Today we’re enhancing our queuing feature for TeXML by enabling users to add new calls to the queue as part of our Voice API.

Users can use the <Enqueue> command to add the call to an existing queue. The resulting calls will wait on hold until they are dequeued by another caller or removed from the queue via a REST request or the <Leave> verb.

If a queue does not already exist, a queue is created on-demand and can be modified using the [REST API](https://developers.telnyx.com/api/call-control/retrieve-call-queue). You can set up the new feature by [following the guide](https://developers.telnyx.com/docs/voice/programmable-voice/queueing-calls) on our developer site. 

If you have any questions about our Voice API or Telnyx, [reach out](https://telnyx.com/contact-us "Contact Us") to a member of our team of experts.

In order to improve visibility and communication regarding Port Orders, we are adding a new webhook for Port Ins that will notify Telnyx customers when new comments are added to Port Orders that are in progress.

Today, Telnyx is excited to launch Push Notifications for our WebRTC SDK. 

Most users are familiar with Push Notifications- they’re the clickable pop-up messages available across mobile and web applications. Push Notifications allow users to read messages from apps, without having to actually open the application.

Push Notifications come with a number of [inherent benefits](https://telnyx.com/resources/push-notifications-benefits "Push Notifications Benefits") for both developers and end-users. Firstly, they don’t require the application from which they come from to be open on a device to be received by the user. When a Push Notification is sent, the app can ‘wake up’, thereby preserving the battery of the device. They also enhance the security of communications and improve app efficiency by going directly to the given application for processing. 

Telnyx is offering Push Notifications to our users through the WebRTC SDK. You can implement push notifications into your communications apps by [following our latest guide](https://developers.telnyx.com/docs/voice/webrtc/push-notifications "Push Notifications Guides") for both iOS and Android on our Developer site. 

For more information about Push Notifications and our WebRTC offering, [contact a member](https://telnyx.com/contact-us "Contact Us") of our sales team today.


Telnyx's WebRTC SDK now supports Push Notifications. Details in this post.

Telnyx customers can now control and monitor data usage on a per-SIM-card basis and on SIM groups.

The __Data__ section is available for __SIM Cards__ and __SIM Groups__ in the Mission Control Portal. These tools allow data limits to be set and data usage to be monitored for the current month, for individual SIM cards and SIM Groups, respectively. Users can specify limits or allow unlimited usage for SIMs or SIM Groups.

![SIM Data Limits](https://images.ctfassets.net/taysl255dolk/5CGlaxI4ySsmhXpt12ccmS/5560ebf979b9450059c7e36fdd9dae57/sim-data-limits.png)

An email notification will be sent when the usage for a SIM or SIM Group reaches 80% of the prescribed data limit in a given month. When the prescribed data limit is reached by a SIM or SIM Group, the SIM or SIM Group will be automatically disabled.

Get started with SIM Card Data Limits by [logging into your Mission Control Portal](https://portal.telnyx.com/#/app/wireless/sim-groups "Wireless - Telnyx Mission Control Portal").

Learn how to set limits and monitor data usage on Telnyx SIM cards.

At Telnyx we’re always looking for ways to improve our customer experience and make our network more stable and robust. 

As part of these efforts, you can now add allowed IP addresses to your [Mission Control Portal](https://portal.telnyx.com "Mission Control Portal") account. This prevents SIP signals and media IPs originating from your allowed IP addresses from being blocked as part of any actions we take to secure our network.

You can add your allowed IP addresses to your SIP connections in 4 quick steps:

1. Log into the Mission Control Portal and navigate to the __My Account__ section in the upper right-hand corner.
2. Scroll to the __Access Control IPs__ section and click __Add IP__.
3. Enter the IP Address and type you want to allow. 
4. Click __Create__.  

You can also leverage our API through our developer docs.

*NOTE: If you are completing this exercise as part of the DDoS mitigation process, the IP address type does not matter (signaling or media).*

And that’s it! If you have any questions about adding your allowed IP addresses please contact a member of our team using the chat function in the Mission Control Portal - they’re online 24/7/365.

You can now add allowed IP addresses to your Mission Control Portal account.

We are excited to announce that, as of today, Telnyx supports emergency calling with dynamic locations in the US and Canada. 

Before this we offered regular E911, which is non-dynamic emergency calling for numbers. This will continue to be an available option for non-US or Canada numbers.

RAY BAUM’s Act states that, by 2022, enterprises operating Multi-Line Telephone Services (MLTS) will be required to provide dispatchable location information at the time of all 911 calls. Telnyx’s Dynamic E911, also known as E911 with Dynamic Location Routing, can help get you there. Unlike traditional emergency calling where the emergency-enabled phone number is associated with a specific address, Dynamic E911 phone numbers are decoupled from addresses, and instead associated with an end user. In order to utilize Dynamic E911, Telnyx users must now define end users at onboarding. 

Accurate location information of the end user is sent at the time of a 911 call using PIDF-LO (Presence Information Data Format-Location Object). 

To test out the new API, head over to our Developer Guide. If you’d like to know more about our emergency calling capabilities, reach out to our [team of experts](https://telnyx.com/contact-us "Contact Us").

Dynamic e911 provides accurate location information at the time of a 911 call.

From today, Telnyx now supports premium answering machine detection (AMD) on our Voice API. This feature will increase the accuracy of voicemail detection, so your businesses can deliver the right messages, at the right time. 

Premium AMD uses advanced speech recognition technology and a machine learning process to achieve exceptional accuracy in determining whether a call has been connected to a live person or an answering machine. This feature can make more granular classifications of the call result by identifying, silence, an answering machine greeting, a human residence greeting, or a human business greeting, giving businesses a greater understanding of where their calls are ending up. 

When a call is answered, the premium AMD software runs real-time detection and sends a ‘call.machine.premium.detection.ended` webhook with one of the following results: 

- `human_residence`, 
- `human_business`, 
- `machine`, 
- `silence` or 
- `fax_detected`. 

If a beep is detected a `call.machine.premium.greeting.ended` webhook with the result of `beep_detected` is also sent. If a beep is detected before `call.machine.premium.detection.ended` only a `call.machine.premium.greeting.ended` webhook is sent. If a beep is detected after `call.machine.premium.detection.ended`, both webhooks will be sent.

Premium answering machine detection is now available with pricing listed [here](https://telnyx.com/pricing/call-control). Get started with answering machine detection by following the guide in our [developer docs](https://developers.telnyx.com/docs/voice/programmable-voice/answering-machine-detection). 

For more information about how premium AMD can help your business, check out our [product page](https://telnyx.com/products/voice-api) or [get in touch](https://telnyx.com/contact-us "Contact Us") with our team of experts.

Boost your call accuracy with Telnyx's premium Answering Machine Detection. Identify human greetings, machines, and silences for just $0.005/call leg.
