[Kamailio-Users] function to send ACK message

by Alex R.S.M

Hi, I need kamailio proxy to reply with an ACK to 200 OK, i.e. the proxy stays in the call: UAC sends INVITE to kamailio, kamailio forward it to UAS UAS sends 180 to kamailio, kamailio forward it to UAC UAS sends 200 to kamailio, kamailio forward it to UAC AND sends ACK to UAS I was wondering what function I can use so kamailio can generate an ACK message to response to 200 OK. Apparently both t_reply () and sl_send_reply() functions create responses and not an ACK message. Thanks, Alex _________________________________________________________________ Windows Live™ Hotmail®…more than just e-mail. http://windowslive.com/howitworks?ocid=TXT_TAGLM_WL_t2_hm_justgotbetter_how…

[Kamailio-Users] new user

by Andy Nedelcu

Hey, I am new at working with SIP Servers and I was wondering if Kamailio has the same features as Asterisk. I have bought a PCI card for connecting to the phone line and I want to know how can I make Kamailio aware of this card or a simple phone modem. I use FreeBSD and the only version that I found was OpenSer 1.2. Because I love being me and I love loving her, SC BMS SRL - Departamentul IT - Nedelcu Andrei

[Kamailio-Users] Silently replying 500 ?

by Aurelien Grimaud

Hi, I have a route block which issues a t_relay(). route[1] { t_relay() ; } If this t_relay fails, is there a default reply from openser to caller ? Let me explain. In my logs, I have an incoming INVITE, followed 2 ms after t_relay by an ACK from uac. The callee never gets the INVITE. UAC -- INVITE --> openser : t_relay() UAC -- ACK --> openser I guess UAC gets a default reply from openser, I want to make sure of it. I have no ERROR in my log file. UAC logs tells that openser hang up with a server internal error (no sip trace, no sip code, just an indication of what cause could be). This is openser 1.2.0 Is anyone aware f this issue ? Could someone point me where the 5xx reply is in source code ? If it is a default reply, is there now an ERROR message before reply ? Thanks, Aurelien

[Kamailio-Users] openSER concept question

by Alex R.S.M

Hi, In a SIP environment with SIP end points (UAC, UAS) and several SIP proxy hubs including openSER, is each hub like openSER supposed to reply with an ACK to 200 OK and BYE messages coming from end points? (i.e. openSER should stay on the call) Or each hub supposed to only propagate all messages including ACKs ? Thanks, Alex _________________________________________________________________ Windows Live™ Hotmail®…more than just e-mail. http://windowslive.com/howitworks?ocid=TXT_TAGLM_WL_t2_hm_justgotbetter_how…

[Kamailio-Users] DNS unreachable

by Zappasodi Daniele

Hello, I'm testing the proxy behaviour (Openser 1.3.2) when DNS servers are unreachable and I observe that with few requests that require the DNS, I have the proxy completely blocked, while it could serve all the other methods that don't need the DNS (method with IP adddress or incoming REGISTERs). I observe that each child process remains suspended until all DNS requests are finished (NAPTR, SRV and A). If I configure two DNS server and X retransmissions after Y seconds, the child remain suspended for: 2 * X * Y * 3 seconds (3=NAPTR+SRV+A queries) Even if I set low values for X and Y (X=2 retr and Y=2 sec.) the child is suspended for a long interval: 2*2*2*3=24 seconds. Is it possible to avoid that chlidren remain suspended? Is there any configuration param that can reduce this interval? Is it possibile to introduce a little change in sip_resolvehost (check errno) in order to avoid the SRV and A queries if the NAPTR fails because the DNS servers are unreachable? ********************************************************************** The information in this message is confidential and may be legally privileged.

[Kamailio-Users] Doubt about nat=yes

by mayamatakeshi

Hello, I'm trying to understand this sample cfg: http://voip-info.org/wiki/view/OpenSER+And+RTPProxy This cfg is used as foundation for some of our cfg files here but nobody is sure about exactly how some things work. So I'm trying to clear things up. In particular, I am clueless about why there is code removing "nat=yes" from the URI and adding it to the Contact header (actually I don't know what is its meaning. I suppose this is a way of a client advertising that it is behind NAT, but I couldn't find which RFC defines this): subst_uri('/(sip:.*);nat=yes/\1/') search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes'); Is this something that always must be done when dealing with nat or it was a particular situation that the writer of the cfg had to workaround? I'm rewriting our cfg file (to be used with m4) and I'm trying to remove unnecessary things. Another thing in the cfg: in case a reinvite is issued, should not unforce_rtp_proxy be called before force_rtp_proxy is called again? Could this lead to having rtpproxy leaking resources? <http://www.kamailio.org/docs/modules/1.3.x/nathelper.html#AEN367> regards, mayama

[Kamailio-Users] Openser-Asterisk Codec conversion..

by Rawshan Iajdani

My scenario is like that.. UA----->OpenSer(Outbound Proxy)---------Register Server | | | | Asterisk(codec converion)---------------------- The UA will register to Register server through outbound proxy OpenSer. When UA makes call it first comes to Openser, OpenSer should route the media to Register server through Asterisk for codec conversion. OpenSer will not hold any User account rather it will act as a proxy. The way I am thinking.. Openser could be used as outbound proxy that's fine. If it were used as outbound proxy, can it also route the media? In the asterisk side I may need username/password pair of UA to dial to Register Server in the second leg. Can I read the User/Pasword from Openser after UA is registered to OpenSer. I can have both OpenSer and Asterisk to reside on the same machine with different IPs so they can access the database if required..
