[SIPForum-discussion] Cisco AS5350 as VOIP g/w to handle redircet responses

[Mark R Lindsey]

Cisco calls this "SIP Redirect Processing". I believe you just need  
12.2T13 or newer, and to enable "redirection" in the "sip-ua" section  
on the IOS box.

http://www.cisco.com/en/US/docs/ios/12_2t/12_2t13/feature/guide/ftsipmaz.html

The interesting question is whether it's wise to use the AS5350 as SIP- 
to-SIP B2BUA or stateful proxy as you depict. While I know of many  
AS5300s in service in VoIP carriers, most folks would just send the  
call to the AS5350 when they're ready to terminate it to a TDM  
interface on the AS5350 itself.
