asterisk users - Feb 2004 - How to Dial-out from USR Voice Modem

Hi 

after src/channels/chan_modem_aopen.c I made another channel driver called 
src/channels/chan_modem_usr2976.c. I made all the changes it required.

The driver loads fine, initializes modem etc:
Asterisk Dynamic Loader Starting:
?[chan_modem.so]?=>?(Generic?Voice?Modem?Driver)
??==?Loading?modem?driver?chan_modem_usr2976.so?=>?(U.S.?Robotics?56K?Voice
INT V5.19.1, OEM 2976 driver)
????--?Configured?modem?/dev/ttyS4?with?driver?USR2976?(3Com?Corp.?Model
U.S. Robotics 56K Voice Revision 5.19.1?7/15/99)



My problem is with asterisk usage. I know I am missing something I just
don't know what.

I made these changes to the /etc/*.conf files that installed after the
compilation of the source code:

modem.conf:
????????driver=usr2976
????????type=usr2976
????????device?=>?/dev/ttyS4

modules.conf:
????????load?=>?chan_modem.so


extensions.conf:
????????;TRUNK=Zap/g2???????????????????????????????????;?Trunk?interface
????????TRUNK=usr2976/ttyS4


I am not sure how to make a call to USR modem from PSTN ring the Console,
and I dont know how to dial out.

when typing dial 93102355 on CLI i get the following error
CLI> dial 93102355
Feb 11 00:03:43 WARNING[245776]: channel.c:1647 ast_request: No channel type
registered for 'usr2976'

channel of type 'usr2976'
??==?Everyone?is?busy?at?this?time

When I change the modem.conf to:
????????type=autodetect

I get the same response.
