Hi All

Can anyone help me with the below scenario -

1) INVITE from UAC to UAS with SDP offer
2) Server replied with 183 and SDP answer (G.711 codec)
3) UAC sent PRACK
4) Now UAS sends 200 OK for PRACK
5) RTP packets start flowing for early media
6) Backbone core network supports BICC

End user (User-A) is not able to listen the voice message in early media.

Any pointers what may be the issue?
