asterisk users - Mar 2003 - Sound card and other warning messages

Greetings Asterisk users.

When I launch Asterisk, I get the following

1. The warning messages listed above, should I be concerned?
I tested the sound card, by entering the command "dial", it plays the
Asterisk greeting message on the speakers.

2. Should I replace the sound card with a different one.  Currently, it's a
ES1370. (Ensoniq AudioPCI) 

3. After reading multiple docs, FAQ and mailing list archives, I am unable
to find out purpose of the sound card?  Is it used to play music, while on
hold?  Telephony PBX's usually don't have a sound card in them.

4. The WARNING - chan_iax2.c, I think, this is a configuration problem
(IAX), from the default files. That I have not gotten to yet.

My current test configuration:

Asterisk Server:
Pentium II 300 mhz
512 meg
Audio PCI
X100P - wcfxo
Intel Ethernet 10/100
Redhat 8.0

Clients:
(1) PSTN
(2) 7960
(1) ATA -186
(1) Messenger 4.7 (Soft phone)

As a NEWBIE in telephony services, I'll keep hacking away at this!!
Interesting stuff!!  Data person by trade.
Most of the topics in mailing-list are still way up my head, but I find them
very interesting.

BTW, Excellent start on "The Asterisk Handbook" version 2!  Helped me
with a
lot of other questions.

Thanks to all for the help.

It means only that you have some cheap sound card. If it works for you
that's fine.

If you don't want this messages put
noload => chan_oss.so
in /etc/asterisk/modules.conf

This channel driver is under developement. Also it reads the config files
of chan_zap.c so you shouldn't bother about that.

If it works for you => you don't have to.

You don't need sound card in your PBX. It may be used as another extension
(read: another "phone")

THis channel driver does not use "port" keyword.
