Hi I have a customer using Yealink T48G & T46G phones and an epygi qx50 in Australia. Their VOIP provider uses E164, which is a big pain for them, because they have to add 61 in-front of everything.
They want to be able to dial local numbers such as 40567392 (this is a local number of 07 40567392 or E164 61740567392)
national number such as
Mobile numbers such as 0412768891
You must have experience doing this before.
