Multi-Channel Analytics Dashboard: CallSphere vs Vapi Single-Channel
CallSphere's dashboard scores sentiment, lead, intent, and satisfaction across voice, chat, SMS in one view. Vapi shows voice metrics only.
TL;DR
CallSphere's analytics dashboard scores sentiment, lead quality, intent, satisfaction, and escalation likelihood across every channel — voice, chat, SMS, email — in a single view. Vapi shows voice-only analytics. For multi-channel operations, that gap means either incomplete pictures or expensive BI integration to assemble what CallSphere ships by default.
What Multi-Channel Analytics Actually Means
Most "multi-channel analytics" claims fall apart on inspection because the underlying metrics are inconsistent. Voice sentiment from one vendor uses a 1-5 scale, chat sentiment from another uses -1 to 1, SMS sentiment from a third doesn't exist at all. Stitching these in BI is possible but rarely produces comparable scores.
CallSphere computes all enrichment with the same model, the same prompt, and the same scale across every channel. A sentiment score of 0.7 means the same thing whether the conversation was voice, chat, SMS, or email. That comparability is the foundation of useful multi-channel analytics.
The Five Enrichments
Every conversation in CallSphere gets five scores:
| Metric | Scale | Meaning |
|---|---|---|
| Sentiment | -1 to 1 | Tone of customer expressions |
| Lead score | 0-100 | Likelihood of conversion |
| Intent | text | Classified purpose (booking, support, complaint, etc.) |
| Satisfaction | 1-5 | Inferred customer satisfaction |
| Escalation | bool | Did the conversation escalate to human |
These are computed by an enrichment service that runs against the transcript after every conversation closes. The prompts are tuned per vertical (healthcare, salon, sales) to capture domain-specific signals.
The Dashboard Views
The CallSphere admin dashboard ships with these multi-channel views:
- Channel mix over time — Stacked area chart of voice vs chat vs SMS volume
- Sentiment trend by channel — Line chart, one series per channel
- Lead score distribution — Histogram filterable by channel
- Intent funnel — Conversion from "browsing intent" through "booking intent" to "completed booking" across channels
- Escalation hotspots — Which channels and which intents cause the most human escalations
Operators can filter by tenant, date range, customer segment, or agent.
Vapi's Analytics Gap
Vapi exposes voice analytics through its API and dashboard: call volume, average call duration, call disposition, and (with extensions) transcript-derived insights. None of this includes chat, SMS, or email — because Vapi doesn't operate those channels.
A Vapi customer with multi-channel needs typically:
- Sets up a data warehouse
- Pipes Vapi voice data, chat platform data, and SMS data into it
- Builds Looker/Metabase dashboards stitching the sources together
- Maintains the dashboard as schemas drift
That is months of data engineering and an ongoing maintenance commitment.

The diagram emphasizes the symmetry: every channel's transcript flows through the same enrichment, producing comparable scores in a single store consumed by a single dashboard.
Real Example: A Sales Team's Quarterly Review
A B2B SaaS sales team running CallSphere across voice, chat, and SMS does a quarterly review. Their findings:
- Chat lead-score average is 12 points higher than voice lead-score (chat prospects are further along the buying journey).
- SMS sentiment dips sharply on Friday afternoons (reschedule requests for Monday demos).
- Intent classification shows that 18% of voice calls are actually billing questions misrouted from chat (action: improve chat self-serve for billing).
- Escalation hotspot is "voice + intent=technical-question" — they hire a technical SE to handle these.
These four insights came from one dashboard in one afternoon. On a Vapi-plus-other-vendor stack, each insight would be a multi-week BI project.
Why Comparable Sentiment Is Strategic
Sentiment is only useful when comparable. CallSphere's single-model approach makes "compare voice sentiment to chat sentiment for the same customer" a one-line query. Once that comparison is possible, the insights cascade:
- Customers whose chat sentiment is positive but voice sentiment is negative often have phone-anxiety; route them to chat by default.
- Customers whose voice sentiment is positive but chat sentiment is negative often type poorly; route to voice.
- A drop in sentiment in one channel that is mirrored in another is a churn warning; a drop in only one channel is often a channel-specific UX issue.
These segmentation strategies are impossible without cross-channel comparable sentiment.
When Vapi's Analytics Are Sufficient
If you only run voice, Vapi's analytics are sufficient. The moment you add a second channel, the analytics gap becomes a strategic blind spot.

FAQ
Does the dashboard support custom metrics?
Yes. Custom enrichment prompts can produce additional scores stored in the same call_logs schema.
Can I export to my own BI tool?
Yes. Native exports for Snowflake, BigQuery, and Redshift are included.
Are the sentiment models customizable?
Yes per tenant. Default models are tuned for general use; vertical-specific tunings ship for healthcare, salon, and sales.
Is there an API for analytics?
Yes. The dashboard API is documented and supports the same queries the UI uses.
Does this support RBAC?
Yes. Roles include admin, manager, sales_rep, agent, and requester. Each role sees an appropriately scoped subset of data.
How fresh is the data?
Enrichment typically completes within 30 seconds of conversation close. The dashboard reflects new data within a minute.
