atcomsystems.ca/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems Partner ACS Release 8 and Vonage VOIP as CO Lines

I also have a Partner ACS System that wants to change phone vendor. Their Partner ACS is a release 3 and they want to switch to a local Cable company. Do you think there will be a problem with the software release being so old? And will their need to be some sort of analog adapter for this as well? Any help would be greatly appreciated!!! Thanks
