Credit Card Machines call fail

[Virtualman9000]

I have two 3300MXe's. One is a trunking gateway and the other is running all the IP phones plus an old 2000 per node with ONS for faxes and credit card machines. I upgraded to the latest v9 from v8 last night. No programming changes. Customers credit card machines are now failing on most calls out. No compression on the IP trunks between the two PBXs. Has something changed between v8 and v9 to cause this?

Thanks

I'm unaware of any changes like that but...
I've seen some class of service options get changed/deleted during an upgrade.
Check the COS of the analog stations for trunk access and the like. Make sure the COS is set the way it was before the upgrade.

You can't believe anything you read... unless of course it's this sentence.

v9 had a change to support t.38 which may have caused you grief. Officially, I don't think modems are supported, but I believe there are ways of undoing the changes if you aren't using T.38.

I've decided to move the per node with the analogs to the trunking gateway so I don't have to worry about IP trunks. I realize I should have done it like that 2 yrs ago when I installed it. Oh well, live and learn.

No modems should connect over IP trunks as it is extremely unreliable regardless of what others say.
