Dafür war es aber eigentlich gedacht. Anrufen klappt, aber halt nicht angerufen werden, wenn man unterwegs ist und nicht aktiv davor sitzt, die App nicht aktiv ist und das iPhone in der Tasche steckt. Das gleiche erreiche ich auch mit Ftitz!fon, ohne die Fritzbox zu vergewaltigen und alles zu öffen für das Internet. Schade, hatte mir mehr davon versprochen. Daher wieder gelöscht, Fritzbox wieder geschlossen für Zugang von aussen und Fritzfon mit Wireguard wieder aktiviert. App gelöscht, geärgert und Widerruf an Apple geschickt. Wollte nicht 7,99€ in den Müll schmeissen. **Developer response:** Das sollte so nicht sein – eingehende Anrufe sollten auch bei gesperrtem iPhone und geschlossener App funktionieren. Bitte kontaktieren Sie uns unter support@acrobits.net, damit wir Ihre Konfiguration prüfen können. Wenn möglich, senden Sie uns auch ein SIP-Log mit. ### 2/5 — Der Link zum App-Support geht nicht ☹️ *2026-04-03* Wie kann ich den Support erreichen? Auf der iWatch werden eingehende Anrufe nicht angezeigt, wohl aber verpasste Anrufe 🤔 Mittlerweile verliert die App mehrmals am Tag die Verbindung 😬 **Developer response:** Sie erreichen unser Support-Team unter support@acrobits.net Bitte senden Sie uns Ihr Gerätemodell, die App-Version und, wenn möglich, ein SIP-Log, damit wir die Verbindung und die Apple-Watch-Benachrichtigungen genauer prüfen können. ### 3/5 — スピーカーでの音量変更 *2026-01-10* 自宅のひかり電話ルーターと同一ネットワーク上で通話する際、スピーカーにすると音量変更ができなくなるバグがあります。早急にご対応願います。 **Developer response:** ご報告ありがとうございます。詳しく確認いたしますので、support@acrobits.net までご連絡ください。端末情報、アプリのバージョン、可能であればSIPログもお送りいただけると助かります。 ### 3/5 — ‘ Messasege too large’ エラーで発信出来ない *2025-10-10* アップデートがあった後くらいからタイトルの通りのエラーが出て一切発信ができません。 例外的に同じbrastel同士の番号に掛ける場合は問題なく発信出来る様です。 着信関しては問題ありません。 解決策ご教示頂けると幸いです。 **Developer response:** ご不便をおかけして申し訳ありません。「Message too large」エラーについて、サポートチームが詳しく調査いたしますので、support@acrobits.net までご連絡いただけますでしょうか。 ### 2/5 — Parou de funcionar no iphone *2025-08-22* O aplicativo parou de funcionar no iphone sem mais nem menos, gostaria de suporte para resolver esta situação. Obrigada **Developer response:** Obrigado pelo contato. Para que possamos ajudar da melhor forma, pedimos que abra um ticket diretamente com nosso time de suporte em support@acrobits.net ### 5/5 — Push notifications *2025-06-14, version 5.13.47* Does not support Apple Watch ### 5/5 — Sehr gute App *2025-06-11* Nicht alles ist bei der deutschen Übersetzung leicht zu verstehen. Aber funktioniert sehr zuverlässig. **Developer response:** Vielen Dank für Ihr Feedback! Doch, es ist möglich, Rufnummern zu sperren. Die Schritte dazu finden Sie unter folgendem Link: https://faq.acrobits.net/blocking-acrobits-softphone-incoming-callers Falls es nicht funktioniert oder Sie Fragen haben, kontaktieren Sie uns gerne unter support@acrobits.net. ### 3/5 — 音質 *2025-06-08* 便利なアプリですが、通話音質が良く無いです。設定で調整できると良いのですが。 **Developer response:** 通話音質についてご不便をおかけして申し訳ありません。 詳しく状況を確認させていただきたいので、以下のメールアドレスまでご連絡ください： support@acrobits.net どうぞよろしくお願いいたします。 ### 5/5 — Great! *2025-05-12, version 5.13.37* Thank InterTelecom for suggesting Softphone. Nice smooth app. Does the job as it should. Very happy ### 5/5 — Excellent, just works! *2025-04-04, version 5.13.19* I‘m using this App for years and it just works. Thank you to the developer. ### 5/5 — By far the best *2025-03-16, version 5.12.35* I use this app on a daily basis and it works every time. I love it. ## Most critical reviews (10 lowest-rated) ### 1/5 — 이번 업데이트가 실행되지 않습니다 *2026-06-26* 오늘 업데이트 했는데 앱이 실행되지 않습니다 수정해 주세요 **Developer response:** 안녕하세요. 업데이트 후 앱이 실행되지 않아 불편을 드려 죄송합니다. 