Number Translation Not Work

Issue:

Pre-routing called number translation rule does not work. OSPrey returns 503.

Troubleshoot:

For this case, OSPrey SIP response code, 503, is more meaningful. From either OpenSIPS log or OSPrey log, the issue can be found that OSPrey routing feature is disabled. It is a common issue for a new installed OSPrey.

Solution:

Enable OSPrey routing feature.
