Question

I just updated the app on my iPhone (4) and now ALL outgoing calls get a recording saying number cannot be dailed

Answer 1

Please check if you have number rewriting on in Zoiper. (in the account settings.

Maybe some prefix is getting changed / removed / added.

I don't see an other reason why it could fail (other than a server issue).

Codecs are correct right, username and password seem correct.

You might want to ask the provider why the calls are failing, but the prefix is the likely culprit.  (The message is played by the server, zoiper does not have such message)

Thanks - not the number re-writer (but interesting to know that is there and the international number settings below that).

Zoiper is failing on 800, 888 numbers - then I tried other local and long distance numbers, cell and landlines - none working.

Perhaps it is just this location - but have used app here before successfully.

Grateful for any other suggestions.
