I am trying to use call-forwarding to a "non" H450.1x compliant gateway.
I therefore assume I need to use HAIRPINING.
I have purchased and installed a PVDM-8 so the ISR can fucntion as my CME (ver 7.x) and an MTP too.
I have configured ...
voice service voip
allow-connections sip to sip
no supplementary-service h450.12
call-forward pattern .T
ephone-dn 16 dual-line
call-forward noan 91234567890 timeout 5
However, this is not working, the call ring for 5, then just disconnects.
I am guessing this is because I need to configure a dspfarm/MTP ?
I am struggling fing any accurate documentation to assist and I don't actually know if I really need to configure a MTP and dspfarm or not.
pls pls help.
