Signal House vs Lead Connector for Client SMS/Calling
The Core Problem
You need ONE provider per client for consistency. If outreach goes from a Signal House number but calls come from a Lead Connector number, contacts get confused.
Signal House Pros
- Much cheaper SMS for outbound (great for agency cold outreach)
- Easier A2P verification process
- Can buy numbers and manage messaging
Signal House Cons
- No native voice integration with GHL — support gives contradictory answers
- Call logging is "absolute hell"
- Mobile app has no voice option — clients can't call leads from GHL app
- API docs are bad, help center is useless
- Support agents contradict each other on roadmap features
- "Apparently either this month or next month their voice features are getting direct native integration" — unconfirmed
Lead Connector Pros
- Native GHL integration — everything works in one place
- Clients can use GHL mobile app to call leads
- Call logging works natively
- Best CRM experience for business owners
- Single number for SMS + calls = no confusion
Lead Connector Cons
- A2P verification is painful
- SMS costs higher than Signal House
Porting Numbers
- You CAN buy on Twilio, port messaging to Signal House, keep calling on Twilio
- But porting takes forever
- May need to re-do A2P after porting
- Adds complexity
Recommended Approach
- For agency outbound (cold email/SMS): Signal House for cheaper rates
- For client sub-accounts: Lead Connector for native integration
- Long-term: Reverse engineer Signal House's A2P privacy policy approach and build your own verification infrastructure
- Consider just using Lead Connector for everything to keep it simple, despite higher SMS costs
SIP Trunks Alternative
- SIP trunks are a phone provider option for developers
- Way cheaper than Twilio — numbers cost ~$1
- Worth exploring for dedicated lines at scale
