Lumen Next-Gen Voice vs. Telnyx

CenturyLink SIP is an acceptable solution if you have an on-prem PBX (ShoreTel, Mitel, etc) that accepts SIP. I have found a better solution is to run two different carriers through SD-WAN (such as Bigleaf or Velocloud MSR) and use a provider like BCMOne (formerly NexVortex) to manage the SIP.

Telnyx is well suited for general phone number provisioning as they have a large pool to choose from. There is certainly room to grow with fax troubleshooting.

Incentivized

• Reliable service
• Supports wide range of key features
• They do have high levels of support where you can receive real answers

• Price Matters for the flourishing organization like us. Telnyx [is] affordable to us.
• Telnyx is very generous in terms of providing regular updates through webinar , free credits, real time support . One most important is that they are not in hurry of closing the account because of minus balance.
• Telnyx Portal is pretty easy to navigate and manage the customized settings.
• Among other giant SIP providers I found Telnyx with very modern and humble customer approach.

• Lumen-Centurylink has suffered from many noticeable outages in the last few years - this is a blow to their reputation that they still have to recover from.
• Lumen-CenturyLink does not peer well enough with OTHER carriers - they depend on their own network to give you SIP, which means less true redundancy.
• Lumen-CenturyLink needs a better customer portal/interface to handle failover, see the real-time status, etc.

• Number testing: Currently I need to call our fax numbers manually to confirm fax tones. It would be useful to test numbers in bulk from the portal.
• Troubleshooting: Currently, samples are needed for each fax transmission when there are issues. And those samples need to be within 24-48 hours. It would be useful if Telnyx could do a health check out proactively to gather information on high failure counts prior to customer reports.
• Transparency with system issues: We've run into scenarios where we wanted information on system-wide fax failures, but when the issues were resolved we didn't get root cause analysis.

They utilize a private IP network back end that makes SIP configuration for inter-carrier operation difficult because they assume that projecting their private network outside is ok.

SIP service support is definitely improving. A few years ago I would have rated them a 2. Now a 7. But, Lumen still needs a better portal experience to report and see a real-time status. Also to manage SIP failover functions in a WYSIWIG/GUI interface. When Lumen's network breaks in a larger outage, there are long hold times and support is not good.

They are providing services using a Freeswitch system behind a NAT router and they expect carriers to deal with their NAT network. Their support team does not seem to understand that problems caused by exposing a NAT switch to the Internet at large.

CenturyLink [Enterprise Voice SIP] was the incumbent, so switching providers, particularly for our HQ was an overwhelming task for our small team. We did migrate from the legacy CenturyLink voice product EIPT to the new Voice Complete solution as well as upgrade our US and UK circuits along with a hardware upgrade of the managed PE routers in each location. We also decided to implement RingCentral in one of our very small international branches but the lack of features is problematic. We still have T1 service in our other international branches but are looking to go full cloud SaaS PBX there, likely through Microsoft Teams, which we already use for messaging. There are some complexities, as we can't port our numbers directly yet and need to set up an additional CUBE router for SIP. Eventually we hope to get to fully SaaS via Teams.

Easy of use and better prices. Outstanding customer service. Variety of services in telecommunication needs. Easy use of interface even for not experienced users. Migration of SIP numbers is easier. Reporting is very easy to use and customizable for our specific needs, so we can keep track of costs in an easy way

Incentivized

• Faster learning
• Increased numbers of calls
• Organization of calls

• Due to easy SIP truncation the cost of customer approach has become very convenient internationally. We got a so much scaling to play on large customer base. And large base makes sense of large positive ROI.
