Send OTP SMS to Customers in Serbia

Honestly, we thought this would take weeks. It didn’t. We had local numbers set up in under 48 hours. IVR was built in less than a day. Calls started coming in. And just worked. Customers reached the right people. Support agents were less overwhelmed. It’s one of those things that quietly solves a bunch of problems at once. We barely had to think about it after launch. Which is ideal.

We’ve been using Teliqon to power our outreach at Panem, and honestly, it’s been a low-effort, high-impact win. The auto dialer saves our team a ton of time, and the ability to call with local numbers has noticeably improved our response rates. We also run bulk SMS campaigns to promote our SEO audits and offers — it’s fast, reliable, and easy to manage once it’s set up. The UI’s a little basic, but their support team is quick and helpful, so it balances out. If you’re doing any kind of lead generation or client follow-up, this setup just makes life easier.

Reliable Lead Validation API That Cleans Up Your CRM in Minutes. Teliqon’s Lead Checker and Reputation Checker APIs were dead simple to integrate, and they immediately started flagging bad numbers and sketchy entries in our clients' CRMs. It helped clean up dirty data before any outreach happened, which boosted answer rates and reduced bouncebacks. Support team was responsive via chat, even during integration. Prixing was quite flexible and Lead Checker tool really helped save time for the team. Before this, our client’s sales team was wasting time calling fake or unreachable numbers. Their CRM was full of junk data, which killed productivity and skewed performance metrics. With Teliqon, we filtered bad leads right at the source — cleaner campaigns, fewer failed dials, and better conversion rates. It also saved us dev time by not having to build our own validator from scratch.

Organized Communication and Faster Response Times with Teliqon. What we like best about Teliqon is that it helped us make communication much more organized as our workload grew. We reduced missed calls by around 27% and improved response time by nearly 34%, which made day-to-day coordination between teams much easier. We also appreciated how responsive and practical their support team was during setup and ongoing use. Teliqon helped us solve issues with delayed responses and communication getting harder to manage as the number of requests increased. It became easier to keep processes organized and avoid losing important inquiries between teams. This improved coordination internally and helped us respond to clients more consistently.

Teliqon helped us launch outbound sales in 24 hours. The ease of setup. We were up and running within 24 hours — zero technical blockers. Also, the Auto Dialer efficiency: skipping voicemails and dead numbers makes a big difference in actual talk time. The CRM integration keeps everything clean, and local presence dialing really boosted our pickup rates. Plus, we appreciated the responsive support — they actually care. I wish some advanced dashboard features (like detailed performance comparisons by campaign) were more customizable but it's rather feedback than an obstacle, everyting worked perfectly We wanted to start exploring outbound sales but had zero infrastructure in place. Our dev agency mostly grew through referrals and inbound leads, but we knew we were missing out on opportunities by not proactively reaching out to potential clients — especially startups and mid-sized tech companies that may not find us organically. The goal wasn’t to build a massive call center overnight — just to test the waters and see if cold outreach could move the needle.

Scalable and automation-driven solution. As an IT outsourcing provider, we needed a way to establish a local presence in multiple countries so that clients could reach us without worrying about international call costs. Additionally, when clients receive calls from a local number, their loyalty is higher, and they are more likely to answer, perceiving it as a call from a local company. Teliqon’s virtual phone numbers were the perfect solution – we obtained local numbers in the UK, Netherlands, Poland, Israel, and Ukraine, allowing us to maintain seamless communication with clients and partners, whether between scheduled Google Meets or during urgent situations. The setup was fast and hassle-free, and the integration with our Cloud PBX and CRM made managing calls effortless. Since implementing Teliqon’s solution, we’ve seen a huge improvement in client engagement and response rates — more answered calls, smoother collaboration, and a stronger global presence. Huge thanks for a scalable and automation-driven solution!

Reliable, Easy, and Actually Saves Time – Teliqon Does What It Promises Honestly, everything just works. We plugged in Teliqon and didn’t really have to think about it again — it just does its thing. Calls go through, messages get delivered, the dashboard looks clean, and we’ve barely had to touch support (but they’re always there when we do). It’s one of those tools that fades into the background in the best way possible. Super smooth, reliable, and low-effort from our side. Big fan.

Effective tool for CRM data check Honestly, Teliqon handled a problem we didn’t even know was this annoying until we saw it solved. Our clients’ B2B tools were getting bogged down by garbage leads — fake numbers, flagged numbers, etc. Once we dropped Teliqon’s Lead Checker into the flow, we started seeing cleaner call results, fewer errors, and better campaign performance. Solid tool, and their team is responsive and chill to work with. Would definitely use it again on future CRM or sales platform builds. Pros Super easy API integration. We used the Lead Checker + Reputation Checker to clean up client CRM data before syncing it to live environments and third-party integrations. Helped us flag bad numbers and filter out spam-trapped leads. Also, the validation was really fast. Saved our devs a ton of time building custom checks. It’s also one of those rare tools that quietly increases internal efficiency while also directly reducing operational costs. Huge win. Cons The docs were solid, but we wouldn’t mind a couple more ready-to-use code snippets in different languages. Not a blocker, just would’ve made onboarding even faster.

Made our support local without opening offices We used Teliqon’s Cloud PBX to set up phone support in six countries. All virtual numbers, no offices, no complicated onboarding. We just needed a way for our VAT clients to call a local number and get through to someone in their language. Teliqon gave us that and more. Their IVR was easy to set up, and we could route calls by language and team availability. Our support agents are in three different time zones, but calls still land in the right place. The call quality was great, the dashboard made sense, and their support team helped us get started quickly. Honestly, it solved a real issue for us. We now look more local and reliable to our clients, and internally it saved our team a ton of coordination back-and-forth's.

The fact that they support crypto payments was oddly convenient. Thanks to Teliqon.io, the client's OTP delivery rates have improved from 84% to 98% in the first month. Support tickets related to not receiving codes have dropped almost entirely. The team is responsive, timely, and quick. They check in regularly, ensure everything is working, and suggest tweaks. We integrated Teliqon’s SMS API into our platform to send one-time passwords (OTPs) for login, sign-ups, and sensitive user actions. The setup included basic authentication workflows, error handling, delivery tracking, and fallback mechanisms. We also needed support for different regional formats and compliance needs, which they helped with. It was a plug-and-play process with some light back-and-forth on custom headers and templates. Took less than a week total.

The project was mainly about making communication more manageable as the number of incoming requests continued to grow. Teliqon helped us set up a Cloud PBX, connect Virtual Phone Numbers for different regions, and organize communication analytics so we could better understand how requests move between teams. They also configured the routing structure and centralized communication processes, which made daily coordination much easier. After implementation, we noticed that missed calls dropped by about 31%, while response speed improved by nearly 28% because requests were being distributed more clearly and consistently between departments.

What we like most about Teliqon is how effectively their call tracking, cloud telephony, and smart call routing solutions improved our communication processes. After implementation, we reduced missed calls by nearly 29% and improved lead response speed by around 33%. The platform is stable, easy to manage, and gives us clear visibility into where leads come from and how they are handled. Their technical team was also very responsive during setup and explained all details clearly. One limitation we noticed is that most of the documentation is currently available only in English, so some onboarding questions required additional communication with support. However, their team responds quickly and provides detailed explanations. We use Teliqon for call tracking, cloud PBX, and smart call routing to improve lead management and communication efficiency.
