The end result must feel like a single, seamless conversation.

I need a Japanese national DID or any other VOIP number that can reliably forward calls to my chosen destination. The line will serve both personal and business purposes, so stability, clear audio and the ability to register the caller ID on common soft-phone or SIP devices is essential. Please supply, activate and demonstrate the number working via simple call-forwarding within the shortest possible time; my preference is ASAP. If you already have an inventory of Japanese DIDs, even better—let me know the formats available and any documentation requirements. Acceptance is straightforward: once I can receive and place test calls through the number without drops or quality issues, the milestone is cleared.

I need a reliable professional who can take over my customer service line and focus solely on answering incoming inquiries. Calls are usually straightforward questions about product availability, basic troubleshooting, and shipment status, but they set the overall tone of the brand, so every interaction must feel warm, clear, and resolved on the first attempt whenever possible. This is strictly phone support—the live chat and email channels are handled internally for now—so you should be comfortable working with a soft-phone or VoIP setup, keeping concise call notes in our CRM, and following simple escalation rules for anything you can’t solve during the first call. Key deliverables include: • Consistently picking up within our agreed-upon ring window &bull...

Every incoming fax must be archived automatically as a PDF, and all administration—including queue monitoring, user setup, and log review—has to be handled through a clean, browser-based interface.

** ONLY AFRICAN LOCAL PERSONS ALLOWED. NO OTHER NATIONALITY ** I need to confirm voice routing between Pakistan and Africa. The task is genuinely simple: be in any African country, keep your local SIM active—MTN, Airtel, Orange or whichever operator you normally use—and be ready for two short calls. 1. I will dial your mobile from my Jazz network in Pakistan; you just pick up and confirm the audio is clear. 2. You then return the call to a Pakistan number I provide. That’s it—one successful incoming, one successful outgoing call. Total talk time is under one minutes and I release the fixed $10 as soon as both legs are verified. Please bid only if you are physically within an African country and can complete the test immediately.

I need a fluent English speaker who can jump straight into handling both inbound and outbound calls with our business partners. The role sits at the intersection of customer happiness and light technical troubleshooting, so you’ll spend most of your day guiding partners through product-related questions, documenting each interaction in our CRM, and making sure every conversation follows the script and brand tone I’ll provide. Because you’ll be the first voice many partners hear, I’m looking for someone who stays calm when lines are busy, keeps notes organised, and can translate a technical answer into plain language on the fly. Prior technical support experience is essential—if you’ve ever walked someone through a configuration step or explained why a...

I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

My Panasonic Ns500 PBX sits on but cannot “see” the rest of my network. Everything else flows through a FortiGate 60F firewall, a FortiSwitch 424E-Fiber core, and a FortiSwitch 124F-FPOE at the edge. I need someone to shape the network so this Panasonic box can handle VoIP communication smoothly. What I already know • The PBX will run pure SIP. • Dedicated VoIP rules on the FortiGate are required; simple, generic access is not enough. What I need from you • Review the current FortiGate policy set, VLAN layout, and switch port profiles. • Create or adjust firewall rules, NAT, and any SIP ALG or helper settings so that SIP registration, signalling, and RTP streams pass without one-way audio or dropped calls. • Tag or untag the appropriate swi...

I’m looking for a reliable ViciDial pro who can jump in each day and keep my dialer running smoothly. The core of the job is straightforward but must be done consistently: • Run the standard performance and list-based reports I specify, download them, and drop them in our shared folder before end of day. • Import new lead files (CSV) as they arrive, map fields correctly, and verify the list is live. • Check that every active campaign’s leads are sitting in the hopper in the right quantities so agents never run dry.
