Cases section

low ASR and unstable numbers

Germany

The team was working the German market without proper local numbers. Some calls didn’t go through, some numbers were flagged as spam within days. ASR stayed around 45–50%.

Client quote

“We were changing numbers almost every week. After switching, the numbers hold and calls actually go through. That alone changed how the team works.”

After switching to local DID numbers and rebuilding routing through SIP:

ASR increased to 62–68% within the first month
Spam flags dropped roughly 2x
Numbers stopped burning out after a few days
The team no longer had to switch channels constantly
routing failures under load

Turkey

In Turkey, the setup couldn’t handle traffic. During peak hours, part of the calls simply didn’t go through. Failures were regular.

Client quote

“Before, we never knew if the channel would hold under load. Now we can run full volume and not worry about it breaking.”

After implementing a proper SIP setup with backup routes:

Failures dropped by about 70%
Routing holds during peak load
The team can now plan traffic instead of guessing
low ASR and spam issues

Outbound

The company used low-cost routes and numbers with poor reputation. ASR stayed around 38–42%, numbers were frequently blocked.

Client quote

“We used to lose numbers and performance at the same time. Now outbound is stable, and we don’t have to rebuild everything every few days.”

After switching to DID Global:

ASR increased to 60%+
Blocking dropped significantly
Numbers no longer need to be replaced every week
Outbound stopped randomly dropping

Your calls are dropping somewhere, let’s find where
