LUA - UAC package implementation
by Daniel Ciprus 11 Apr '14

11 Apr '14

Hi, How much of UAC package is implemented in LUA embedded module ? According to wiki seems like only "sr.uac.replace_from" is implemented. My goal is to "emulate" 3rd party registration by using UAC and LUA meaning that I will have to recreate register, tweak existing attributes and send it over to application server to process. thanks Dan -- Daniel Ciprus Integration engineer http://www.acision.com 9954 Mayland Dr Suite 3100 Richmond, VA 23233 USA T: +1 804 762 5601 E: daniel.ciprus(a)acision.com<mailto:daniel.ciprus@acision.com> ________________________________ This e-mail and any attachment is for authorised use by the intended recipient(s) only.

about tls client certificates
by Juha Heinanen 11 Apr '14

11 Apr '14

while doing some tls tests, i noticed that if tls.cfg has a section like this [server:default] verify_certificate = no require_certificate = no tls_method = SSLv23 private_key = /etc/sip-proxy/certs/sip-proxy/key.pem certificate = /etc/sip-proxy/certs/sip-proxy/cert.pem ca_list = /etc/ssl/certs/cacert.org.pem then client does not give its certificate to kamailio server during tls connection setup even if it had one. if i specify: require_certificate = no then client sends its certificate to kamailio server, but if another client does not have a client certificate, then it cannot connect at all. one way to solve this would be making kamailio listen on two tls ports, one for clients that are required to present a a certificate and another port for clients that do not have a certificate. unfortunately, it is not possible to add a mask to ip address in tls.cfg section like this: [server:0.0.0.0/0:5062] does anyone have a solution to this problem (other that running two kamailio instances)? -- juha

SDP c= IP doesn't get rewritten
by Daniel Ciprus 11 Apr '14

11 Apr '14

All, I am facing problem with rewriting SDP part of the INVITE, in particular following is in my configuration: #!subst "/RTP_INT_ADDR/10.96.173.15/" #!subst "/RTP_EXT_ADDR/168.7.24.17/" #!subst "/BOT_RTP_ADDR/10.96.173.52/" subst_body('/RTP_INT_ADDR/RTP_EXT_ADDR/g'); subst_body('/BOT_RTP_ADDR/RTP_EXT_ADDR/g'); and this is what I ended up with: c=IN IP4 10.96.173.15168.7.24.17 Apparently 2nd rule doesn't work rewrite, it's doing append instead. What I want to achieve is : if SDP part contains BOT_RTP_ADDR -> rewrite it. In case SDP part contains RTP_INT_ADDR-> rewrite it, so 2x if. I have tried to use sdpops module, it's coring in my case and I have a reason to not upgrade, I just can't. Any other ideas how to handle my problem ?

Disjoint REGISTER and INVITE username/uri sets
by James Cloos 10 Apr '14

10 Apr '14

Given a proxy where the only registrations will be next-hop pbxes, where those names will not be INVITEable, what is the ideal way to tell kama the list of accepted usernames and authentication info for REGISTER? It is important to ensure that any INVITE to any of the REGISTERable usernames 404s. Thanks, -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 1024D/ED7DAEA6

carrierroute prefix regex?
by Igor Potjevlesch 10 Apr '14

10 Apr '14

Hello, I'm wondering if we can set into < scan_prefix > an entrier with regex like : 3[0-9]{3}? If not, what would be the best module to manage in a DB the prefix that can be composed by SIP clients before call cr_route? Something equivalent to a dialplan I guess. Thanks for your feedback. Regards, Igor.

Hi, Not sure if this is a fair question. But how do you compare your call processing engine against Cisco's Call Manager? Appreciate your time. Marjorie Lawrence Global Wireless Networks, Inc.

how to track down issue with shared lines
by mark li 10 Apr '14

10 Apr '14

I have a scenario where calls that are transferred to a shared line doesn't trigger the "in use" light to show up on both phones that have the shared line. but when i make an outgoing call, let's say, using the shared line, the "in use" light lights up on both phones that have the shared line. Phone - polycom 650s. Just a noob with SIP, kamailio and telecom, so not sure where to start debugging. Any suggestions would be appreciated. thanks in advance for your time.

Load fr_inv_timer from DB
by Igor Potjevlesch 10 Apr '14

10 Apr '14

Hello, I try to set the "fr_inv_timer" dynamically from DB. Under 60s it works fine. But I can't set more than 60s. Here are the TM parameters: # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # default retransmission timeout: 30sec modparam("tm", "fr_timer", 5000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 60000) Here are the instructions to set dynamically: avp_db_load("$ruri/username", "$avp(s:inv_timeout)/usr_timeout"); t_set_fr($avp(s:inv_timeout)*1000); Is there anything wrong? Regards, Igor.

topoh and onhold reinvites
by Daniel Tryba 10 Apr '14

10 Apr '14

I'm having some trouble with kamailio that uses the topology hider module and an incoming call being put onhold by the caller. The INVITE containing the sdp a=sendonly is to the 172.19.162.1 (the topoh mask_ip) contact header from the 200 OK to the initial INVITE. U 109.235.36.178:5060 -> 109.235.32.40:5060 INVITE sip:172.19.162.1:5060;line=pcs- mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*;user=phone SIP/2.0. This is handled within dialog (has_totag() && !loose_route()), which in the default config ends in a sl_send_reply("404","Not here") Explicitly handing INVITE (just relaying), results in the INVITE being sent to 172.19.162.1 (which doesn't exist) U 109.235.32.40:5060 -> 172.19.162.1:5060 INVITE sip:172.19.162.1:5060;line=pcs- mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*;user=phone SIP/2.0. How to get this INVITE to the actual destination? To get the same result for the INVITE as for the ACK to the 200 OK? U 109.235.32.40:5060 -> 109.235.36.178:5060 SIP/2.0 200 OK. ... Contact: <sip:172.19.162.1;line=pcs- mp4KWiTsxRmtEAM3WGysx7y3xGnoxAxtuAxSuA7KEsktxGZKWgQfZD6smqlf9Gttzjy*>.

Hello Everyone, How I can specify ldap CA cert in ldap configuration ? The directive ca_list bellow is ignored. [07/Apr/2014:13:40:37 -0400] conn=20 op=-1 fd=70 closed - Peer does not recognize and trust the CA that issued your certificate.

Current config ldap_server_url = "ldaps://ds389.network.com" ldap_bind_dn = "uid=adm,ou=People,dc=network,dc=com" ldap_bind_password = "password" authtype = simple tls = on ca_list = /etc/kamailio/cert/ca-cert_ldap.pem
