[Asterisk-Users] call transfer with consultation

[Antonio Diego]

Hello.

I am a spanish student, so excuse my English. I have
this HW:
- 2 X100P PCI with two analog lines plugged in. These
lines are two extensions of a panasonic PBX.

        Zap/1 = X100P <-- analog line --> extension
#237 PBX Panasonic
        Zap/2 = X100P <-- analog line --> extension
#245 PBX Panasonic

- 1 TDM20B with two analog telephones plugged in.

        Zap/3 = TDM20B port 1 <-------- Analog phone
        Zap/4 = TDM20B port 2 <-------- Analog phone

I must to verify the call transfer with consultation. 

For example, when an input call comes through X100P,
my Zap/3 extension rings. I pickup Zap/3 and I want to
transfer the call to Zap/4, but before to establish
the call between X100P and Zap/4 I need to request
Zap/4 for answering the call.

I have already searched along the mailing list.
It seems to be easy but I don't know how.
