Connect agreed office extensions across branches using a supported PBX and network design. Dial plans, authorised routes, connectivity and outage behaviour are confirmed; inter-branch calls and public telephone service have different dependencies.
Conceptual Multi-Branch Telephone product and system illustration for Telephony. Final device form, model, interfaces and quantities are confirmed from the assessed scope and approved product data. Conceptual source-to-audience signal path for Multi-Branch Telephone, derived from this page's scope, interfaces and acceptance record.

It sits in IP Telephone / Communication under Telephony. The final deliverable is shaped by the intended outcome, the installed or proposed environment and the interfaces that must be owned, supplied, integrated and tested.
Connect agreed office extensions across branches using a supported PBX and network design. Dial plans, authorised routes, connectivity and outage behaviour are confirmed; inter-branch calls and public telephone service have different dependencies. List branches and extensions, PBX ownership, inter-site connection, permitted dial routes, numbering, codec compatibility, public trunk responsibility and behaviour when a branch link fails.
From the initial brief to the handover record: what to prepare, check and confirm with HJ.
Define Telephony as the operating result for Multi-Branch Telephone, including the users, process and exceptions it must serve.
Connect agreed office extensions across branches using a supported PBX and network design. Dial plans, authorised routes, connectivity and outage behaviour are confirmed; inter-branch calls and public telephone service have different dependencies.
For Multi-Branch Telephone, confirm extensions, sites and number plan, trunks, call groups, IVR and recording policy, LAN, VLAN, PoE, QoS, failover and administrator.
List branches and extensions, PBX ownership, inter-site connection, permitted dial routes, numbering, codec compatibility, public trunk responsibility and behaviour when a branch link fails.
Map Source & uplink → Core transport → Distribution edge → Managed endpoint for Multi-Branch Telephone and identify every interface owned by HJ, the customer, ISD supply or an appointed specialist.
Call quality and number availability depend on LAN, internet and carrier services; emergency calling, recording consent and billing need explicit ownership. Final models, capacities and quantities still follow survey, compatibility and availability.
Available call features depend on the PBX, endpoints, provider and licences. Telephone subscriptions, number porting, recording, emergency calling and staffed response are not assumed included.
For Multi-Branch Telephone, record internal and external calls, transfer, hunt, IVR and voicemail, failover, paging and configuration backup; also agree link, throughput or power test, addressing and segmentation record, label, route and handover schedule before handover.
Test agreed branch-to-branch and public call routes, transfer and caller identity where supported. Document numbering, access restrictions and behaviour during a planned link-loss test.
HJ coordinates assessment, engineering, installation, integration, testing and lifecycle support only for the scope recorded in the quotation. ISD handles catalogue, model, datasheet, supply and availability enquiries. Customer, consultant, builder and appointed-specialist responsibilities remain explicit.
Final scope, quantities, compatibility, access, programme, availability and responsibility are confirmed during assessment and quotation.
This focused topic remains connected to its complete system owner. Final models, quantities, interfaces and included work are confirmed in the assessed quotation.
