best practice to re-install rtpengine after jessie to stretch upgrade?
by Juha Heinanen 15 Jun '17

15 Jun '17

I made a test upgrade from Debian Jessie to Stretch while rtpengine 5.1.1 was running on Jessie. What is the best practice to get xt_RTPENGINE module installed in the new Stretch linux kernel, since it does not happen automatically. Should I reinstall rtpengine* packages or is there some better way? -- Juha

SUBSCRIBE within
by Annus Fictus 14 Jun '17

14 Jun '17

Hello, I'm using Kamailio in a Multi Domain setting. I have a problem with SUBSCRIBE within a Dialog With the first subscribe no problem: SUBSCRIBE -> 407 Proxy Auth -> SUBSCRIBE -> 200 OK In the 200 OK the Contact header contain the Kamailio IP so when the Softphone send another SUBSCRIBE within the dialog (at the IP present on the contact header) Kamailio answer whit a 404 Not Here because I use these lines: if (is_method("SUBSCRIBE") && is_uri_host_local()) { # in-dialog subscribe requests route(PRESENCE); exit; } So, as the softphone send the new SUBSCRIBE to Kamailio IP and not the Kamailio domain, Kamailio not use this block but: sl_send_reply("404","Not here"); exit; } My question is: Why Kamailio in the Contact Header of 200 OK of SUBSCRIBE use the public IP and not the domain? Regards

Hi all, I'm trying to use the Redis database for authentication and later for accounting. I installed Redis on the server, I compiled Kamailio with ndb_redis and the module exists. When I try to start Kamailio I get following errors: 0(16737) ERROR: <core> [db.c:203]: db_bind_mod(): Module db_redis not found.
