Does DMQ auto-discover cluster members + how?
by George Diamantopoulos 09 Jun '20

09 Jun '20

Hello all (again), When running dmq.list_nodes on one of my production kamailio servers, I get several entries corresponding to staging instances of kamailio. These staging instances are located on separate broadcast domains (different VLANs), and none of them are configured in the notification_address parameter for the dmq module. How do they end up there, and how do I get rid of them? Thanks! George

RTPProxy Traversal for all Calls
by Mike B 09 Jun '20

09 Jun '20

All, Hopefully a quick answer on this one. I am looking for away to have all traffic traverse the RTP relay, not only NAT. Thinking there should be an easy way to do this with RTPPROXY but haven't been able to figure it out. Using Kamailio 5.3 with RTPProxy 2.2 Thanks, Mike

Re: [SR-Users] Issue of calls drop 32s

Hi Alex, Thanks for your reply. ICE/STUN haven’t been activated by our clients. All transmission traffic pass through a proxy server. Below is the screenshot of a normal call process.

The server should not be forwarding such an ACK "to itself"; this suggests that its Request URI may be improperly constructed (it should be equivalent to the remote Contact URI of the callee in the 200 OK message), or that its Route headers are somehow incorrect (they should mirror the Record-Route set in the 200 OK). -- Alex On Wed, May 13, 2020 at 04:07:16PM +0000, Rex Lin (林昱頡) wrote: > Hi, > > > It’s weird that the calls always drop after 32s while the callee is using public ip.

kamailio 522 S-CSCF failing to start
by Martin W Woscek 08 Jun '20

08 Jun '20

Hello, There are times that our S-CSCF module just wont start. I’ve tried correlating the issue with some operation such as not de-registering an IMS client (Boghe or imsdroid) prior to shutting down the Kamailio server. But this isn’t always the case. Being that we are running this an a Ubuntu Virtual Machine, simply overwriting the image with a backed up VM is the temporary solution. I’ve dropped and created the db for S (kamdbctl) and rearranged the order of loading the presence module with same result. Status of the S-CSCF daemon on failure to start: # systemctl status kamailio_scscf ● kamailio_scscf.service - LSB: Start the Kamailio SIP proxy server Loaded: loaded (/etc/init.d/kamailio_scscf; generated) Active: inactive (dead) Docs: man:systemd-sysv-generator(8) Jun 08 08:22:55 ubuntu /usr/local/sbin/kamailio[16511]: INFO: cdp [cdp_mod.c:255]: cdp_exit(): CDiameterPeer child stopping ...

Hi everyone, I use kamailio and have some problem, need support. My scenario: - Kamailio ( x.x.x.x ) --> SIP provider (y.y.y.y) When i callout, SIP INVITE have 2 Record Route (1 x.x.x.x , 1 127.0.0.1) and 2 Via (1 x.x.x.x , 1 127.0.0.1), SIP provider reject it. I try to enable topos, SIP INVITE now have 1 Record Route x.x.x.x , 1 Via x.x.x.x. Everything look ok but Contact be masked like <sip:abcdefghijk@x.x.x.x> and SIP Provider reject it. Any one know how to have Contact as <sip:0123456789@x.x.x.x> where 0123456789 is our SIP number.

Hi, Thanks for your reply! What do you mean by "freezing operation system"? Can I manually reproduce stalled transactions? I tried to send SIGSTOP to a group of Kamailio processes while the transaction is live. The idea is to freeze processes for a while, then continue to work, so that by this time the transaction deletion time was missed. But after a few seconds, the transaction is still cleared.
