[asterisk-users] server unresponsive

[Daniel - Asterisk]

Hi,

I had some problems with sip peers losing connection suddenly without real
network issues. In my case, it was useful to refresh the table used for
real time configuration, we made an script for Postgres like this

PGUSER=user PGPASSWORD=password vacuumdb --full  --table 'sip_buddies'
asterisk_db

Greetings,

Elder D. Arohuanca