25.3.92 버전에서 앱이 실행되지 않는 문제가 있었고, 이후 업데이트에서 수정되었습니다. App Store에서 최신 버전으로 업데이트해 주시면 정상적으로 실행됩니다. 그래도 문제가 계속되면 acrobits.net/support 로 iOS 버전과 기기 모델을 알려주시면 바로 도와드리겠습니다. 감사합니다. ### 1/5 — Useless *2026-06-24* Useless, does not register on local net to asterisk. No push on vpn. Expensive and totally useless. **Developer response:** Sorry this has not worked out for you. There are two separate things here. Registration: the app registers to whatever host the account points at, so an Asterisk that is only reachable on your LAN will register on Wi-Fi but not from outside. Push is the bigger one: push notifications are delivered through our push server, which needs to be able to reach your PBX. An Asterisk that only exists behind a VPN is not reachable from our side, so push cannot be delivered, and the account has to stay awake over the VPN instead. Both setups can be made to work, and we are happy to go through yours. Reach us at acrobits.net/support with your account configuration and we will help you get it running. ### 1/5 — Falsely Advertised *2026-06-19* States right in the screenshot that it supports messaging. It does not. **Developer response:** Acrobits Softphone does support messaging, but it requires your VoIP provider to have messaging enabled on their platform. The app itself does not provide messaging independently - it depends on your service provider's configuration. If your provider supports it and messaging still isn't working, we'd like to help. Please reach out to your VoIP provider first, and if the issue persists, contact us at support@acrobits.net with your setup details ### 1/5 — 電話応答したら応答画面が二重になってどこからかかってきたかわからんです！ *2026-03-23* 電話応答したら応答画面が二重になってどこからかかってきたかわからんです！ **Developer response:** ご不便をおかけして申し訳ございません。状況を詳しく確認したいので、support@acrobits.net までご連絡ください。可能であれば、端末情報とアプリのバージョンもお知らせください。 ### 1/5 — 通話できない事は8割以上です *2026-02-22* Wi-Fi環境も良く、（数値でも確認）、ネット環境も良い場所でも、こちらの声が相手側に聞こえない事が多いです。　非常に困ってます **Developer response:** ご不便をおかけして申し訳ございません。片側通話の原因を詳しく確認したいので、support@acrobits.net までご連絡いただき、可能であればSIPログもお送りください。 ### 1/5 — Eingehende Anrufe klingeln nicht *2025-12-28* Für Telekom angelegt, soweit so gut. Abgehende Anrufe gehen, eingehende kommen leider nicht an. Schade, ansonsten wäre das eine Alternative geworden. ### 1/5 — No microphone support. *2025-10-15* App upgrade result in no microphone support to use. Say go to Settings > Privacy > Microphone with no option to turn on. No iOS update have occur. **Developer response:** Thank you for your feedback and sorry to hear about the microphone issue. Please email us at support@acrobits.net so we can check your case in more detail. ### 1/5 — [Prb] a "temporarily unavailable" message or an announcement stating "your call cannot be completed *2025-09-12* I'm experiencing an issue with my phone service. For the past few days, when I try to make calls to US phone numbers and 050 numbers, I receive a "temporarily unavailable" message or an announcement stating "your call cannot be completed." The calls do not go through. Interestingly, calls to domestic numbers are working fine with "my050," an Acrobits OEM. I'm requesting an urgent resolution to this problem so I can make international and 050 calls as usual. **Developer response:** Thanks for reporting this, we’d like to take a closer look. Please email us at support@acrobits.net, and include any call examples. That’ll help us investigate the issue and get it resolved faster. ### 1/5 — Deduct subscription without inform user *2025-03-20* It deduct money without not letting user know. And even no use