- Industry: Consumer Goods & Services
- Company Size: Small company (11-50 employees)
- Services: Technical Assessment, HubSpot Engineering, Solution Architecture, HubSpot integrations

Summary
Lokabox overcame standard calling solution limitations and gained seamless telephony integration with their existing Siemens Unify system connected to HubSpot. Now equipped with automated call logging, contact creation capabilities, and comprehensive activity tracking, Lokabox can maximize sales efficiency while protecting their existing telephony investment.
The challenge
Growing Sales Operations, Existing Infrastructure Constraints
Administrative Time Drain on Sales Activities
Lokabox's sales team was losing valuable selling time to manual administrative tasks including dialing numbers, logging call activities, creating contacts for unknown callers, and managing call records across disconnected systems.
Standard Solution Limitations for Their Needs
Another challenge was finding calling solutions that matched their operational requirements. HubSpot's native calling tool lacked inbound call support and had minute limitations, while third-party solutions like Aircall would require abandoning their existing infrastructure investment.
Existing Telephony Investment Protection
The final issue was maximizing their current Siemens Unify telephony system investment. Lokabox had already deployed Procall desktop tools and established calling infrastructure that needed integration rather than replacement to maintain operational continuity.
Strategic Integration Rather Than System Replacement
Lokabox needed more than standard calling solutions, they required custom integration architecture that would:
- Preserve their existing Siemens Unify telephony infrastructure investment
- Automate call logging and contact creation within HubSpot workflows
- Enable both inbound and outbound call management capabilities
- Minimize administrative overhead while maximizing sales team productivity
Custom Siemens Unify integration delivering comprehensive calling functionality within HubSpot
1. Comprehensive System Analysis
We conducted detailed analysis of Lokabox's existing Siemens Unify infrastructure and Procall desktop implementation. This assessment identified integration opportunities and defined technical requirements for seamless HubSpot connectivity without disrupting established workflows.
2. Custom Integration Architecture Development
We engineered sophisticated integration connecting Siemens Unify telephony with HubSpot's contact and activity management systems. This custom development approach overcame the apparent complexity of integrating enterprise telephony systems with modern CRM platforms.
3. Automated Call Management Implementation
We implemented comprehensive call logging functionality for both outbound and inbound activities. The system automatically creates HubSpot call activities, looks up existing contacts by phone number, and creates new contact records when unknown callers are identified.
4. Sales Process Optimization Integration
We configured the integration to streamline sales workflows by eliminating manual data entry requirements. Sales representatives now focus entirely on customer conversations while the system handles all administrative aspects of call management automatically.
Custom Telephony Integration for Legacy System Modernization
We developed innovative integration architecture that connected enterprise telephony infrastructure with modern CRM capabilities. This solution demonstrated how businesses can modernize operations without abandoning existing technology investments.
- Legacy System Preservation: Maintained existing Siemens Unify and Procall infrastructure while adding modern CRM integration capabilities.
- Automated Administrative Processes: Eliminated manual call logging, contact lookup, and record creation tasks that previously consumed valuable sales time.
- Comprehensive Call Management: Enabled both inbound and outbound call activities to be automatically tracked and managed within HubSpot workflows.
This integration approach shows how custom development can bridge the gap between established enterprise systems and modern business requirements, enabling operational efficiency without costly infrastructure replacement.

Lokabox now operates with fully integrated telephony and CRM systems where their existing Siemens infrastructure works seamlessly with HubSpot. Sales team productivity increased significantly through automated administrative processes while maintaining their established calling workflows.
