[Asterisk-Users] Sprint PCS -> Asterisk through Digium TDM400P

[Ben Wern]

Unfortunatly, I can't offer any suggestions to correct the issue, but I can 
add that I see this on my X100P as well. It does seem particularly bad with 
Sprint; I think they may have shorter tone lengths than we really need. 

The only thing that I've found so far is that my calls coming in via SIP and 
IAX do not exhibit the problem, so I've transitioned the bulk of my incoming 
traffic to those mechanisms -- may not be an option for you of course.
