THANK YOU SO SO MUCH!!! You've just saved my term paper. I just couldn't get to work Express Talk softphones, but Linphone and "sip:" trick saved me a whole lot of time and brain cells. Thanks again!!

This video is obviously old, but it was exactly what I'd be searching for. You saved my a lot of money and time. Thumbs up!

Thanks im working to install a new process plant, and I was about to recomend the use of regular intercoms, this is way more usable and more practical, thanks again !!!

Im I understanding you correctly. I can basically connect two GPX2000's to my Router and as long as I know each phones IP I can call each phone on my network?

Please advice can I add direct ip calling on speed dials

Hey great video, I have a few questions about voip calling doing what you've done here, I can't find any direct ip calling settings on cisco ip phones? Will this only work with grandstream phones? Not many resources online discussing this for cisco. Any help would be great, I've tried using linphone and calling the ip of said phone and it never rings threw. Thanks in advance.

Hey thanks alot, I will definitely investigate the link, what I'm trying to do is ensure that 1000's of Cisco ip phones have dail tone. It's easy to ping them and see that packets are indeed being sent and received. But it's apparently not good enough for the customer they need dail tone testing, I'm currently finding the fastest way to test them, as with all piece pay work time is of the essence, trying to use a raspi running freepbx has over complacaited the process. Any other advice or ideas are extremely welcome thanks!!

Thank you, I really appreciate your feed back :)

Hi, is it possible to use 2 voip CISCO CP-7821 as an intercom without a telephone line?

Well done - information in a snap - Thank You

Hello, perhaps you can help, we have a VOIP pbx at our office with VOIP phones, we are trying to have a "click to call" directly from web browser so we do not have to dial the numbers

Hi, I have a project that requires that I connect 300 VoIP phones to several blocks using fiber optics cable and cat 6 cable. Do I need a PBX to achieve this?

Thanks, such a useful feature in case we want to test if the phone itself is OK..

Nice Video. I found it very interesting that you can do that. I got 2 questions: 1. Can you dial with the ip address on a cisco phone? 2. What is the difference between an ip pbx and a sip proxy?

I have Fanvil x5 IP phone. I want to use as normal phone. Ca some one guide how can I use as normal analog phone

I have a Ip PBX Panasonic system can I use other ext to other country ?? And that's cal are free ??

Tried on Grandstream not working could you help

Usually you can just dial the last 3 digits and number sign.

So this feature can be done if you zero out the IP addresses on the SIP proxy and register. It uses the latter block of a LAN IP address to do peer to peer calling. However, this is great during a Post Zombie Apocalypse; however this also referred as "Direct IP Calling". From the simple point of view, this is how "ghost" calls exist on SIP sets. Worse; this is actually how voice spam; and bad boys can use this to scam callers if such sets are used in wide deployments. From my understanding, Direct IP Calling is strongly * not * recommended, which also means the Grandstreams, Aastra, Polycoms are the only ones that could do this. I think newer Cisco SIP and Avaya and other vendors have tried to turn away from this feature. It's cool and it should be only for the home as you see. Not to mention the regulated environment of office telephone systems these days.

VoIP.soft ware install need ??

Make video to show how to set up ip phone without pbx .. the ip set up in each phone

Good effort, dear

I'm sick of people who talk so fast that you can't understand the most important part of the video. Lynn Phone Lin Phone Lynne Phone Sin Phone I can't find any of them, and I have stopped looking permanently.
