5.7 KX-TA Series PBX Programming for InbandIntegrationNote• The KX-TA824 can also be programmed via PC using the Operating and Maintenance Tool. Refer to5.4 KX-TA824 PBX Programming for Inband Integration for more information.• For KX-TA1232 programming, refer to 5.5 KX-TD Series PBX Programming for Inband Integration.APT Integration is recommended when using the VPS with a KX-TA series PBX, however, Inband Integrationis necessary when:• the PBX has available SLT ports but no available APT ports.• the software version of the KX-TA series PBX does not support APT Integration.Note• If the PBX is programmed to use 2-digit extension numbers, DTMF Integration is not possible. Programthe PBX to use 3-digit extension numbers using System Program [009].1. Enable System Program [102] for each extension connected to the VPS.This parameter is used to tell the PBX which extensions are connected to the VPS. Ports with this parameterenabled can receive Follow-on ID and DTMF Signaling (busy, answered, disconnect, etc.) if the Voice MailIntegration and DTMF (Inband) Integration features are also enabled.2. Enable System Program [103] to turn on DTMF Integration. On extensions with the Voice Mail portparameter enabled, the PBX can send DTMF signals to indicate call status; this increases VPS efficiency.Codes apply to all transferred calls; trunk (CO line) calls only indicate a disconnection (provided the PBXis programmed for CPC Detection, and the Telephone Company sends the CPC signal). Refer to theSequence Codes in 5.2.3 PBX Parameters.3. Put all extensions connected to the VPS into the same extension group using System Program [600].Reserve this extension group for these extensions! Do not mix other extensions into this group.4. Enable hunting for the VPS extension groups using System Program [100].5. Set the hunting type for the VPS extension groups to Circular using System Program [101].6. At every VPS extension, temporarily connect an SLT or test set, go off-hook and dial 7301# to turn on DataLine Security. This prevents the PBX from sending Executive Override or Call Waiting tones to thoseextensions. We recommend that all Voice Mail port extensions have this feature enabled to avoidinterruption during recording.7. Select the appropriate trunk (CO line) feature settings depending on how your customer plans to use theVPS: a) to answer all incoming calls, b) as an operator backup, or c) to only answer calls not answered byuser extensions.8. Program the appropriate trunk (CO line) feature settings depending on how your customer plans to usethe VPS: a) to answer all incoming calls, b) as an operator backup, or c) to only answer calls not answeredby user extensions.a. If the VPS is answering all incoming calls:Trunk Mode—Use System Programs [414] (Day Mode), [415] (Night Mode), [416] (Lunch Mode) toset each trunk (CO line) to DIL mode, and assign the first extension of the Voice Mail hunt group asthe destination for calls received on each trunk (CO line). The PBX will allow incoming trunk (CO line)calls to hunt only if the trunks (CO lines) are DIL to the first port of the hunt group. Lines programmedas Normal do not hunt.b. If the VPS is only answering calls not answered by the operator (Operator Backup):Flexible Ringing Assignment—For each trunk (CO line), use System Programs [408] (Day Mode),[409] (Night Mode), and [410] (Lunch Mode) to enable ringing at the operator’s extension (jack).Delayed Ringing Assignment—To give the operator time to answer the call before the VPS picks up,we recommend setting the delay to a few seconds for each extension connected to the VPS. Set adifferent delay time for each extension connected to the VPS. Use System Programs [411] (Day Mode),[412] (Night Mode), and [413] (Lunch Mode).160 Installation Manual Document Version 3.0 2010/065.7 KX-TA Series PBX Programming for Inband Integration
