Is it a standard msi install?  If so use the command

msiexec.exe /x {package code} /qn

or can actually point to the origional msi

msiexec.exe /x telestaff.msi /qn

I found this Appdeploy remnant on the subject:

http://216.115.86.222/packages/detail_pf.asp?id=943

it looks like an MSI-based installer

Grab the uninstall command from the software inventory list and make a managed deployment to uninstall it. Not sure if the registry keys are the same but this is the command I used to uninstall our Telestaff 2.61

MsiExec.exe /I{7C9AA089-50BB-48E5-8406-32A1CF44EE76}
