Why is OPUS codec not available in the free version? Isn't an open source codec?
Zoiper GOLD does not unlock only H264 and G729. All the other audio codec are unlocked with the Zoiper GOLD purchase.
Sorry to re-iterate.
Bottom line, OPUS is regarded as a premium option when (imo) it shouldn't be, as it is open source.
Anyway, thanks for the answer.
