My asterisk are setting with simple configuration:

[general]
port = 2427
bindaddr = 192.168.1.254
disallow = all
allow = ulaw
allow = alaw
allow = g729

[192.168.1.154] ; mac address of cisco phone
context=from-internal
host=192.168.1.154
wcardep = *
line => a001

Asterisk have a simple extension:

exten => _6NNNNNN,1,Dial(MGCP/a001 at 192.168.1.154)

In the command line:

asterisk*CLI> mgcp audit endpoint a001 at 192.168.1.154

There are no dial tone in the MGCP phone. 
When I dial (from a zap) to MGCP phone, I listen the ring, and the MGCP Phone ring too, but when I pickup the MGCP Phone, there are no sound. The calling phone is ringing.

Do your any clue for this problem?

Thank in advance
