How to reduce the incoming PSTN ring delay in Asterisk.

Edit /etc/asterisk/chan_dahdi.conf and change following lines under channels context.

[channels]
cidstart=ring
immediate=yes
faxdetect=no
usecallerid=no ; If you are not using caller id facility.

Install Network Card Solaris 10

First run ifocnfig -a to see all the network card attached to system which has ip address.

My NIC  is  “ Intel Corporation PRO/100 VE Network Connection” installed in  Intel Pentum D 64 bit PC.

1. Use the below command to see the connected NICs.

# /usr/X11/bin/scanpci

#prtconf -pv | less

2.Download the appropriate driver file(tar file) from the other system and copy it to the solaris machine.

If you are using USB, see the previous mount article on how to  mount  USB on solaris.

3.unzip the file if it is .gz(gunzip -d) and untar it (tar -xvf) .

4.Run the commands to compile and install the driver.

% cd /…/ife-x.x.x

% rm Makefile

% ln -s Makefile.amd64_gcc Makefile

% rm obj

% ln -s amd64  obj

% /usr/ccs/bin/make

% /usr/ccs/bin/make install

% modload obj/ife

% /usr/sbin/drvconfig -i iprb

% touch /reconfigure

See the /dev directory to see the newly installed device.

# ls /dev/ip*

/dev/ip        /dev/ipf       /dev/ipnat     /dev/ipscan    /dev/ipstate

/dev/ip6       /dev/ipl       /dev/iprb      /dev/ipsecah   /dev/ipsync

/dev/ipauth    /dev/iplookup  /dev/iprb0     /dev/ipsecesp

Here /dev/iprb0  is my NIC.

Then reboot the machine.

Run the below command to get the DHCP address.

#ifconfig iprb0 auto-dhcp

# ifconfig -a

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index  1

inet 127.0.0.1 netmask ff000000

iprb0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

inet 192.168.20.181 netmask ffffff00 broadcast 192.168.20.255

ether 0:19:d1:67:f7:cd

If you want to add static ip run the following command.

#sys-unconfig

Other usefull commands

update_drv -a -i  ‘pci8086,1094.8086.d605′ iprb

Files

/etc/defaultdomain       Set the default NIS domain name, if any, if it changed.

/etc/defaultrouter       Set the default router’s IP address, if it changed.

Not that the device used in mount command is “/dev/dsk/c4t0d0p0″ and not “/dev/rdsk/c4t0d0p0″

c4t0d0p1:c” here the “:c” means Windows C Drive like access.
