[asterisk-users] Dropped Call Problem -- Looking for ideas and a consultant.

[Mark Engelhardt]

Steve,

Thanks for your thoughts. I am tearing out my last bit of hair on this  
one.

We only use sip on our internal network to talk to the 7960s

We are getting drops from no-cell phone hard wired phones too.

Unfortunately There are too many drops for me to let this go. :(
