[cisco-voip] Rings sound odd

[Erick Bergquist]

The first 2 rings or so are ring back before the gateway/router answers the call while router is waiting a ring or so for caller id info to be collected (from carrier/telco). After that call is passed through to CCM/CME/whatever and that may be modifying the progress indicators, tones, etc and thats why you hear a difference. I don't know the specific details on this part of the puzzle but I'm sure someone else will chime in. 

What does the call connect to, and how are the dial-peers and voice port configured?

Hello.  2801 in H323 mode.  12 POTS lines plugging into FXOs.  Caller ID.

When I call one of the POTS lines, the first ring sounds fine.  The beginning of the 2nd ring sounds fine, but the 2nd half of the 2nd ring changes sound considerably.  Why is this?  (The 2nd half of the 2nd ring, and 3rd ring after that, sound much less "quality" than the first  1.5 rings.)  Do I need to change a setting somewhere??

Thanks!
