Hi, I was wondering if Kamailio can support FQDN endpoint which resolves to multiple IPs, checks if the first IP is not reachable, try the next one in the list. Thanks, AL

Hello community, After a while, I finally got the connection from my Kamailio server to MsTeams and I can validate that the connection to MsTeams is in AP. [root @ kamailio-server kamailio] # kamcmd dispatcher.list | egrep "URI | FLAGS" URI: sip: sip.pstnhub.microsoft.com; transport = tls FLAGS: AP However, from the admin panel of MsTeams (Direct Routing) I see that the connection to my sbc "sbc.netvoiceperu.com" is with TLS connectivity status in "Active" but the SIP options status is in "Warning". I have made calls from MsTeams thinking that the SIP options status would change to "active" but it is still in "Warning" state. On the other hand, I have enabled a siptrace in Kamailio and verify that the SIP OPTIONS from kamailio are being sent in the following format to MsTeams. OPTIONS sip: sip.pstnhub.microsoft.com; transport = tls SIP / 2.0 Via: SIP / 2.0 / TLS 161.35.44.66:5061 ;branch=z9hG4bKea07.52224687000000000000000000000000.0 To: <sip: sip.pstnhub.microsoft.com; transport = tls> From: <sip: sbc.netvoiceperu.com>; tag = d3569c818b500aeb8c373426e76c2884-81763c71 CSeq: 10 OPTIONS Call-ID: 13ea237a751e0c48-9148(a)161.35.44.66 Max-Forwards: 70 Content-Length: 0 User-Agent: kamailio (5.4.0 (x86_64 / linux)) As you can see, the SIP OPTIONS sent from Kamailio to MsTeams does not contain the "Contact" field, which in theory said "Contact" field should have been added by Kamailio according to the configuration added in kamailio.cfg event_route [tm: local-request] { sip_trace (); if (is_method ("OPTIONS") && $ ru = ~ "pstnhub.microsoft.com") { append_hf ("Contact: <sip: sbc.netvoiceperu.com: 5061; transport = tls> \ r \ n"); } xlog ("L_INFO", "Sent out tm request: $ mb \ n"); } As additional information, I inform you that I also managed to observe the SIP OPTIONS that MsTeams sends to Kamailio. OPTIONS sip: sbc.netvoiceperu.com: 5061; transport = tls SIP / 2.0 FROM: <sip: sip-du-a-eu.pstnhub.microsoft.com: 5061>; tag = f1bdeb5f-662f-4544-a436-e9aa9ad78da4 TO: <sip: sbc.netvoiceperu.com> CSEQ: 1 OPTIONS CALL-ID: c47e2782-16c3-49cb-8931-24e9709d260a MAX-FORWARDS: 70 VIA: SIP / 2.0 / TLS 52.114.75.24:5061;branch=z9hG4bK48b0e6be CONTACT: <sip: sip-du-a-eu.pstnhub.microsoft.com: 5061> CONTENT-LENGTH: 0 USER-AGENT: Microsoft.PSTNHub.SIPProxy v.2021.1.15.7 i.EUWE.10 ALLOW: INVITE, ACK, OPTIONS, CANCEL, BYE, NOTIFY However I don't see the 200 OK SIP responses from Kamailio to MsTeams. I think this may be the reason why I see the SIP OPTIONS status in "Warning" from the MsTeams panel. Maybe the contact field is not being added in the SIP OPTIONS messages that Kamailio sends to MsTeams and for that reason I don't see 200OK responses from MsTeams. Could you help me solve this please.

Version 5.4 contact rewrite/restore functions docs?

by Dmitry Sytchev

Hello! In 5.4 release announce there is a line about contact rewriting. "new Contact address encoding/decoding functions – replace/restore Contact address with SIP server address, by encoding/decoding old address in a parameter" Where can I find some documentation or examples about NEW functions? At present we handle this task exactly the same way via parameters manually. It is kinda verbose and hard to understand. Maybe new functions will simplify this. Please advise! Thanks! -- Best regards, Dmitry Sytchev, IT Engineer

tracking usrloc clean

by Michal Popovic

Hi All, I would like to ask you if there is any way how to track usrloc location cleaning operation with some event route, so I can broadcast the change with for example kafka message. If no, how do you keep track of online/offlice status of the user? I am trying to avoid using change data capture in mysql proxy for location table. Michal
