After adding the 'x' the softphone still will not register

[previous softphone ver. 1.1 only]

There is a known-issue with the Fonality Softphone where adding the 'x' to the registrar server string does not allow the Softphone to be used remotely.  The following work-around has been qualified and approved by Fonality Tech Support:

  1. Launch the Fonality Softphone
  2. Right-click on the Softphone and select Settings
  3. Select the Server option underneath SIP Accounts (see the image below)
  4. Check the Manual Override option underneath Domain Proxy (please be careful - there are two identical options that say "Manual Override" in this section)
  5. Fill in in the text box next to the word Host (note: you do not need to use the 'x' in this case)
  6. Click Apply
  7. Now UNCHECK the Manual Override option (you are UNDOING everything you just accomplished)
  8. Click Apply
  9. Click Close
  10. The Softphone should register with your server. 


The work-around documented here need only be performed the first time you attempt to use the Softphone from a location remote to your server.  Once you have completed these steps once, the Softphone can be taken to your office and then taken back out to a remote location and register correctly (you must keep in mind that the x in the registrar string needs to be removed when you are local, and added when you are remote each and every time).

So first, make sure that there is a dash roughly in the middle.  For example, here's a made-up license key:

2.) Make sure that the key is copied in with no spaces at the beginning nor end.  Erase any spaces.

3.) Compare the first four and last four characters against the document - it could be that a letter or number is missing at the beginning or end.
