New Quality of Service (QoS) Reports for Voice Calls Now Available in Mission Control
At Telnyx, we know that it’s important for our customers to be able to track all aspects of their calls. Today, we’re excited to release Quality of Service (QoS) reports for voice calls to help users troubleshoot call quality issues that may arise.
This new feature will give customers a visual representation of the Quality of Service (QoS) of any given call on a timeline with two separate graphics, one for each the RTP media streams that are established for each call.
On these graphics customers will be able to see 4 different metrics:
- Packets “Packets” represents the incremental number of RTP (real-time transport protocol) packets that were sent in this direction.
- Packets lost “Packets_lost” represents the incremental (accumulated) number of RTP packets perceived as lost by the RTCP (real-time transport control protocol) information, as measured by the receiving party.
- MOS “MOS” (Mean Opinion Score) represents the value as a function of Jitter, the number of lost packets, and the round trip time (RTT)- when available- as measured by the receiving party.
- IA Jitter “Ia_jitter” represents the value of Interarrival Jitter, as measured by the receiving party.
The QoS report will enable users to quickly identify any issues that might have affected the quality of the call, which will speed up the troubleshooting process. Take a look at the sample report below:
Sample QoS report now available in Mission Control
The new report feature is available in the Mission Control Portal through the Advanced View of our SIP Debugging tool.

New Advanced SIP Debugging Feature Now Available in Mission Control
Telnyx are delighted to announce the launch of an advanced SIP debugging feature in the Mission Control Portal.
Behind the scenes, Telnyx engineers have been using the Homer tool to troubleshoot issues with SIP calls. We have integrated the Homer tool to extend it’s use to Telnyx customers for easy troubleshooting through an improved UI and a host of new features. Telnyx portal users now have the ability to:
- export the callflows in PCAP format for advanced packet inspection
- export the callflows in text format for sharing.
The Advanced SIP debugging tool will allow Telnyx customers to perform an in-depth inspection of their SIP calls.
Telnyx plans on adding QoS metrics to the advanced SIP debugging tool to enable our customers to measure audio quality of calls on a timeline report.
Telnyx users can access this new feature by navigating to the ‘Debugging’ tab on the menu on the left hand side of your Mission Control Portal and clicking ‘Advanced View’. Why not check it out?

Changes to Outbound Voice Profiles
We’re launching a new Outbound Voice Profile creation experience in the Mission Control Portal to simplify the process of getting up and running with your Telnyx account.
Why We Changed Outbound Voice Profiles
As we continue to expand our international SIP trunking services across the globe, we’ve heard a lot more feedback from users who want a simple process for seeing international outbound call pricing and making international outbound calls with Telnyx. With that feedback in mind, we’re confident that this new experience will make it easier than ever for customers to start making outbound calls on our global, purpose-built communications network, and see exactly how much those calls will cost.
Simplified Traffic Types
Users now only need to specify whether their voice traffic type is Conversational or High Volume/Short Duration.
Our telephony engine now handles fax traffic and direct routing as standard, so there’s no longer any need to select the Fax or Conversational Direct traffic types to enjoy these benefits.
US and International Calling, all in one Conversational Outbound Voice Profile
Users who create a new Outbound Voice Profile and select the Conversational Traffic Type for regular calls can use this profile to make calls internationally.
There is no longer any need to specify a Service Plan on Outbound Voice Profiles, or to create separate profiles for USA-48/CAN and International Service Plans. You can still choose to allow or disallow calls by international destination, set maximum allowable destination rates, and set daily spend limits on connections to protect your account from fraud.
Pricing for US and international outbound calling is now available in one Global Conversational rate deck. Users can find this deck under “Outbound (Termination) Voice/Fax Usage” in the Voice Pricing section of the Mission Control Portal.
Legacy Outbound Voice Profiles
If you created an Outbound Voice Profile before today, you’ll still be able to edit its settings with the Legacy Outbound Voice Profile experience. For any profiles created after today, you’ll see the new experience as described in these release notes.
For a limited time, creating, updating, and adding connections to Legacy Outbound Voice profiles will still be supported.
The following functionality of Legacy Outbound Voice profiles will be removed when support for legacy profiles ends:
- Switching back to the legacy experience when creating new Outbound Voice Profiles in the Mission Control Portal, to specify legacy traffic types (like Fax and Conversational Direct) and service plans.
- Creating Legacy Outbound Voice Profiles via the Telnyx API.
- Adding connections and apps to a Legacy Outbound Voice Profile.
For more information on Outbound Voice Profiles, talk to our experts.

