[Serusers] Handling of REFER messages

Hi, I am trying to do a peculiar task and I want to find out if SER can
do it. The issue is with call transfers which generate the REFER
message. I am connecting a Nortel voip switch to Asterisk via sip. I
need to have all call transfers generated by the Nortel switch to not
reach Asterisk as all the call transfers are done to dids/extensions not
found on the Asterisk PBX. Instead I would like to intercept / re-route
them back to my Nortel switch which can handle it. Currently I have a
workaround using an Audiocodes gateway with loopback cables. The
Audiocodes when sees the transfer request sends it back to the Nortel
switch. As this is a wasteful use of expensive hardware I would like to
find another method to do this. Can someone let me know if this is
possible with SER? And if it is which functions do I use? Any help is
greatly appreciated.
