How To: Connect a Televantage 7.5 Phone System to Asterisk PBX through SIP Trunking

by Jon on July 14th, 2010

Recently I have been trying to integrate Asterisk 1.4 with a Vertical Televantage phone system to use some of Asterisk’s free features instead of paying for licenses on the Televantage system. It took me a while to get this working 100%, at first I had the sip signaling working back and forth without much of a problem but then there was no audio. So I started investigating and found that I needed to change some of my sip peers settings and voila that did the trick. Here are the sip peer settings and a few screenshots on how to configure the Televantage server to dial into the Asterisk server.

[televantage]
type=friend
trustrpid=yes
sendrpid=yes
context=default
canreinvite=no
host=192.168.1.252
disallow=all
allow=ulaw
allow=gsm

1. The first step on the Televantage box is to add a SIP Server, scroll down on the left and click sip servers, then right click on the right side of the screen and select new sip server.

sipserver1Give it a name and in the server field just put the ip address of your asterisk server.

2.  Click on the outbound caller id and you can set these setting up however you wish I chose to use the default caller id settings for the system.

3. And the last step is to add a route to dial over to the Asterisk server via the Dialing Services module. Just right click in there and chose new dialing service and then SIP-to-Centrex. I chose the digits to dial 8988 but you can make it whatever you want, then the digets that get passed to the Asterisk server are any digits after the 9899 that you send. So for example I setup a context on my Asterisk system to accept 22, so I dial 898822 from the Televantage phone system to contact the Asterisk server. Then in the SIP/PSTN gateway choose the name of the sip server you added in step 1.

4. All done now you can dial into your Asterisk server from a Televantage phone system for conferences, or any other Asterisk feature.

    Hi:

    I would like to do this on my servers, I followed your instuctions, but I can’t make it work.

    Do I have to create sip trunks to be able to make a sip call to asterisk?

    • What specifically are you trying to do? You will need to add asterisk as a sip server on your tele-vantage system to get this to work.

    I don’t know if you’re still around here. I’m currently running Televantage 7.0 with regular PRI. I like to add SIP service as backup so that when the PRI goes down, I can make call forwarding to the SIP.

    Currently I’m testing SIP (http://voip.ms) totally seperate from Televantage PBX. I created sub accounts under voip.ms and created Call queue on their portal, it works good. But I wonder if I can hook up this SIP service to my Televantage server. Is it possible? Voip.ms says, they provide 24 channels(trunks) for one DID I purchased.

    Where do I have to start from to hook up this SIP to televantage? It’s really hard to find about Televantage and any other forum.

    Currently we pay license and technical maintenance fee $4500 per year to outside vendor which I never call to get help. we have 1 PRI (23 trunks) and 50 extensions. Is this normal?

    I contacte Televantage, they say the license can be only kept by reseller and seem they are not fond of communicating with end user.

    • Hi Han,

      When I worked on our Televantage box it was version 7.5 which had some SIP licences included with it. I think the first thing you will need to find out is if your Televantage server has any SIP licences. If you do then yes you can do exactly what you are proposing with some networking and configuring on the Televantage server.

      Regards,

      Jon
