I will troubleshoot voip sip registration and call audio issues

Having trouble with SIP registration, failed calls, or one-way audio? I can help investigate your VoIP issue using SIP/RTP analysis, Wireshark, logs, and structured troubleshooting.

I work with Asterisk, VitalPBX, Yeastar, Grandstream, IP phones, softphones, SBCs, NAT, firewalls, and carrier connectivity.

You will receive a clear summary of findings and recommended next steps. Please contact me before ordering so we can confirm access, scope, and whether the issue is suitable for remote diagnosis.

This service covers diagnosis and documented recommendations. Configuration changes, server access, emergency work, and multi-system projects require a separate custom offer. All work must remain inside Fiverr.
