[Asterisk-Users] Flash call transfer problem

[Andrea Frigo]

Hi,
    I have some problems transfering call from phone to phone with my Asterisk. When I dial Flash I can hear for half a second the dial tone, but it stops suddenly. The other phone hear the on hold music and pressing flash key another time I get back to the previous channel.
On the asterisk consolle seems to be all ok, this is whant I can read:

asterisk1*CLI>
    -- Swapping 0 for 1 on aaln/3 at Monforte_Euripide_9
    -- MGCP Muting 0 on aaln/3 at Monforte_Euripide_9
    -- Started music on hold, class 'default', on channel 'SIP/024390239-1c04'
    -- MGCP mgcp_new(MGCP/aaln/3 at Monforte_Euripide_9-1) created in state: Down
asterisk1*CLI>
    -- Swapping 1 for 0 on aaln/3 at Monforte_Euripide_9
    -- Stopped music on hold on SIP/024390239-1c04
asterisk1*CLI>

If I enamble MGCP debug I can read this when the dial tone stop:
