Hello,

I am trying To perform a Call from Cisco call Manager to cisco sip-proxy via SBC 4600 .

Invite go through SBC To SIP-Proxy .

SIP-Proxy reply with Ringing and with UDP Source-Port 34222 ( NON 5060) and Dest-Port 5060

Now , Because of Source Port NON-5060  from SIP-Proxy  the SBC send messaged like PRACK with UDP Dest-port 34222 ( NON 5060)

so the SIP-Proxy don't answer for those messages ( sip proxy expect to 5060) and the call failed .

I also config NAT-Traversal to "NONE" in sip-interface and it doesnot help

My question is :

IS any idea that the SBC Ignore the NON-5060 port and send  port  5060 to SIP-Proxy ?

Tthanks

Eli
