Call-Forwarding with hairpining

Hi,

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

sip

telephony-service

call-forward pattern .T

ephone-dn 16 dual-line

number 578

description Test-Phone

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.

thanks

Matt

How the call comes in ?

Where it's supposed to go exactly ?

You always need to clarify these basics before anything else.
