Route header in local reply
by Евгений Голей 07 May '18

07 May '18

Hi. Colleagues write how to configure the local responses to requests so that the response added the header of the Route in accordance with the record-route headers that were in the request ? Example SBC --> Kamailio REGISTER sip:domain.com SIP/2.0 Record-Route: <sip:AAA.AAA.AAA.AAA:6060;lr> Via: SIP/2.0/UDP CCC.CCC.CCC.CCC;branch=z9hG4bKae7f.474bd538e793b8bc912ce7d0c8e0bae8.0 Via: SIP/2.0/UDP S.s.s.s;branch=z9hG4bKae7f.d81efe54000000000000000000000000.0 To: <sip:000143949@… [View More]

How long time does a push take?
by Kjeld Flarup 07 May '18

07 May '18

Hello I have a question to those of You who uses push via Google or Apple to initiate calls. How long time does it usually take, before the phone gets the push and wakes up? Our experience is, that it can take from 2 to 10 seconds, and that not impressing when we are talking about telephony. -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 … [View More]

Pleasing all kinds of UACs for RTP/SRTP with rtpengine
by Sergiu Pojoga 07 May '18

07 May '18

In continuation of previous <https://marc.info/?l=sr-users&m=150730146302404&w=2>thread about none/optional/compulsory SRTP handling... I used the suggested approach of *t_reuse_branch()* in a *tm:branch-failure* detected by t_check_status("(415)|(488)") replies, with the only difference of me doing it vice-versa from the suggested mantra of offer SRTP first then fallback to RTP. It works... well, for some UACs, not so with others. The 'good' UACs happily accept an updated … [View More]

TOPOS (5.1.[23]) breaks PRACK
by Daniel Tryba 07 May '18

07 May '18

Enabling topos breaks PRACK in my simple (near default) proxy setup (attached kamailio.conf). asterisk 13 (10.0.3.147) <-> kamailio (10.0.3.87) <-> asterisk 13 (10.0.3.154) With the event route topos:msg-outgoing dropping all. The flow of messages is as expected. INVITE -> <- Ringing PRACK -> <- 200 OK With topos enabled, the PRACK doesn't get past route[WITHINGDLG] and is answered with the sl_send_reply("404","Not here"); INVITE -> <- Ringing PRACK -… [View More]

Need help with NAT Traversal - Changing INVITE OK contact to IP port to Contact in Location
by KamDev Essa 06 May '18

06 May '18

The stock cfg states definng WITH_NAT and alls good. I did exactly that. However boing with stock cfg and WITH_NAT, the Registration info in location table is perfect with the UAs external IP address and port. This is not the case with the OK that in response to an INVITE. In the Contact of the OK the private IP shows up and Kamailio just sends it off to the Carrier who obviously cannot send a ack to a private IP. Is there a step by step guide for NAT Traversal? H

by eyas barhouk 06 May '18

06 May '18

Hello Dears I'm trying to get Kamailio to log its CDRs (collected By ACC module ) to text file instead of a database so i used modparam("acc", "db_url", "flatstore:/var/log/acc") and in each time kamailio trying to write on the text file i get the error : " db_flatstore flat_new_connection() : not a directory" so could any one guide me about how i have to create the database text file "acc"? and what is the cause of the error i got ?

Carrier IP on softphone call history !!!
by KamDev Essa 04 May '18

04 May '18

I have a simple call flow for Inbound call going to an extendion carrier call ===> WITH_ALIASDB ===> extension (on Xlite) Works perfectly getting the call. Issue : - On Xlite I see the call as <TN>@<carrierIP>. I dont want my customers to know what carrier I use and also I want to be in the loop for CDR. - Hanging on either phone will not send a BYE to my server. How do I get Kamailio to be in the SIP ladder for this call? KD

Private IP in Contact Header of 200 OK back to Carrier, so no ACK - Call drop
by KamDev Essa 04 May '18

04 May '18

Scenario Carrier ===> Kamailio ===> Ext on domainINVITE ===> ====> 200 OK <== <=== Repeated because carrier pcap shows private 192.168 IP in Contact header. cfg has WITH_NAT setup. I assumed that all I need to do. What more is required to get Kamilio IP and port in 200K to Carrier? K
