Subject: codec with different ptimes

Hello,

I want to know if the following SDP message is valid:

m=audio 6002 RTP/AVP 0 4
a=rtpmap:0 PCMU/8000
a=ptime:30
a=rtpmap:4 G723/8000
a=ptime:90

It suppose to announce two codecs with different ptimes. 

If it is correct, then an attribute lines 'a=ptime...' are connected to the 'a=rtpmap..' lines, and they are not just media level attributes but they are attributes of the attributes.....

Thank you,
