country code Yealink t21

[michael10fr]

I find a Chrome extension that allows for a click to call.
the problem is that this extension does not know recognize the country code?
For example if a telephone number, by how +33148492032, extension will number 148492032 and 148492032 0 no.
so I put a rule in the Yealink T21 table if there is the prefix 33 he puts into the account by 0 1 OK

It Works

but the problem is that if I have clients who will find another prefix, then the tread here more ??

any rule or term regular, I just put in the Yealink for any country prefix or replace the Yealink know to make the right nuemro with the correct prefix the good land?

thank you for your help
