[Asterisk-Users] Choppy Ringing

[Todd Weiser]

Found the problem...  We recently upgraded our IOS to 12.4 on our  
1760 cisco router.  This introduced the choppy ringing.  Previously,  
I had mentioned that this issue didn't occur when using ulaw.  I was  
incorrect.  This bug effected both g729 and g711ulaw codecs.  After  
checking the cisco ios bugtracker, 12.4(3) has a lot of voice bugs  
that affected us.  Rolled the router back to c1700-ipvoice-mz. 
123-12e.bin and all is well.
