[SIPForum-techwg] Media line Transparency

[Bharrat, Shaun]

All:

I missed this in Section 6.1 before...

SP-SSEs
1. MUST accommodate unsupported (and unrecognized) media types by passing SDP media lines and attributes unchanged, and 

Am I misreading this or is this saying that an SP-SSE effectively is
barred from mediating or policing the media should the SIP-PBX provide
an unknown codec? I cannot understand how this can be a MUST. If
an enterprise pays for G711, the SP-SSE should not be obligated to
accept anything else, whether or not it understands the other media
lines and/or codecs.

Can someone elaborate.

Thanks and cheers,
Shaun
