Still on a quest to find out why my repeater node is behaving badly re: audio dropouts, I decided to look with more depth at the events in asterisk. I set verbose level to 6 and saw this recurring pattern. A section of the log output to the console follows: [Mar 21 16:36:58] WARNING[818]: chan_iax2.c:10127 iax2_do_register: REGISTER-LOG: Sending registration request for '44011' [Mar 21 16:37:00] WARNING[822]: chan_iax2.c:7690 registry_rerequest: REGISTER-LOG: registry rereqquest [Mar 21 16:37:50] WARNING[815]: chan_iax2.c:10127 iax2_do_register: REGISTER-LOG: Sending registration request for '44011' [Mar 21 16:37:52] WARNING[818]: chan_iax2.c:7690 registry_rerequest: REGISTER-LOG: registry rereqquest -- Received OK from Echolink server nawest.echolink.org -- Received OK from Echolink server nawest.echolink.org -- Directory pgm done downloading(partial,compressed), 394 records [Mar 21 16:38:42] WARNING[819]: chan_iax2.c:10127 iax2_do_register: REGISTER-LOG: Sending registration request for '44011' [Mar 21 16:38:44] WARNING[815]: chan_iax2.c:7690 registry_rerequest: REGISTER-LOG: registry rereqquest [Mar 21 16:39:34] WARNING[816]: chan_iax2.c:10127 iax2_do_register: REGISTER-LOG: Sending registration request for '44011' [Mar 21 16:39:36] WARNING[819]: chan_iax2.c:7690 registry_rerequest: REGISTER-LOG: registry rereqquest After looking at it for a while, I noticed that the time delta between the "registry rerequests" and the following "do_register" is exactly 50 seconds. Is this normal? Does it really need to re-register that often or does it indicate a network problem with the Rpi's connection to the outside world? My configuration again is: Raspberry Pi 3 with DIAL RAT_RC1.img Repeater Builder RB-USB Rim Lite Interface Vertex VXR-7000 Repeater Metallic case for the Pi Modular connectors and Cat-7 cable for the interface with snap-on chokes at both ends Pi is connected to the local network via Wifi (We are prepared to move this to Ethernet, but need approval of the host to do so) Pi is connected to an external server via OpenVPN for collection of mgmt. statistics via SNMP Pi also runs Apache2 and Allmon2 Echolink is enabled (Node 746074) AllStarLink of course (Node 44011) Thanks for any insight you might be able to lend!
