FAQ
Can you help if my A2P 10DLC campaign was rejected by Twilio, OpenPhone, or RingCentral?
Yes. I can review the rejection reason, verify your business information, update campaign details, improve message samples, and resubmit the registration according to carrier requirements. Approval is not guaranteed since carriers make the final decision, but I can significantly improve compliance.
My SIP trunk shows registered, but calls still fail. Can you fix that?
Yes. A registered SIP trunk does not always mean calls will work properly. I can troubleshoot routing, authentication, codecs, DID assignments, outbound rules, inbound routes, and provider-side configuration issues causing failed calls.
Can you configure VoIP.ms, Twilio, Telnyx, or custom SIP providers with 3CX or Asterisk?
Absolutely. I work with major SIP providers including VoIP.ms, Twilio, Telnyx, Flowroute, Bandwidth, and many custom SIP providers. I can handle trunk setup, DID routing, failover configuration, and call flow optimization.
Why do I have one-way audio or no audio during calls?
This is usually caused by firewall, NAT, SIP ALG, RTP routing, or port forwarding issues. I will diagnose the network path and PBX configuration to restore proper two way audio.
Can you migrate my phone system from another PBX to 3CX?
Yes. I can assist with migrations from Asterisk, FreePBX, RingCentral, Grasshopper, and other VoIP platforms to 3CX, including extensions, IVRs, ring groups, SIP trunks, and call routing configuration.
Do you provide remote support without needing full server access?
In many cases, yes. Depending on the issue, I can troubleshoot using screenshots, logs, temporary access, or remote sessions. For advanced PBX or network issues, administrative access may be required.
Can you improve call quality and reduce choppy or dropped calls?
Yes. I can analyze network performance, bandwidth usage, codecs, QoS settings, jitter, packet loss, and PBX configuration to identify the root cause of poor call quality.
Can you set up a complete business phone system from scratch?
Yes. I can deploy a complete solution including 3CX, SIP trunks, IVR menus, call queues, ring groups, voicemail, remote extensions, mobile apps, DID numbers, and call center features based on your business requirements.
