Five failures not found in lab testing

Going live confidently with voice over LTE (VoLTE) services imply a lot of pre-testing to ensure that subscribers get the quality of experience they expect. But even after in-depth testing in the lab, failures show up, calls are dropped and networks go down.

Here are five common failures that service operators face in live networks despite pre-testing in the lab:

1. Some subscribers are unable to access voice and data services
2. Unexpected number of dropped calls
3. Call quality cannot be maintained
4. Service-level agreement mismatch
5. Network couldn’t handle calls at only 55% of its capacity

Why do failures still pop up despite the most thorough lab testing?

The main reason is that geo-redundant production networks with multiple vendors and multiple applications and technologies have different configurations and dimensions from the lab network. There is no other way around it: testing the production network is key to avoid unpleasant surprises in your live network.
