destination udp non 5060
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
