15.2(2)T2

Description (partial)

Symptom:
++ When CUBE is inter-working different payload values for RFC 2833 the payload value printed out by "debug voip rtp session named-events" is incorrect.

SIP Server1 ---SIP---( payload 97 )----SIP----CUBE-------SIP----(payload 101)------SIP Server 2.

CUBE natively inter-works the payload types , however the information printed out by debug voip rtp session named-events is incorrect ,  if you take debug voip rtp packets or packet captures the correct payload values are printed.
