Hi guys, we run fusionPBX on AWS with an end user via grandstream ht801 ATA. She is US based and complaining about excessive Post Dial Delay (PDD) - meaning she dials the number she wants to connect to...then hears silence for 4, 5, 7, sometimes 10 seconds, then hears the ringback tone begin. We use BulkVS as our main provider for outgoing, however also use Alcazar and can switch to others.
I have a VoIP phone on my desk connected to the same and am experiencing the same issue. [login to view URL]
we need to:
1. be able to measure the PDD
2. understand what is causing it to be so excessive
3. correct it - forcing a ringback to 'cover' the gap is acceptable if not other solution
You can work with our SysOp, Harold, and he'll provide access and whichever information you need.
