Apache Guacamole vs. Lumen Next-Generation SIP Voice Services

Limitations are only the effort you want to have to configure it (correctly).

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.

• We have experienced some stability problems (mostly Tomcat related).
• The interface could be a little more user-friendly.
• Certain keyboard shortcuts used by Guacamole GUI are impossible to use in the Firefox browser in out-of-the-box configuration.

• 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.

it's easy

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.

It's easy and free of use, therefore perfect for quick implementations when needed.

We have successfully used noVNC for remote access.

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.
