Set up outgoing calls through Binotel from Azerbaijan using a Ukrainian IP

The communication issue has been resolved and the VPN setup was successful.

The client clearly described the task, provided detailed specifications and necessary information about the current configuration. They respond quickly to questions and are open to remote access for diagnostics. The project is related to SIP telephony, VPN, and network configuration, with requirements stated clearly, which simplifies assessment and execution of the work. I recommend collaborating with them.
