HI All.
We implemented SwitchVox PBX (ver 7, 101700) & 30 phones (D62 & D65s) last week.
Ever since we went live, some phones become randomly unreachable/unregistered for up to 30 minutes.
Here are the symptoms:
There is no pattern as to which phones will disconnect or become “unreachable” every 2 to 4 hours.
Phones are In various parts of the buildings, connected via different network paths.
POE connection stays live.
The ICMP ping to the phones stays up ( we are monitoring via Zabbix)
No argument from me there . I requested support with Digium as well , but wanted to check community forums to see if anybody has any ideas or similar situation, considering that Switchvox is based on Asterisk, and this seems more of config or networking issue , rather than specific to SwitchVox.
Also the link on Digium/Sangoma’s website to “community forum”, points here.
PS:
Sorry if I stepped on any toes , i’m new to Asterisk community .
Well I don’t have experience about your issue but possible could give a little help.
Digium D series phones could be setup through 2 ways;
. configured by DPMA or XML
. Sip standard mode
Just in case of DPMA mode it need No-cost licenses for the DPMA, and it use a different phone set up, it required license and xml template file configuration on Asterisk (you can refer for more details to https://wiki.asterisk.org/wiki/display/DIGIUM/Sangoma+D-Series+Phones ).
In the DPMA mode it could configured XML template phone log events.
log_level (error, warning, debug, information)
log_server (IPv4 address of syslog server )
log_port (port as integer )
enable_logging (1 or 0)
By this mode it could store phone log information on syslog server to give an idea what’s cause unreachable issues.
For use DPMA mode it have a complete different configuration as SIP mode and phone could only work only one mode.
In case of standard SIP mode you could look on asterisk log information on /var/log/asterisk.
Per recommendation from out Digium support contact, we went with the 2nd solution and adjusted them on the firewall.
It really depends on your firewall, some give you access to do it in GUI like Sonicwall, but we use Endian, and it’s done via CLI in it.
On endian these settings are adjusted in /etc/sysctl.conf
