CRM Telephony Integration & Masking Expansion

**Title:**
Add Phone Number Masking + VoIP Click-to-Call Integration to Existing CRM

**Description:**

We already have a working financial CRM platform for managing leads and sales agents. We need a developer to add **phone number masking and click-to-call integration with our VoIP provider (Squaretalk or similar).**

**Important:**
This is NOT a full CRM build. The platform already exists. Only telephony integration and phone masking is required.

**Scope of work:**

• Mask lead phone numbers in the UI (agents should not see full numbers)
• Implement click-to-call button
• Integrate VoIP API (Squaretalk preferred)
• When agent clicks call:

* System triggers call via API
* Agent gets call
* Lead gets call
* Calls connect (bridge)

• Store real numbers securely in backend
• Log calls in CRM

**Security requirement:**

Agents must NOT be able to:
• See full phone numbers
• Copy numbers
• Access numbers via inspect element
• Access numbers via API calls

**Technical tasks:**

• Backend API integration with VoIP
• Frontend call button
• Phone masking logic
• Call event handling
• Documentation

**Requirements:**

• Experience with VoIP integrations (Squaretalk, Twilio, Plivo, etc.)
• Backend development experience
• API integration experience
• Security best practices

**Nice to have:**

• Squaretalk API experience
• CRM experience
• Call tracking experience

**To apply answer:**

1. Which VoIP systems have you integrated?
2. Have you implemented click-to-call before?
3. Estimated hours required?
4. Tech stack you will use?

**Project size:**
Small-medium integration project.

**Start:**
Immediate.
