Hi, 

I have a serious problem to configure Cisco AS5XXX and Asterisk , 

I trying to use asterisk for 

PSTN(A)----> Cisco AS5xxx ----> ASterisk---->PSTN(B) 

(No Nat, no Firewall)

I hear (on the PSTN(A)) clearly what the other person is saying, but the
other person (on the PSTN(B) side) hears nothing from PSTN(A).

I use tcpdump for debug de rtp trafic, and ouput contains

Where

 x.x.x.x = ip address of Astersik
 y.y.y.y = ip address of Cisco


Two types of codecs were proven ( ulow, g729 ).

When use the Asterisk with Sip phones everything works well.
 
        SipPhone------>Asterisk------->PSTN(B)     

The configurations, are the usual ones (from the wiki). the version of
asterisk is 1.0.3, the linux is  FC2.


Please help me.
