Funktioniert auch mit der nfon Cloud Anlage

Da die nfon-eigene App immer noch keine callkit-Unterstützung bietet, war ich auf der Suche nach einer entsprechenden Alternative und bin hier fündig geworden. Man benötigt von nfon die Zugangsdaten für ein sog. Unprovisioned SIP Device, die man in der Softphone App einträgt. Anrufe werden dank callkit-Support auf dem Sperrbildschirm angezeigt und priorisiert ggü. anderen Apps behandelt. Die Sprachqualität ist nach ersten Tests auch mit 3G noch mehr als passabel.

Top App - funktioniert einwandfrei!

Klare Kaufempfehlung für jeden der mit VoIP telefonieren will. Wir nutzen die App regelmäßig, wenn wir aus der Karibik o.ä. mal kurz zu Hause Bescheid geben wollen. Sip Account angelegt, App geladen, konfiguriert und schon kann’s losgehen. Bisschen Erfahrung muss man bei der Konfiguration haben, aber alles kein Hexenwerk. Statt 5-6 Euro / Minute aus dem Mobilfunk Netz im Ausland, rufen wir für ein paar Cent / Minute an. Und seit Jahren wird die App immer weiter entwickelt! Top!

Selten schreibe ich Bewertungen, aber diese App hat eine verdient.
Hab vor vielen Jahren Geld für diese App ausgegeben und sie wird bis heute gepflegt.
Push Service funktioniert auch einwandfrei
