Hello Community!
Would like to as if anyone here have experience testing Half rate /AMR in osmo-nitb and
Freeswitch. Basically we are testing it in our lab with our devices Samsung Note 9 and
iPhone and we are having issue / errors as observed during testing. Below are the details
of the NITB we using:
