while trying the client on SIP provider keep returning the unknown codecs, how can the following codecs be added to the client ?
G729 is available with zoiper biz.
G726, g723 is not available
gsmfr and g711 are available are selected by default.
The codecs also exist on zoiper 5, with some extra codecs such as opus and g722
Really it's the GREATEST linux client, without a doubt.
I have a legacy OS in the environment, and Zoiper 3.3 working good, but it's possible add o manually include opus codec int he available lists for this client version?
Unfortunately no, backporting codecs is not simple and cannot be done.
