[Asterisk-Users] Double Call Progress tones

[kevin ling]

Hi,

I have the same problem on TE110P and Taiwan telco PRI line. I think to fine
tune the rigntone frequencies not resolve this problem. 

For example.
When I make a call to mobile. I can hear one ringtone like geneate by
asterisk or device. And another ringtone like from telco. You known, some
mobile will pickup the call and play music before user really answer the
call. So I can hear music and mix with ringtone. 

Regards,
kevin

Configure the ringing frequencies on the sip devices so that is something
not udible by human hears (we did that as a quick fix before discovering
progressinband some time ago, worked for linksys pap)
