My NEC SV9500 PBX refuses to come back online after a routine restart. The system hangs during boot; I do not see telephones registering and I’m not sure whether any error codes flashed on the console because I wasn’t watching closely. I need an engineer who knows the SV9500 architecture, maintenance commands, and PCPro (or equivalent) to: • Connect remotely (or guide me onsite) to diagnose why the call-processing software is not loading. • Identify and clear any database, card, or processor faults preventing a full start-up. • Bring the PBX to an operational state where extensions are live and calls flow normally. Acceptance will be when the system completes its boot cycle, endpoints register, and we can place internal and external calls without drops...

I have just incorporated a company in Ireland and now need a local phone presence. The goal is to activate an Irish virtual number (or an eSIM if that proves easier) that is registered to the business and, above all, can reliably receive incoming SMS and receive Voice calls (outgoing not that important) If you have direct experience dealing with Irish carriers or virtual-number providers and can complete this quickly, I’m ready to start right away.

I’m setting up a dedicated tele-calling environment and need an IVR system built (or customised from an open-source/cloud platform) that focuses on efficient call routing for both inbound and outbound traffic. Core requirements • Inbound calls flow through multi-level menus and reach the correct queue or agent without delay. • Every inbound conversation is automatically recorded and stored with searchable time/date tags. • Outbound campaigns must dial through the same platform so agents work from a single interface, with those calls recorded in the same repository. Scope of work You’ll deploy, configure, and hand over a production-ready IVR. I expect guidance on menu design, prompt management, real-time monitoring and a clean dashboard where my team...

I need my Vicidial server configured for a fully agent-less “Press 1” outbound campaign that can run unattended. The list you will be dialing is a mixed audience of customers and cold prospects, so the system must handle large, varied datasets smoothly. Here is the flow I’m after: • The dialer places the call and immediately plays a promotional offer recording (I’ll supply the final WAV/MP3). • When the recipient presses 1, the call should be transferred in real time to a single phone number I will provide. • No agent will ever log in; the campaign has to launch, recycle and terminate automatically. You’ll take care of all campaign, list, and call-routing settings inside Vicidial, confirm audio formats, build the press-1 logic, and test li...

Our team—fewer than ten users in total—needs an efficient call-routing flow built inside Dialpad. I already have the seats created; what’s missing is the logic that decides who rings first, how overflow is handled, and how after-hours calls reach voicemail or an on-call mobile. Here’s the scope as I see it: • Map and implement the call-routing rules in the Dialpad admin console, using ring groups, IVR menus, or simultaneous/sequential ringing where appropriate. • Assign multiple roles so that a couple of us can act as admins while the rest remain standard users, without disturbing existing numbers. • Test each scenario—business hours, after hours, voicemail fallback—and document the settings so I can maintain them later. If you&rsquo...
