Hi, I have extensive experience configuring Issabel PBX systems, managing firewall rules, and troubleshooting SIP trunk integrations. I’ve worked on multiple provider migrations, including updating port rules for SIP/RTP, validating connectivity, and resolving registration or call flow issues. For your project, I will: Review and update Issabel firewall rules to match the new provider’s SIP and RTP port requirements. Run and capture the BizPhone SQ Checklist tests (Speed + VoIP) as per the provided guide. Verify LAN/WAN connectivity and SIP registration. Troubleshoot and resolve any undetermined error messages. Document all changes and test results for your records. I’ve handled similar migrations where quick, precise firewall changes and thorough connectivity testing prevented downtime during the switchover. I can start immediately and ensure your new SIP trunk is fully functional. Best regards
