What is Fonoster?

Fonoster 0.22.x fixes audio playback lifecycle and process crash on hangup

Two back-to-back patches address audio SDK correctness: v0.22.13 fixes playStream to resolve only after playback completes (previously it could resolve prematurely), and v0.22.14 catches unhandled promise rejections on call hangup that would crash the Node.js process. Both touch the call/audio lifecycle, which is the core of Fonoster's programmable voice SDK.

What is Salesmsg?

Salesmsg deepens HubSpot automation while AI agents gain autonomous action across text and calling

Salesmsg has been adding AI agent capabilities at a high cadence across both text and calling channels. The calling AI agent now accepts inline action commands via slash syntax in prompts, logs post-call notes, and tags contacts by detected intent. The texting agent handles opt-outs autonomously and escalates to humans with full context. Both channels feed into HubSpot and Salesforce with broad record-level coverage—messaging from Deals, Tickets, Companies, Orders, and Carts—and automatic activity logging.

Fonoster vs Salesmsg: editorial side-by-side

F5.0

Fonoster 0.22.x fixes audio playback lifecycle and process crash on hangup

◆ Current state

Two back-to-back patches address audio SDK correctness: v0.22.13 fixes playStream to resolve only after playback completes (previously it could resolve prematurely), and v0.22.14 catches unhandled promise rejections on call hangup that would crash the Node.js process. Both touch the call/audio lifecycle, which is the core of Fonoster's programmable voice SDK.

◆ Where it's heading

Fonoster is in active maintenance of the 0.22.x line, addressing stability issues in the audio primitives. The fixes are focused correctness patches — no new feature surface visible in these entries.

◆ Prediction

A feature release for 0.23.0 is likely once this patch cycle settles; the narrow scope of recent fixes suggests the core SDK is maturing.

S5.0

Salesmsg deepens HubSpot automation while AI agents gain autonomous action across text and calling

◆ Current state

Salesmsg has been adding AI agent capabilities at a high cadence across both text and calling channels. The calling AI agent now accepts inline action commands via slash syntax in prompts, logs post-call notes, and tags contacts by detected intent. The texting agent handles opt-outs autonomously and escalates to humans with full context. Both channels feed into HubSpot and Salesforce with broad record-level coverage—messaging from Deals, Tickets, Companies, Orders, and Carts—and automatic activity logging.

◆ Where it's heading

Salesmsg is building toward an AI-first communication layer that handles the full inbound/outbound cycle—from QR-code tap to booked meeting to NPS survey—without requiring human intervention on routine interactions. The pattern of features (action injection, intent-based routing, cross-record messaging, automated handoff summaries) is consistent: each release reduces the cases where a human must step in. CRM depth across HubSpot and Salesforce means the sales workflow can stay inside Salesmsg with less custom glue code.

◆ Prediction

The most likely next move is expanding the AI agent action library—more CRM write-back triggers, additional integration targets, or deeper calling agent decision trees. Given the pace of HubSpot-specific features, a formal HubSpot Marketplace listing or certification is a plausible growth lever.
