thank you for your help.  if you define 1400+2060+2450+2600/100,0/100 as a 
tone in indications.conf, then set up a test extension to play that tone, are 
you able to hear the same tone generated by the attached mp3 file?  i have 
not been able to replicate that tone (that i got from 
http://www.3amsystems.com/wireline/tone-search.htm?start=20&kCountry=184&format=Zaptel )

i can play all the other default tones in indications.conf properly.

a quote from indications.conf:
; The frequency component may be a mixture of two
; frequencies (f1+f2) or a frequency modulated by another frequency (f1*f2).

my only guess as to why the tone i'm trying to create won't work is because 
the first part is a mixture of 4 tones (1400+2060+2450+2600) and maybe 
asterisk won't generate that, though i'm not sure.
