[asterisk-biz] Locally vs Server generated ring tones

[Mark]

Paul,

In most cases the calls are being answered immediately by an IVR, so 
those are not a concern.

In some cases however the calls are not going to IVRs and the recipients 
phone/ATA will ring while the caller hears nothing. The caller continues 
hearing nothing untill the call is answered. Asterisk is not answering 
the call, the call is not being completed till it is picked up. I am 
pretty sure that Zafer hit the nail on the head. Some systems requre the 
ringback to be generated by the endpoint or a server further on down the 
line. I will see if I can work wioth this on Monday.

For those of you wondering, what this means is that you can actually 
play media BEFORE the call is answered.
