I’m here at a complete loss, I’ve been running an iso install of AsteriskNOW 22.214.171.124 for over a month.
We’ve been having constant dropped calls at set intervals:
It typically happens on conference calls.
A TCP dump hints at it’s our server causing the BYE.
I’ve tried rebuilding Dahdi_dummy - it appears to be getting over 99% accuracy on dahdi_test
I’ve removed all hardware modules from the modprobe.d file (it still complains about a line starting with ‘options’)
I’ve done the Session-timers=refuse in sip_custom.conf
I’ve called our trunk provider. its definitely us causing the hangup.
I’ve reinstalled 3 times, on 3 different server blades.
I’ve switched out all 20 phones
I’ve switched out PoE switches twice
I’ve tested all wiring.
I’ve swapped modems.
I’ve done line tests with the ISP.
and I’ve pulled out most of my hair.
Should a guru pass by this thread, could you please give me some ideas on how to get this thing fixed?
My favorite user quote to this point, said in a loud, angry, and frustrated tone was “The Telephone was perfected in 1931, why is this so hard?!”
