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

[Connor Spiess]

Mark,

We have also seen this in our lab environment and switched to 5ess and it has gone away. In places we've seen similar problems with NI2 we have had to spend a lot of time on the phone with the telco, unfortunately they never will tell exactly what they changed on their end. I will see what I can do to get you more info.

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?

Mark
