What is Fonoster?
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
What is Quo?
Quo plugs into Claude as a callable business-comms tool while transcripts become first-class data.
Quo's recent shipping is two-pronged. The headline move is an official Claude connector that turns the product into an action surface for AI — summarizing calls, sending texts, looking up and editing contacts. Around it, the team is treating call transcripts as searchable, exportable data and tightening the HubSpot integration so contact edits flow both ways.

Fonoster
7.5COMMS
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
◆ Current state
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
◆ Where it's heading
After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
◆ Prediction
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
Quo
6.3COMMS
Quo plugs into Claude as a callable business-comms tool while transcripts become first-class data.
◆ Current state
Quo's recent shipping is two-pronged. The headline move is an official Claude connector that turns the product into an action surface for AI — summarizing calls, sending texts, looking up and editing contacts. Around it, the team is treating call transcripts as searchable, exportable data and tightening the HubSpot integration so contact edits flow both ways.
◆ Where it's heading
Quo is positioning itself as the business-phone surface that AI assistants reach into. The Claude connector gives Quo distribution inside an AI client; transcript search and markdown exports make Quo conversations queryable by humans and agents alike; the HubSpot two-way edit removes the last 'open another tab' moment in a sales call. The trajectory points to AI-native customer-conversation workflows, not just calling and texting.
◆ Prediction
Expect more agent connectors (ChatGPT, custom MCP) and more agent-callable verbs (initiate calls, draft follow-ups, push transcripts into pipelines). Watch for deeper CRM-write integrations beyond HubSpot — Pipedrive, Salesforce — to keep parity as the agent surface grows.
