Our FreePBX 2.6.01 / Asterisk 188.8.131.52 system is consistantly dropping calls at 10 minutes. I am hoping this is something very simple and obvious (just not to me).
It is stock, installed from an AsteriskNOW! download, with trunks from Speakeasy (I have contacted them about a timeout on their end). The phones and asterisk server are on a physical and logical subnet that uses the firewall as the gateway. We have a Sonicwall TZ-210 firewall. I have attached an excerpt from the Asterisk 'full' log with an example of a conference call that was dropped every ten minutes (asteriskfull.txt).
The phones are Linksys 942 & 941.