International Conversational Direct
We’re excited to announce a new product for international outbound voice — International Conversational Direct, which is now available in the Mission Control Portal and the Telnyx API.
International Conversational Direct offers improved quality and higher connection rates on your outbound calls. Call quality is enhanced by optimizing the route preferences and leveraging our direct partnerships with local Tier-1 carriers across the globe to choose a high-quality route every time.
Set up high-quality global outbound calling in minutes with the Mission Control Portal for more direct call connections and better quality. You can enable International Conversational Direct in two simple steps:
- Create a new Outbound Profile with Traffic Type: Conversational Direct and Service Plan: International + US-48/CAN
- Assign a connection to your new Outbound Profile.
Usage-based pricing for International Conversational Direct termination can be found by logging into your Mission Control Portal and heading to the Pricing page.
This launch builds on our existing high-quality termination offering, including our domestic Conversational Direct product launched late last year.
Want to configure your Outbound Profiles to enable International Conversational Direct via API instead? Head on over to our Developer Center to learn how.

Emergency Services In Ireland
We’re excited to announce the addition of emergency services to our numbers in Ireland. Emergency services can be enabled on some local Irish numbers for an additional monthly recurring cost.
How do I enable emergency services on my Irish numbers?
Emergency services can be enabled on your local numbers in just a few steps via the Mission Control Portal:
- Purchase an Irish number
- Select the ambulance icon 🚑 next to your number in the My Numbers section of the Mission Control Portal.
- Enter or select an address in the dialog box. This address is provided to the emergency services when an emergency call is made from your number.
Please note that addresses must be entered in the correct format, including the Business Name, Street Address, Extended Address, City/Locality and Postcode fields populated, and with the State field containing the name of a county in the Republic of Ireland:
Carlow, Cavan, Clare, Cork, Donegal, Dublin, Galway, Kerry, Kildare, Kilkenny, Laois, Leitrim, Limerick, Longford, Louth, Mayo, Meath, Monaghan, Offaly, Roscommon, Sligo, Tipperary, Waterford, Westmeath, Wexford, and Wicklow

Global Expansion for SIP Registration
We’re excited to announce that we’ve expanded support for SIP registrations to even more global destinations. With this release, we now support registrations locally within Europe and Australia, with Canada coming soon.
This global expansion enables registrations beyond our US sites located at sip.telnyx.com. SIP registrations are now possible on the following domains:
- sip.telnyx.ca (coming soon)
This means that customers using devices which depend on SIP registrations can now register with any of the regions listed above and be able to receive inbound calls from the regional SIP proxy.
We’ve also extended our full support for UDP, TCP and TLS to each of these new locations, so you can keep using your existing signaling protocol. With regional routing of your SIP signaling traffic, you’ll experience reduced latency and improved deliverability.
Configuring your SIP Region is easy and can be tested with the following steps:
- Register your SIP device against sip.telnyx.XXXX
- Make a phone call to the number or SIP URI assigned to the Connection.
- Your SIP device will receive the inbound call from the SIP regional proxy that you registered against.
That’s it — you’ve now updated your SIP Registration region. To find out how you can complete these same steps via API, check out our Developer Center.
For more information on SIP Registration, head over to sip.telnyx.com.

New Telnyx PoP in Sydney, Australia
The release of a new Telnyx point-of-presence (PoP) in Sydney, Australia brings about three big changes to the Telnyx network.
The first is our continued global network expansion. The rollout of our first point-of-presence in Australia — with more to come in the near future — expands our connection points to the Telnyx network, to benefit customers in Australia and Asia.
Secondly, we built Anchorsite® to improve call quality and reduce packet loss, with traffic routed through the PoP with the lowest latency. You can now choose to anchor your call media at this new Sydney PoP for even better call quality.
And finally, SIP signaling is now possible through this new region. You can test this out by pointing your SIP devices to sip.telnyx.com.au for outbound calls, or by selecting Australia as your SIP region under Connections Inbound settings for inbound calls.
It’s now possible to keep both your call media and signaling all within Australia, reducing latency and directing all media and traffic over our private IP-network.
If you’re interested in anchoring call media and SIP signaling at this new location, you can configure your connection in the Mission Control Portal. Check out our Developer Center to see how you can make the same updates via the Telnyx API.
