iPhoneで、アプリが常駐しない

動作機種、動作環境を確認した上、導入しましたが、実用に耐えなかったため、2週間程で、解約しました。
電話でのサポートは丁寧で、親身になって頂いたと感じましたが、メールでの対応は、そうは感じませんでした。
解約のルールが特殊なので、規約をしっかり読んでから、契約することをお勧めします。

一時が万事

通話機能自体の品質に関しては他の方のレビューにお任せするとして、使い始めるまでも結構面倒です。
当方エンジニアの端くれのような者ですが「これはシステム側で対応すべきでは？」という事も客側でやらせるんだなという印象です。
※手間をかけさせて申し訳ないとも思ってなさそう…
要は一般的には当たり前に実装するような＋α的な機能がほぼ抜けており、それを客の不便(＋運用スタッフの方の人力)で巻き取らせてるんだろうなぁ…と。
同じくUIもこれでもかって位不親切です…
他の方のレビューにある「うちは悪くない、あなたのスマホがおかしい」にはそういった企業の姿勢を如実に表しているのかなと感じました。
中の方、お疲れ様です…

不具合でたら死活問題

カスタマーが機能してません。電話も出なければプラットフォームからも問い合わせ発信できないです。

架電はできないよ

1日30回架電すればかけ放題プランは適用されず、高めの通話料がごっそり持ってかれる可能性がありますw

業務では使わない方がいい

着信しない
着信をとっても音声が聞こえない
掛けても音声が聞こえない
業務で使うにはお粗末なアプリとしてしか言いようがない。
信用問題に関わるため、仕事での使用はおすすめしません。
