Zoiper + VoIP/SIP Setup for US & Canada Outbound Calling

I am looking for an experienced VoIP/SIP specialist to set up my Zoiper system for outbound business calls to the United States and Canada. I am located outside the US and need a simple, reliable setup that allows me to make business calls through Zoiper using a legitimate US local phone number. What I Need • Recommend a suitable SIP/VoIP provider for my use case • Help me obtain and configure a US local phone number • Connect the SIP/VoIP account to Zoiper • Configure outbound calling to US and Canadian numbers • Configure caller ID correctly so my US business number is displayed • Configure incoming callbacks to the same US number if supported • Configure SIP credentials, server/proxy and necessary network settings • Make sure US/Canada number formatting works correctly • Test incoming and outgoing calls • Check call quality and troubleshoot any audio, NAT, SIP or connection problems • Make sure the final setup is stable and ready for daily business use Important This will be used for legitimate B2B sales outreach. I want a straightforward setup. I do not need a complicated PBX or call-center system. The final result should be: Open Zoiper → enter a US/Canadian phone number → call → prospect sees my legitimate US business number → prospect can call the number back. Ideal Freelancer You should have experience with: • Zoiper • SIP/VoIP • US DID/local phone numbers • SIP trunks/providers • Caller ID configuration • International VoIP setups • NAT/firewall troubleshooting • US & Canada outbound calling Experience setting up Zoiper specifically for international users calling US businesses is a major plus. When Applying Please answer these questions: 1. Have you configured Zoiper with a SIP/VoIP provider before? 2. Which VoIP provider would you recommend for someone outside the US who needs a US number and outbound calling to the US & Canada? 3. Can you configure both outbound caller ID and incoming callbacks? 4. Have you worked with US DID numbers before? 5. What access/information would you need from me? 6. Approximately how long would this setup take? Please do not apply if you only have general IT experience. I am specifically looking for someone experienced with VoIP, SIP and Zoiper.
