Change or Increase the Length of Dial Tone
I have the Cisco SPA3102 and when attempting to setup a conference I found the default 10 second dial tone duration was not long enough - the fast busy would kick in before I finished searching through the phone directory.
To change the duration follow the below instructions:
- Login into the VOIP box
- Select 'Advanced' mode
- Select 'Voice' tab
- Select 'Regional' sub tab
- Under 'Call Progress Tones' modify the 'Dial Tone' default entry's 10 second delay to whatever duration you wish.
