[cisco-voip] tcl ivr SIP redirect or refer

[Justin Steinberg]

I can't speak for TCL but SIP Refer is supported.

voice service voip
 sip
  redirect ip2ip

With the above config, the router will send a 3XX Refer when an incoming SIP
call matches an outgoing SIP voip dial-peer.

I don't know if this helps your situation since you are using TCL.  Perhaps
if TCL can redirect the call to the outbound dial-peer IOS will take care of
SIP REFER.
