Zadarma vs DID Global compare before you decide

Shared routes and low-cost infrastructure often lead to dropped calls, spam flags and unstable delivery.

DID Global uses local numbers and GEO-based routing to keep calls consistent as volume grows.

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

If calls don’t go through, you’re already losing revenue
