[Asterisk-Users] DTMF Question (misunderstood '*' button)

[Giovanni Barbis]

Hi all!

I'm experimenting a strange problem in my Asterisk PBX:
I've got an Asterisk pbx in the office: I dial an external number; the dialled 
number answers me correctly, but as soon as I press the '*' button (i.e. to 
navigate through the menus or to enter a password) my Asterisk box put me on 
hold.

(CLI transcription follows:
    -- Executing ChanIsAvail("SIP/222-23da", "Zap/g1&Zap/g2") in new stack
    -- Executing Cut("SIP/222-23da", "theChannel=AVAILCHAN||1") in new stack
    -- Executing NoOp("SIP/222-23da", "Zap/1") in new stack
    -- Executing Dial("SIP/222-23da", "Zap/1/34844503450||tTH") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called 1/34844503450
    -- Zap/1-1 is ringing
    -- Zap/1-1 answered SIP/222-23da
[Here I press the '*' button]
    -- Started music on hold, class 'default', on Zap/1-1
    -- Unable to find extension '' in context 'internal'
    -- Playing 'pbx-invalid' (language 'en')
    -- Stopped music on hold on Zap/1-1
    -- Hungup 'Zap/1-1'
  == Spawn extension (internal, 034844503450, 4) exited non-zero on 
'SIP/222-23da')


I think that Asterisk understands my postselection '*' DTMF tone like a 
command, not simply a tone to forward to the remote destination.

How can I solve the problem?

Tnx in advance
