The Issue
– The client reported that they were abruptly unable to make international calls at one of the prime locations
– The client also reported an issue with their dial plan

– Our engineers asked the client to make test calls in order to run a trace.
– The team identified that the calls were not being routed through a particular trunk group.
– We checked the status of the trunk group

The Solution

– The team took approval from the client and engaged a technician at the client location to busy the first trunk group and ensured that the trunk was in service
– Engineers checked dial plan analysis and route pattern, and made necessary changes as per client requirement
