Hello,

during some tests about SDP Insertion functionality on AP4600 with 920p11 release, I noticed that codecs (in this case, the second of the offer list, but this happens also with all the others in the list except the first and telephone event, so its not dependant on G729 rather than PCMA, that doesn't make any difference) are removed from 200 OK of the Initial Invite by the SBC (40.255.255.240 is core side, 20.255.255.240 is access) without any apparent reason (second call flow).
I downgraded to 920p6 (first call flow) without changing anything else in the configuration, and that does not happen, which is good.
