Calling Speech Server application from a hardware phone via PBXNSIP

Recommended Posts

Hello everybody,

 

I tried hard to get the following setup to work:

I have Speech Server application, where I can successfully connect from softphone (X-Lite client), which is connected to PBXNSIP. Now I like to phone from a hardware telephone. So I sign an account by Sipgate and registered it as a "SIP registration" trunk on my PBXNSIP system. Furthermore, I created an extension with the SIP-ID of Sipgate, that the incomming call has an trunk as "start point". In the Dial plan setup I routed the SIP-ID to the number of my Speech Server application, but everything I got until now is the mailbox (which is now disabled) and that the service is temporarily not available. So I think it should be something with the routing. I thought the configuration should be quite similar to that one of my softphone.

 

Here I have log snippets of both connections:

 

1. from the softphone:

============================================================

 

At last, I thought it has to something with the country code, because the Sipgate phone number comes along with the full country prefix, but I also add that to my dial plan. As you can see in the last log above I tried different routing, without any positive result. A bad side effect is after one call via the Sipgate SIP gateway the registration get and I have to reboot my system.

 

 

Thanks a lot for any help.

Hi guys,

 

I found the solution. I forwarded the call to 0814@[iP of my SpeechServer];transport=tcp. This construct isn't good for PBXNSIP in that field (as you maybe can see the: after "redirect to" in the log above is nothing before the system begins to check agains the dial plan). So I changed it just to 0814 (the number of my Speech Server application, but it this it not really relevant, because you have to add this again in your dial plan). Now it like to validate against +49814 (it adds automatically the country prefix). So you have to add it again to the dial plan and for the replacement I took now 0814 and it connects to my Speech Server application. Unfortunatelly it do not reconizes my voice input - maybe my telephone is so bad or something else.

 

Hope that will maybe help other ones.

 

Cheers zazi

Hi zazi, :(

 

what kind of phone are you using? What about an outgoing call from Speech Server to this phone?

Hi Jan,

 

through the Sipgate VoIP provider we connected our system to a real telephone number so you can use every kind of telephone or landline. That was a prior design goal of our application. Of course, you can also use a softphone client (in ways: 1. you call directly the delegated telephone number 2. you register the softphone client directly at the ip-pbx. The outgoing call should go over the Message Queuing system, which is related to the hosted speech application. And then know way over the system: the ip-pbx delegated it to the sipgate phone number and the initiate the real call to a real number. Unfortunatelly, this is currently not implemented in our system. We are just sending SMS outside, but therefore we use directly the Webservice from Sipgate.

 

Cheers zazi

Hello again,

 

now we got also the outbound call running. Here is a short description how to it (please ask for a detail one, if necessary):

 

1. set the proxy at the makeCall activity to your SIP peer of your pbx(nsip)

2. create an account with the specified name of your calling party (from the makeCall activity)

3. route the outbound call to your outbound proxy (I used here my sipgate account)

- it runs here as "Outbound Proxy"

- maybe also important to set up the port of the outbound server

 

Cheers zazi

 

PS: I'm still running version 3.0.1.3023 (because I've read about the problems with P-Asserted-Identify)

Hi,

 

I don't know really what do you mean with "inband DTMF" (it is just my first VUI during my studies). If it is related to the usage of DTMF, then my experience is that DTMF works for inbound calls. For outbound calls it is currently not implemented (so can't test it yet), but we've planned to link the main part of the workflow of our inbound VUI to our outbound VUI.

Generally, our VUI is designed for natural language queries/ communication. So DTMF is just a helping component in the case that the user isn't able to do a natural language query that matches.

 

Cheers zazi
