hi,

I setup asterisk with libss7. I using E1 card, and 5ESS switch, when trying voicemail no audio while server play greeting files.

-- <DAHDI/25-1> Playing 'vm-theperson.gsm' (language 'en')
-- <DAHDI/22-1> Playing 'digits/9.gsm' (language 'en')
-- <DAHDI/24-1> Playing 'digits/1.gsm' (language 'en')
-- <DAHDI/23-1> Playing 'digits/0.gsm' (language 'en')
-- <DAHDI/22-1> Playing 'digits/9.gsm' (language 'en')
-- <DAHDI/24-1> Playing 'digits/3.gsm' (language 'en')
-- <DAHDI/23-1> Playing 'digits/8.gsm' (language 'en')

when i try voicemail with x-lite, audio normal.
I try change cicbeginswith to 0 or 2 (default 1), but no luck.
