Best SIP App for IOS & Android?


What is the Best IOS and Android SIP app to use with FlyNumber?

Procedure on setting up an android app with flynumber account
Can I forward a number from here to oovoo
Creating local number Europe-USA
Getting sim card on landing
Transferring Landline to Flynumber

We really like Groundwire from Acrobits

You can keep the app completely off ( not running in the background ) and with their push technology still receive calls- big battery saver

Its a paid app but well worth the price, its stable and comes with many features

Requirements for incoming calls on Android
Call out from Flynumber

Can you set a different ringtone for the Fly Number Account that Co exist on same iphone with a regular phone line?



With the Groundwire app yes, it works with the built in IOS phone and ringtone is different ( can be changed)


Any point using the Phone systems app?

It’s directly from PXBww/Phone systems.


Yes there is, many users enjoy the ability to change the outgoing caller ID’s at a whim using the apps’ GUI ( user interface)


Ok. But I have the feeling this app works only with a Phone system SIP account installed as “Device”, right?
Can’t work with a custom SIP account?


Yes thats correct, the app would only work with our SIP
