VoIP and telephony troubleshooter fixing broken business phone systems fast. I set up and repair SIP trunk registration, one-way audio, IVR, and call routing on FreePBX, Asterisk, 3CX, and VICIdial. I fix Twilio and GoHighLevel SMS failures and A2P 10DLC rejections, connect AI voice agents (Vapi, Retell, ElevenLabs) to phone numbers via SIP trunk, and harden PBX against toll fraud and SIP brute-force attacks. I diagnose before I touch anything and document every change. Message me with your setup, I'll confirm scope and give a fixed price.... Saiba mais
