More than 2 years ago, I made some attempts to use DVG-6004S efficiently with Asterisk (the first comment on this post is mine). Now I’m back to say that in the last 3 months I’m using DVG with a firmware upgrade togueter with 3CX pbx software. I’ve been able to configure it as a trunk with all the benefits included, like using all 4 FXO ports individually on my dialplan. Also CID is being properly delivered to the SIP clients. Maybe you should give a new try to DVG-6004S / Asterisk with the new firmware!

thanks a lot~ I have registered the DVG-6004S as a sip user in asterisk server and also I typed the command: sip show peers, I can see the DVG-6004S as a sip user in the server also I can make phone call from PSTN network to IP network. So from above all, I think I have registered the DVG-6004S successfully in the asterisk server. But I still can not make the phone call from IP network to PSTN network. Do you think it is something wrong with extension.conf file? We added your command: exten = s,1,Dial(SIP/701,20,gtTwWmD(ww${ARG1:1})) in extension.conf, but still can not. Could you please figure out the problems for us?

There is no need to configure zapata.conf as zaptel cards are not used.

Make sure you have DVG-6004S registered as client to Asterisk. You can use Asterisk command prompt to check that this is done correctly. Then it should work for outgoing as per my description above.

I am sorry that I may not be able to help further because I had DVG-6004S on loan. I have since returned it.

Thanks for your reply first. Do you think I should make some change in mgcp.conf and zapata.conf both or just configure sip.conf and extension.conf. Because I still can not make phone calls to pstn network by following your explainations.

It is possible to use DVG-6004S as a SIP trunk and I have done it before but unfortunately I am unable to replicate the same settings again. Will post again if I get success.

I don’t think you can use DVG-6004S as a SIP trunk. It has to be a SIP client to Asterisk. So, it is best to use it the way as I described.

As for the CID of incoming calls, I am sorry to say I have no success. This despite seeking much help from D-Link. They said it is possible, gave me some configurations that just do not work.

Congratulations for the article! The information you wrote is very difficult to find anywhere else on the net.

Have you been able to register DVG-6004S as a SIP Trunk on Asterisk? If not, I’m going to use the way you described on this article, but will I receive the CID of incoming PSTN calls on the softphone?
