I have naive question. I do not have any hardware on my asterisk host. All I have are either SIP trunk for DID or hardware ATA which bridges the asterisk to PSTN. Do I need Dahdi install? Do i have ztdummy for timing issue? I encounter problem in this when I try to install Dahdi latest but I found it is not running, Instead it runs when service starts but I can't find its status when I type in service dahdi status.<br>
<br>I am using Asterisk 1.8.7 on centos 5.7 32 bit.<br><br>CK<br>
