    I need my Yeastar S20 PBX set up so that outbound calls flow cleanly without touching anything else already running on the box. 
My focus is exclusively on outbound routing: • Local calls must leave through the correct trunk and follow the national numbering format. • International calls should route through the same or a different trunk, whichever you recommend for best cost-control and reliability. I am not yet sure whether I need customised dial patterns or if the standard ones are enough, so part of the job is to review what I have, ask the right questions, and then implement the rules that make most sense. Please plan to do the work remotely through the web interface (or SSH if required) and give me a short hand-over note showing the patterns you entered and how to adjus...

    For the last decade a Debian machine on our vessel has been flawlessly running a set of Perl scripts that squash outgoing mail, hand it to an Iridium modem and deliver it to my shore-side mail server. Incoming messages follow the reverse path. Suddenly nothing moves in either direction. Here is what I already know and have ruled out: • The Iridium link itself passes its own internal tests. • DNS on the ship resolves the server name correctly. • Both the shipboard PC and the land-based server have been rebooted. • No recent configuration changes were made. • A Kerio Connect firewall sits in front of the mail server. Given that, I suspect the mail server is at fault, but I am not yet sure whether it still exchanges mail with any source other than the ...

    We use MicroSIP and Linkus most of our PBX Use Yeastar and Granstream. Our Dial Pattern is: if you want to call Egypt, you must remove the country code (+20******) to 70*****, and similarly for short numbers – the country code must be removed, and a '7' added automatically based on the chosen dial pattern. Also, from Egypt to Saudi, dial pattern +966 changes to 6055******. We need templates for these dial patterns with options to add or edit numbers dynamically, without displaying them directly in the dial screen. It should intelligently detect the correct country based on smart input. Additionally: - Desktop versions (Windows/macOS) - Mobile versions (Android/iOS with publishing to Google Play and Apple Store) - Backup and restore functionality included. - 6 months of su...

    I need a technician who knows FreeSWITCH inside-out to set up an automated voice-broadcasting system that will deliver a single marketing message to a list of contacts I will supply. The list arrives clean and ready for import, so your focus is the server build, dial-plan logic, and campaign workflow, not data cleansing or list generation. Here’s what I’m after: the call engine must pick numbers from my CSV, play one pre-recorded promotional message, handle basic call outcomes (live answer vs. voicemail) and generate a concise completion report with call status statistics. No per-recipient personalisation is required; the same audio goes to everyone, keeping the logic straightforward. I already have a VPS available; you are welcome to recommend tweaks to its specs if FreeSWIT...

    Vicidial is already live on our cloud server; what I need now is an on-site engineer in Hyderabad who can bridge it to a 32-port Dinstar GSM gateway sitting in our office. Your task is strictly configuration and testing—no fresh installs. Scope of work • Register the Dinstar gateway as a SIP trunk inside Vicidial, keeping a close eye on call-quality parameters and full compatibility with the gateway. • Analyse the current router, decide which ports must be opened, then set up forwarding so traffic reaches the cloud server cleanly. No predefined template exists, so you will determine the rules and apply them. • Run end-to-end test calls, troubleshooting the single audio problem we’ve seen so far: distorted sound.
