Adapters with support of G723, G729, and GSM codecs I have been looking for a FXO/FXS SIP adapter for home use, which supports GSM, G723, G729 compression codecs. It appears that there is none. And the only hardware VoIP phone, which supports GSM is Grandstream GXP2000. Is it correct?
My ISP is Bell Sympatico DSL (Canada) if it makes any difference. |
