Outgoing calls - unable to create channel of type dahdi

Asterisk Asterisk Support

Dear List,

we are facing the problem, when we try to dial out a number from my sip softphone. Also could not receive any incoming calls

error:
unable to create channel of type dahdi

Asterisk - Version : Asterisk - 1.6.1
Dahdi - Version : 2.2-rc1

But, I am not facing any problem with Asterisknow 1.2 version of Installation. I could make calls / answer calls without any problem

I had given below the config file details,

/etc/dahdi/system.conf

bchan = 1-15,17-31

but, the FUN here is, that we could make calls happily by call files at /var/spool/asterisk/outgoing/

PLEASE GUIDE US TO RESOLVE THE PROBLEM

Dear Ian,

thanks for your input

I tried as given in your link. But no results

FYI, we could make outgoing calls when calls are placed in spool folder

at the same time, we could not even receive any calls through this e1 line as well as make any calls from softphone

But the same system with different hard disk installed with AsteriskNow 1.2 could do perfectly with the same hardware and e1 line (both incoming and outgoing is fine)

As a newbie, i kindly request you to check my system.conf, chan_dahdi.conf and extensions.conf

Am is missing any thing in these or apart from these files

thanks / sithi