of the app. **Developer response:** Hey, we handle the app’s development, but billing and call charges are managed by your SIP/VoIP provider. We recommend reaching out to them directly for assistance. ### 1/5 — The transfer button is missing. *2024-11-27* After updating to Groundwire version 5.12.16, the transfer button is no longer displayed. Please address this issue. **Developer response:** There should already be an update out where this is resolved.We apologize for the inconvenience. ## Most praised reviews (10 highest-rated) ### 5/5 — Самое лучший SoftPhone! *2026-06-13, version 25.3.89* «Считаю, что этот SoftPhone — один из самых надежных и стабильных среди всех существующих. Тем не менее, хотелось бы улучшить эргономику и юзабилити более современным, так же саму клавиатуры набора номера, сделав её раскладку более привычной, например, как на iPhone, было бы прекрасно сделать дизайн под 26 версию IOS, добавить жидкое стекло. Было бы удобно добавить возможность скрывать неиспользуемые вкладки (такие как «Избранное» или «Контакты»), а также настраивать внешний вид: устанавливать собственный фон и рингтон, добавить возможность менять цвет кнопки , фон, устанавливать свои ринг - тоны на звонок. Спасибо за вашу работу!» ### 5/5 — Reliable, one time fee *2026-05-23, version 25.3.76* It's a reliable soft phone, for your existing sip provider with no recurring fees for their app. Works well on WiFi or on lte/5g in an urban area, the only feedback I'd have is a super minor point: the icon always throws me off because nothing about it says "dialer" so I have to hunt for it every time I use it because I forget what it looks like . ### 5/5 — Excellent Skype replacement *2026-03-15, version 25.3.58* Fantastic app. Was looking for a solution to keep my UK number following the demise of Skype so loaded this app with an account from www.aa.net.uk (ported Skype number). Works perfectly, excellent call quality, no battery drain issues, recommended ### 5/5 — Troubleshooting *2026-02-09* I had an issue some days ago, and I was really impressed about Acrobits’ team taking care of it, answering my request and giving me feedback. Thanks and congrats. ### 5/5 — Ótimo app *2026-02-06* Único testado é que funciona perfeitamente. Já uso a alguns anos. ### 5/5 — Best VOIP Client *2026-01-26, version 25.3.32* Souhlasim. nejlepsi voip client na iphone. ### 5/5 — Twilioクライアントとして便利です *2026-01-16* 思いのほか評価が低いですが個人的には数年使っていますが不便感じたことはないです。 あまり頻繁に電車使用しないのとtwilioのクライアントとして使っているので使い方が一般的ではないかも知れませんが、ありがたく使わせてもらっています。 あとアップデートも頻繁でメンテされているのが良いです。 **Developer response:** 温かいレビューをありがとうございます。長くご利用いただき、またアップデートやメンテナンスへの取り組みも評価していただけて、とても励みになります。今後も安心して使えるアプリをお届けできるよう努めてまいります。 ### 5/5 — Amazing *2025-10-16* Absolutely fantastic! I’ve tried several of these Softphone apps and this is the first one I’ve tried that actually works. I’m totally impressed, and that’s not easy to do. **Developer response:** Thank you so much for your fantastic feedback!. Your satisfaction means a lot to us! ### 5/5 — Avoid at all costs *2025-08-02, version 25.2.19* This company is an absolute scam. I requested a refund for this app so I could get Acrobits Groundwire and they rejected me for no reason. It’s made by the same company but it’s a different app. It looks exactly the same. Ridiculous. ### 5/5 — Great technical support *2025-06-22* App is easy to use and tech support is very helpful. **Developer response:** Hi Jedsda, thanks a lot for the 5 stars! Really appreciate you taking the time to share your experience. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
