No, phone on LAN, through Asterisk box on LAN, through firewall, out to fiber connection (lots of capacity there), to ITSP.
 
Codec is uLaw.
 
This only happens sometimes, so I'm wondering if it's an asterisk bug? Aastra bug?  Network latency?  LAN capacity, etc.  Never seen this before...

What codecs are you using? Are the calls internal(local network) only?

We have inherited an installation with Ast 1.4 and Aastra phones.  The client complains that sometimes the call audio turns tinny and robotic...I heard it and it sounds wierd.
 
Has anyone else experienced this?  Cause?  Solutions?
 
Thanks,
