I have configured multiple SIP accounts for different purposes (e.g. some of them are cheaper for international calls to specific countries). They are all registered when I start Zoiper on iOS.
It would be nice if I could define some rules so that when I try to call a given number/contact a specific SIP account is used for it.
An extension of this approach could be to define e.g. that all calls of phone numbers starting with 00specific-country-code should be dialed via a specific SIP account.
I've seen such a feature available on e.g. FritzBoxes (https://en.avm.de/products/fritzbox/), which are very popular in Germany.
Is it possible to do something like this with Zoiper for iOS? If not, is planned to add such a feature? It seems like it is not something iOS specific and could be used by Zoiper on all supported platforms.
