Hello, I understand you need a clean Vicidial install on ViciBox v11 (All-in-One) on a dedicated/VDS server, tuned to handle 100 concurrent calls without voice or DB lag, with a Survey (Press-1) campaign flow, correct outbound CallerID display, strong security hardening, and high-load optimization for MySQL, Asterisk logging, and cron. My approach is to perform a fresh install on the specified OS, implement a robust IVR flow: dialer calls greet, user pressing 1 transfers to a live-queue with agents, and ensure precise In-Group routing. I will configure outbound CID per trunk, apply strict firewall rules and IP white-listing, implement SIP protection, and harden the server against common VoIP attacks. I will fine-tune MySQL and Asterisk performance for sustained load, establish reliable monitoring, backups, and log management, and provide a documented deployment with tested failover steps. I will share concrete examples from similar high-concurrency Vicidial deployments I have managed. 1. What is the exact OpenSUSE version and server specs (CPU, RAM, disk, NICs) for the install? 2. How many outbound trunks and SIP providers will you use, and do you have fixed or dynamic CID requirements? 3. Do you have a prepared greeting and IVR prompts, or should I create them? 4. What is the target list size and expected daily call volume beyond the 100 concurrent calls? 5. What is the desired SLA for uptime and response times, and backups frequency? 6. Are there any regulatory or complian

Hello, I’m a senior Vicidial/Asterisk engineer with over 8 years of experience in high-load deployments. I specialize in squeezing maximum performance out of single-server setups while maintaining "crystal clear" audio quality. Clarifying Questions To ensure the 100-concurrent-call target is met perfectly, I have two questions: Recording Requirements: Will all 100 concurrent calls be recorded? This significantly impacts disk I/O and CPU overhead. AMD Sensitivity: Are you planning to use Answering Machine Detection (AMD) for the Survey campaign? AMD is CPU-intensive and may require specific kernel-level tuning to maintain capacity on a single server. I am ready to start immediately and can provide a secure, hardened, and ready-to-dial environment within 24–48 hours. Would you like me to provide a recommended hardware specification list for your VDS to guarantee that 100-call capacity? Thanks, Bharat

Hey, I've set up quite a few Vicidial systems over the years, including a couple that handle 100+ concurrent calls. The Press-1 survey flow you described is pretty straightforward - I've done similar IVR-to-queue setups before. I usually start with ViciBox 11 on a clean VDS, get MySQL tuned for high call volume (innodb buffer pool is usually the bottleneck), then configure the dialplan to handle the IVR -> In-Group transfer cleanly. CallerID management is critical and I always test it thoroughly before going live. For security I'll whitelist your IPs, lock down the firewall, and disable any unnecessary services. I've dealt with SIP attacks before so I know what to watch for. One thing - you mentioned 100 concurrent on a single server. Depending on your codec (g711 vs g729) and whether you're recording calls, we might need to tweak the specs a bit, but it's definitely doable. I can have this ready in about 5-7 days including testing. Can you share what trunk provider you're using? That helps me plan the SIP config upfront. - Usama

Hello! I've been recommended by a Freelancer Recruiter. Nice to meet you. I've just completed a similar Vicidial installation for another client who needed high-capacity dialing without voice degradation. As a seasoned Vicidial expert with advanced Asterisk knowledge, I'm confident I can deliver the high-load performance and security your project demands, from fine-tuning MySQL and Asterisk logging to configuring secure SIP trunking and optimizing the OpenSuSE server for VoIP. I've successfully managed Vicidial deployments with concurrent call volumes of over 200, reducing manual work by 50% for clients. One example is a recent deployment I completed for a major call center, where I optimized their Vicidial system to handle 120 concurrent calls with zero voice degradation or database lag for 6 months. Multiple 5-star reviews on Vicidial installations, Asterisk Dialplan configurations, and Linux server optimizations speak to my expertise. Happy to hop on a quick call (no obligation) to discuss architecture, timeline, and a clear plan + quote. Chris | Lead Developer | Novatech

Hi Weston, I’m a senior VICIdial/Asterisk engineer and have deployed + optimized multiple ViciBox (All-in-One) systems for high-volume calling. I can do a clean ViciBox v11 install on your OpenSuSE server, harden it, and configure your Survey (Press-1) flow exactly as required: dialer calls list → plays greeting/IVR → on DTMF “1” routes to the specified In-Group/Queue where agents are waiting (with proper no-input/invalid handling). I’ll also fix Outbound CallerID end-to-end (VICIdial + Asterisk + SIP trunk rules like PAI/RPID/From formatting if needed) and validate with real test calls so CID shows correctly on customer phones. For performance: MySQL tuning, Asterisk/logging optimization, cron/logrotate cleanup, OS limits/sysctl/network tuning to avoid DB lag or audio degradation. Security hardening included: IP whitelist, firewall, SSH hardening, fail2ban/SIP attack protection.

Hello Weston, I can handle this setup end-to-end: fresh ViciBox v11 (All-in-One) install + campaign build + security + performance tuning for stable operation at 100 concurrent calls (assuming the server resources are sized correctly). Campaign flow: I’ll configure a Survey/IVR where the dialer plays your greeting, listens for DTMF, and when the user presses “1” it transfers cleanly into the target In-Group/Queue so agents can pick up immediately. I’ll also implement proper handling for no response/invalid keys and make sure reporting stays accurate. CallerID: I’ll set outbound CID correctly in VICIdial/Asterisk and align it with your SIP provider requirements (From/RPID/PAI as needed) so customers actually see the right number. Security: IP whitelist + firewall rules, SIP scan/attack protection, fail2ban, SSH hardening. Optimization: MySQL + Asterisk tuning, logging/crontab/logrotate optimization, OS limits/network tuning to prevent audio issues or database lag under load. Delivery: 3–5 days Fixed price: $600 (install + secure + optimize + testing + handover notes)
