gsm voice quality will be good Codec choice is only relevant for the SIP leg, so use your normal choice in term of bandwidth/cpu/ptime. Gsmopen does not use codec, it runs internally in raw signed linear format. Let us (or me personally) know how the project goes. -giovanni Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618 On Wed, Jun 18, 2014 at 3:12 PM, Shlomi Agiv <shlomi.agiv@cell-buddy.com> wrote:
We intend to put freeswitch on an arm powered portable device, which will connect using a usb gsm stick and will serve as a wifi/gsm router
so, a call will connect two endpoints - one to the sip client through wifi, the other through mod_gsmopen to the gsm.
How will the voice quality be? which voice codec is most recommended?
