Has anyone used Microsoft's UCMA 2.0 SDK to connect to 3CX's free IP PBX to add voice capabilities to their application? If so, does it work? What I am trying to accomplish is having a windows form app running on 2 or more computers, and each person can connect to another person and carry on a voice conversation using their headset con...
Hi, I hope this would be my last question about this SIP subject, I have managed to overcome the last issue I had by asking a friend to help me from a remote computer, I'm able to connect between the computers, but here is the thing, according to all the examples I saw, the Callee should invoke the Ringing response, but in my applicatio...
I've looked at tropo, twilio and cloudvox, plus another bunch. Most of these services provide their own entry points (PSTN, sip, IM), which is cool. Unfortunately I already have a local PSTN number that is redirected to a local SIP account. For business, performance and cost reasons (I'm outside the US) I don't want to simply redirect ...
Hi, I have a small issue, I had my SIP client working, and I changed the structure of the code. I kept the creation process of the SIP objects as it was before, but now it does not work. I keep getting: java.lang.NullPointerException at gov.nist.javax.sip.SipProviderImpl.getNewClientTransaction(SipProviderImpl.java:285) and ther...
Hi, I've finished my SIP client and it works, as long as it comes to one on one, or x on x if the participants are defined in the beginning of the call. I would like to attach a caller or a callee in the middle of the call, I understand the main issue is in the media session joining implementation, but I do need to tell the new partici...
Hi, I've wrote a SIP UAC, and I've tried a few ways to detect and ignore repeating incoming messages from the UAS, but with every approach I tried, something went wrong, my problem is that all the messages that has to do with the same call has the same signature, and to compare all of the message text is too much, so I was wondering, w...
I have an IVR application which plays the prompts and records the user message and detects the DTMF. Currently the application is based on SS7 signaling and uses the PSTN based media boards for media play / record functionality. Now I have to move this application to IP based solution. For this, I need any open-source / low-cost solutio...
Hello. I need to implement the phone-to-phone funcionality in vb.net. I've got the sip-account information from webcalldirect, but have no clue how to initiate a phone-to-phone call? In their clientapp their is such a function, so i thought it must be possible to do the same in my own clientapp. Thanks in advance ...
Hi, I was looking into my code, and I wonder how would the SIP call flow would be best implemented /controlled using Jain-SIP, I have designed my SIP call flow to be handled entirely sightlessly by my own code, which I assume is not the right way to do things, so I wanted to see some implementation using the Jain-SIP dialog and transact...
Hey, I have deleted my previous question and post this updated: I have a an issue with my SIP UAC, once I received a ringing from the B2BUA on both the caller and callee, and the caller hangs up the call while the call is ringing (I send cancel request and receive "request terminated" on the caller side), the callee does not get any no...

I have several Snom VoIP phones in the office running off a virtual phone system in London somewhere. I've written a small PHP app that lets me control the phone remotely - all it does in the background is cURL into my handset's web interface and control it that way. However now I'd like my PHP app to know what other phones on the syst...
Hello all! I've been trying to figure out how to send a dial string to the asterisks server which should then handle a call to the phone with that extension. I know there are programs like X-Lite and such but I don't want to manually dial it. I want to pass a string instead. Is there any way? Any help or tip would be very much appreciat...
Hi, I want to build an iPhone app which has the option to make calls over SIP (VoIP) but at this moment I have no idea how to start. Does anyone have some information about this topic, or maybe a demo project which I can use to implement the SIP functionality? Thanks in advance! ...

Hey all! I'm currently able to send video from one soft phone to another but I'm not able to receive the video. So I'm only seeing the video that's being sent from the same phone sending it and not seeing the other phone's video. I know it's possible but I can't seem to figure out how to do this.

I saw a similar question from 1.5 years ago and I am hoping there is something better. I am looking for a totally managed C# implementation because I need it for the .NET Microframework, so I can't have .NET wrappers around C code. Has anyone run into a good C# implementation of the SIP protocol. I should not that I don't care about ...
