For some reason asterisk did not dial the number but the control came to the context that I defined in the call file as if the peer had answed the call. It works if I change the channel from DAHDI to a SIP channel like SIP/4567 or I dial DAHDI/1/xxxxxxxxxx from a SIP channel. I am using asterisk1.4.23.1. Is it a bug in this release?

Analog FXO ports are considered "answered" as soon as dialing is 
finished.  The telco does not provide a signal to the calling device to 
indicate the far end answered the phone.  This does not apply to PRI or 
FXS.  Virtually all SIP service providers use PRIs.  If the service 
provider used analog you would also experience this when dialing using SIP.
