Common Issues:

Residential Internet Service Provider Performance Issues

With more people than ever working from and keeping the family home to help stem the propagation of COVID-19, residential Internet service providers are being overloaded.  If your Internet connection feels slow, one possible reason is that your Internet connection can’t hold up to your whole family getting online at the same time. It might also be because of outdated home routers and modems.  If you are using wireless in your home, it may be interference or low signal strength.  Past your home, residential service providers tend to have entire neighborhoods share a single link back to the carrier router.  This can also be overloaded.

Symptoms of home and residential performance issues:

  • “Cannot Connect to Server” errors.
  • One-way Audio
  • Choppy Audio
  • Call Drops
  • A Ring, then a busy signal

Call-ID Issues:

Your Jabber account matches your desk phone’s Caller ID since it is the same. However, if you are experiencing issues where callers are stating they see something else, please verify if they have your contact information saved to their contacts as something else. A caller’s contact settings will affect what they see on their phone. For example, if a relative has your work number saved in their contacts under “Aunt Jane”, they will see that instead.

Not receiving any voicemails (including email notifications):

Please verify if your number is call forwarding. If you have call forwarding enabled, it will bypass your HCC voicemail and go to the forwarded numbers instead.

Unable to make outbound calls or forward calls

Cisco Jabber works the same as your desk phone at work.

  • To make an internal call, simply dial the four-digit extension.
  • To make a local call in the 813 area code, you must dial 9 first and then the 7-digit telephone number.
  • To make a call to any number outside of the 813 area code, dial 91 and the 10-digit telephone number.

Also, when entering the phone number for call forwarding, enter the number as a long-distance number as 91[10-digit number].  For example, 918135551212.
Please do not perform a test call from the number you are call forwarding to.  It will not work.
