INFO: FOIP Standard Edition does not distinguish voice calls Print ZTN1811 ID: ZTN1811 This Zetafax technical note applies to: Zetafax Version 2010 Summary The FOIP Standard Edition device controllers do not recognise voice calls. All voice calls will be treated as a ‘no answer’ or ‘unable to connect’ and be placed into the server retry queue. More information The ‘Retry if voice answered’ option is ineffective when using a FOIP device. Voice calls are recognised as an unanswered or unconnected call and behave as such, with retries occurring at the set retry intervals. Last updated: 6th August 2010 (NT/MW)
