🔹Project Level Settings at Your Command!
Within each project you can now turn on or off the following settings, giving you more control when you have multiple projects running.
Protect media URLs for fax, recording, and messaging — when enabled, direct URLs must be authenticated to access.
Force HTTPS requests — for optional added security, prevent HTTP URLs from being saved for usage. When enabled, HTTP URLs will be converted automatically to HTTPS URLs.
🔹Don’t Let Guest Tokens Clutter Your Space.
Under the "Subscriber" sub-tab (within My Resources), guest tokens specific to temporary subscriber access will no longer be visible. These guest tokens will also not show within the API. Learn More about Guest Tokens
🔹Want to experiment with our APIs?
Download the collections, change the authentication variables to their own, and begin using our APIs right away with no downtime or setup time. The SignalWire Postman/Bruno API collections have been updated to include:

We’re excited to announce the release of the SignalWire Agents SDK—a Python-native toolkit that makes it faster and easier to build real-time AI voice agents with built-in support for SIP, PSTN, WebRTC, and messaging.No more piecing together APIs or handling telecom complexity. With the Agents SDK, you can:
Build AI agents using familiar Python tools
Run AI Agents as microservices, Lambdas, or CGI scripts—your choice
Add skills like search, knowledge lookups, or custom tool calls with one line of code
Deploy production-ready agents with ultra-low latency (~500ms globally)
Use tools built for Model Context Protocol (MCP), an emerging standard for defining AI tool interfaces, without rewriting them.
Whether starting from scratch or scaling a mature voice AI application, the Agents SDK lets you focus on building great conversations, not wiring up infrastructure. No SIP expertise required, just bring your Python skills.

Tired of watching your long SMS messages get split into weird chunks? We are too. That’s why SignalWire now supports sending long text messages as a single MMS — no more guessing where your message will get cut off.
When set to true, this parameter forces the message to be sent as an MMS, even if the message body contains only text.
cXML: use the SendAsMms parameter
RELAY: use the send_as_mms parameter
📚 Docs: https://developer.signalwire.com/rest/compatibility-api/endpoints/create-message/
Reduce friction and gain better control over your message formatting by delivering long messages as a single MMS payload. Just another reason why SignalWire's programmable communications platform is better than duct-taping features together.
