[SIPForum-techwg] Can we please have at least one real codec

[Roni Even]

Like Dan I think that one advantage of IP phones is that they can use higher
quality codecs, 7 or 14 Khz. If you leave one codec as Mandatory the
question will be what about the media line transparency. Is the decision
about which codecs are supported is left only to the SIP PBX / SP to decide
or can SIP phone used decide which one they would like to have.
