[asterisk-users] Re: PSTN Calls from SI.P: buzzing and pops

[Allen Casteran]

As a follow up test, I unplugged line 1 from the Astibank and connected 
it to a butt set. Placed a call into my own office and listened to 10 
minutes of voice mail. Clean sound. No crackles or buzzing.

Reconnect the CO line to the Astribank and place same call to my office.
Listen to voicemail and hear 3 pops, buzzes in 2-3 minutes.

Ideas?
