This is fairly simple. But I figure it is best that you actually
understand what happens here.

In this scenario we have several different Asterisk channels:

1. SIPcall -> E1-port1

Incoming call from SIP generates a SIP channel. The dialplan context for
it is set in sip.conf .

You want it to generate a call to some DAHDI channel. This could be done
using e.g. Dial(DAHDI/g1)  (why g1? To what channels does it refer? See
documentation in chan_dahdi.conf to see  why I set it like that. Much of
it is arbitrary).

2. E1-port1 -> E1-port2

Loopback cable. 

It seems that you connected port 1 to port 4 rather than to port 2,
right?

3. E1-port2 -> sip extension

Now we have an incoming DAHDI call. The dialplan context is set from
'context' in chan_dahdi.conf (where exactly?) . Now you'll probably need
to use some dialplan such as:

  Dial(SIP/your-local-sip-extension)
