[Asterisk-Users] Asterisk->AS5350 misplaced RTP to 127.0.0.1 (AS5350 party don't hear)

[Goran Dj.]

My configuration is:
[ISDNPRI] -- [CISCO AccessServer AS5350] --<H.323>-- [ASTERISK] -- 
[CISCO ip phone 12SP+/Skinny]

When call is initiated from IP phone -> Asterisk -> AS5350 -> ISDN
everything working ok (RTP is ok).
But, when call coming from ISDN -> AS5350 -> Asterisk -> IP phone
IP phone party can hear ISDN party, but ISDN (incoming) party canNOT
hear IP phone party
because RTP stream from Asterisk is sent to 127.0.0.1 instead to real IP
address of AS5350

Here is H.323 debug, for both situations:
