As per my current problem. 
SIPGATE CUSTOMER -> SIPGATE -> ASTERISK {WORKS}
<... at inbound-sipgate-584e;2> Playing 'conf-enteringno.gsm' (language
'en')
/PRESS 1234 AND READ BACK DETECTED WITHOUT ERROR/
-- Executing [123 at cc-test:6] SayDigits("... at inbound-sipgate-584e;2",
"1234") in new stack

BUT - PSTN -> SIPGATE is nogo:

PSTN -> SIPGATE -> ASTERISK {BROKEN}
<SIP/sipgate-dv-00000008> Playing 'conf-getconfno.gsm' (language 'en')
/MASH KEYS AS MANY TIMES AS YOU LIKE - NOTHING DETECTED/
