What's New¶

CallSystem Provider Registry¶

Register and retrieve telephony providers at runtime:

import (
    "github.com/plexusone/omnivoice"
    _ "github.com/plexusone/omnivoice/providers/all"
)

// Get Twilio provider
twilio, _ := omnivoice.GetCallSystemProvider("twilio",
    omnivoice.WithAccountSID(os.Getenv("TWILIO_ACCOUNT_SID")),
    omnivoice.WithAuthToken(os.Getenv("TWILIO_AUTH_TOKEN")),
    omnivoice.WithPhoneNumber("+15551234567"),
)

// Get Telnyx provider
telnyx, _ := omnivoice.GetCallSystemProvider("telnyx",
    omnivoice.WithAPIKey(os.Getenv("TELNYX_API_KEY")),
    omnivoice.WithPhoneNumber("+15551234567"),
)

// List available providers
providers := omnivoice.ListCallSystemProviders()
// ["twilio", "telnyx"]

CallSystemClient with Failover¶

Manage multiple providers with automatic failover:

// Create client with multiple providers
client := omnivoice.NewCallSystemClient(twilioProvider, telnyxProvider)
client.SetPrimary("twilio")
client.SetFallbacks("telnyx")

// MakeCall automatically fails over on error
call, err := client.MakeCall(ctx, "+15559876543")

Upgrade Notes¶

This is a backward-compatible release. No breaking changes from v0.6.0.

Migration¶

If you were using CallSystem providers directly:

// Before: Direct import
import "github.com/plexusone/omnivoice-twilio/callsystem"
provider, _ := callsystem.New(cfg)

// After: Use registry
import (
    "github.com/plexusone/omnivoice"
    _ "github.com/plexusone/omnivoice/providers/all"
)
provider, _ := omnivoice.GetCallSystemProvider("twilio", opts...)

Both approaches continue to work. The registry pattern is recommended for new code.
