We are doing a new install and the customer has Vodafone ISDN 30 x 3. These are running on the Avaya ACM. When we put them on to the new IPO server edition we can't make out going calls. Incoming is ok. They also have one site with BT ISDN 30 when we put this on the system it works. Has anyone else had a problem with Vodafone? and if so what was the fix?
