1 used: 132740 free: 3805512 real_used: 388792 } { entry: 2 pid: 4795 rank: 2 used: 132740 free: 3805512 real_used: 388792 } The adding free to real_used values results in pkg memory size per process (4MB in this example). To get these stats, you have to compile with MALLOC_STATS enabled (this is default for Kamailio, so nothing actually to do for it). One benefit of this pkg.stats is ability to monitor usage of private memory and trigger alerts if the amount of available memory (free) for one process goes below a lower limit, useful when there is a memory leak (so you restart in time and report the problem) or the config operations for given traffic needs larger PKG size. In the near future there will be some new additions to be able to access these values also via PVs. Testing and feedback is appreciated.

Kamailio Compatability with Elastix

by Kurt Mullen

Well I finally made some progress. I have Kamailio 3.1.0 installed on one server and Elastix 2.0.3 installed on another server. The Kamailio server queries Elastix for authentication, and the SIP clients are able to register with Kamailio. However, the clients cannot call each other. Also, extensions added in the Elastix interface cannot authenticate with Kamailio. I have to manually add the users in the Asterisk database using mysql commands to get the authentication to work. I will need to use a GUI for staff to add / delete numbers. Am I way off base here? Kurt Mullen

Changing the text of reason header in CANCEL messages

by Klaus Feichtinger

Hello, I want to ask if you know any possibility in changing the text of the SIP reason header in CANCEL requests. Is the limitation still the same as described in the mail below from May 2010? For my scenario I have to use the TM module, because incoming requests from the PSTN gateway are parallelly forked to two destinations. Whenever the pending call is cancelled by the PSTN gateway the CANCEL request is still containing a reason header (Q.850;cause=16). But I would like to adapt the text of this header according RFC3326 (e.g. 'Reason: SIP ;cause=487 ;text="Request Terminated"'). The feature "e2e-cancel-reason" is working fine - the original text is copied, but no textops function can make any change..... Is there any trick possible to change the text of this header before it is handled by the proxy (e.g. in creating a spirale - change the text and forward it to the same proxy again)? Or in worst case if this is currently absolutely impossible - would this be an acceptable request for a new feature in any upcoming release of Kamailio 3.1.x? In the release 3.1.x it is still possible to store the text of an incoming reason header, so I guess it could be no problem in overwriting this text with any function...... Is anybody else interested in this feature? regards, Klaus ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Am 21.05.2010 09:26, schrieb François BERGANZ: When I use forward, it doesnt work!

TCP Overload Congestion

by Jijo

Hi Andrei, I'm observing TCP Recv buffer getting full when we are doing a load run (30cps) on Proxy with TCP. Basically the congestion is happening on the TCP connection from SIP Server to Proxy. I beleive kamailio is not processing the message fast enough, due to this congestion is occuring. Did anyone observe this behavior? How do we resolve it? Thanks Jijo

Can't Auth against Kamailio 3.1.1 - fresh install

by Graham Wooden

Hi folks, Getting ready to stage my 1.4.2 upgrade to 3.1.1 - but apparently I am missing something pretty basic here as I can't get a test subscriber registered. Turned up debug and viewed the "401 Unauthorized" repeating messages. So I combed back through the INSTALL and the various references on kamailio.org. And for full disclosure, here are the relevant steps that I have took: Did a make clean on the source and re-did the make, which looks like: make FLAVOUR=kamailio group_include="standard mysql" include_modules="carrierroute acc mi_fifo kex tmx pv siputils mi_rpc" cfg all install Added my domain into kamctlrc. Created a fresh DB, started up kamailio and added a user: [root@qa-voip-01 kamailio-3.1.1]# kamctl add testnumber testpass new user 'testnumber' added Made the appropriate changes to the default kamailio.cfg by adding in the defines. Restarted kamailio - no errors and all looked good. At this point, all indications would think that I can get the subscriber registered and get the location table updated ... But no such luck: [root@qa-voip-01 kamailio]# kamctl ul show Domain:: location table=512 records=0 max_slot=0 Any thoughts on where to look? I have confirmed that the subscriber device is using the right credentials. Using plaintext and the password is in user's row in the subscriber table. I am sure it's something pretty basic; this is my first stab at 3.1 from my 1.4 production machines. Thanks, -graham
