(Strategic Takeaway) {#so-what} Voip Duocom - softphone SIP is a business app that is free with in-app purchases. It holds a 3/5 rating from 48 reviews. > **Bottom Line:** Restoring core functionality is the only path to retaining existing B2B subscribers, as the current non-responsive state renders the service unusable for its intended business purpose. **Best for:** Business professionals and companies using Duocom Europe S.L. virtual telephony services who need to manage office lines remotely. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit launch sequence because users report the app is non-functional → restore core telephony utility ### Outlook: Declining The business softphone market is consolidating around providers that offer high-frequency updates and reliable call quality. Voip Duocom's current maintenance-only posture leaves it exposed to competitors, and the immediate consequence is the loss of the existing B2B user base to more stable alternatives. - 🔴 The 10-month release gap indicates a lack of active maintenance, which erodes user trust in the platform's reliability for business communications. - 🔴 Critical functional failures at launch prevent users from accessing telephony services, leading to immediate churn and negative sentiment. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3/5 | | Total Reviews | 48 | | Sentiment | Upset (10/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Voip Duocom - softphone SIP** (this app) | 3/5 | Upset | Duocom Europe, S.L. | | [Groupon Merchant](https://marlvel.ai/apps/groupon-merchant) | 3.0/5 | n/a | Groupon, Inc. | | [긱톡 - 재택부업, 프리랜서, 단기알바 정보 플랫폼](https://marlvel.ai/apps/com-gigtalk-gigtalk) | 4.5/5 | N/A | Nextstep Inc. | | [두란노](https://marlvel.ai/apps/app--971) | N/A/5 | N/A | Duranno | | [쿠펀치](https://marlvel.ai/apps/coupang-app-coupunch) | 1.0/5 | N/A | Coupang Corp. | | [아지트 - 함께 소통하는 업무용 커뮤니티](https://marlvel.ai/apps/app--797) | 3.0/5 | N/A | Kakao Corp. | ## Company Profile - **Developer:** Duocom Europe, S.L. - **Website:** [https://www.duocom.es/llamada-voip-movil.php](https://www.duocom.es/llamada-voip-movil.php) - **Social:** [Facebook](https://www.facebook.com/duocom.europe.sl) · [X/Twitter](https://twitter.com/duocom_es) · [YouTube](https://www.youtube.com/user/DuocomEurope) · [LinkedIn](https://www.linkedin.com/company/duocom-europe-s-l) ## Data Sources & Links - **App Store ID:** 578909037 - **Google Play ID:** es.duocom.softphone - **Dev Site:** [Official Website](https://www.duocom.es/llamada-voip-movil.php) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Groupon Merchant*](https://marlvel.ai/apps/groupon-merchant) (Groupon, Inc.) · 3.0/5 Rating - [*긱톡 - 재택부업, 프리랜서, 단기알바 정보 플랫폼*](https://marlvel.ai/apps/com-gigtalk-gigtalk) (Nextstep Inc.) · 4.5/5 Rating - [*두란노*](https://marlvel.ai/apps/app--971) (Duranno) · N/A Rating - [*쿠펀치*](https://marlvel.ai/apps/coupang-app-coupunch) (Coupang Corp.) · 1.0/5 Rating - [*아지트 - 함께 소통하는 업무용 커뮤니티*](https://marlvel.ai/apps/app--797) (Kakao Corp.) · 3.0/5 Rating - [*シフオプ*](https://marlvel.ai/apps/shift-management-service-to-support-optimal-placem) (Recruit Co.,Ltd.) · N/A Rating - [*아임히어 - 모바일 출결 관리 앱*](https://marlvel.ai/apps/com-imhere-client-student) (LFin) · 2.9/5 Rating - [*카매니저 - 중고차 딜러전용 전국 매물공유 플랫폼*](https://marlvel.ai/apps/kr-co-autocafe-carmanager) (atonmobility appmaster) · 3.0/5 Rating - [*금호고속 셔틀*](https://marlvel.ai/apps/kr-co-kumhobuslines-shuttle-route-passengernew) (kumhoexpress) · 2.1/5 Rating - [*쿠팡이츠 배달 파트너*](https://marlvel.ai/apps/coupang-eats-delivery) (Coupang Corp.) · 2.6/5 Rating ## Frequently Asked Questions {#faq} ### Is Voip Duocom free to use?
