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

[Mark Engelhardt]

Conner,

I contacted my telco and they report they have a:

"EWSD Siemens Central Office"

Which does not support 5ess

Any other way around this? How did you determine changing to 5ess  
would fix your problem?
