FAQ
Do I need a dialer if I make under 30 calls a day?
Probably not in pure-outbound terms. But JustCall isn't really an "outbound dialer" — it's an omnichannel phone system. Even at 10 calls a day, the AI Voice Agent (answers your inbounds while you're busy) + SMS automation (renewal reminders, quote follow-ups) earn the subscription back. If your day is purely outbound and under 30 dials, skip both.
Can I use my existing phone number?
Yes — both support number porting. JustCall typically takes 5–7 business days; Kixie similar. Your old provider keeps service running during the port window; cutover is automatic when porting completes.
How do these integrate with GoHighLevel or Agent CRM?
JustCall integrates natively with GoHighLevel and via Zapier with Agent CRM. Kixie has fewer native CRM connectors — most are via Zapier. If your CRM is one of the above, JustCall is the cleaner handoff.
Is the AI Voice Agent worth $99/mo for a solo agent?
If it captures even one warm lead that would have hit voicemail, yes. The math: one bound homeowners deal at $1,500 premium = ~$150–$200 commission to the agent. The AI Voice Agent costs $99/mo. One captured deal in 12 months pays for the entire year of the add-on. Most solo founders capture more than that.
Why isn't Mojo Dialer / Aircall / RingCentral on this list?
Mojo Dialer is a pure outbound tool with weaker AI than Kixie at a similar price — Kixie is the better pick if you want outbound-only. Aircall and RingCentral are enterprise PBX systems — overkill and overpriced for solo and small business agencies. Both target call centers and enterprises with full-time admins.
Do I need both a CRM and a dialer, or does my CRM do calls?
Your CRM probably has basic click-to-call. That's fine for occasional dialing — not for a founder doing real outbound or running AI voice flows. Use the dialer for the call work, push everything back into the CRM for the relationship history. The two together = full stack.
