I am specifically excited to tell about new richer version of UCMA 2.0 SDKs, which we were working since last one year. Now developers are empowered to build number of middle tier scenarios like custom automatic call distribution, interactive voice response, gateway scenarios, enhanced presence based communications etc.  We do now have SIP based signaling protocol stack, media stack and speech engine containing speech recognition and speech synthesis.

 

In next few days I would be writing about SIP signaling pieces of UCMA sdk, at the high level you can see following features

- ServerPlatform with TLS connectivity and in-built connection management,

- Fully baked endpoint API, which supports trusted ApplicationEndpoint and regular UserEndpoint,

- Better Presence publication and subscribe APIs, which abstract previous SipSubscription class to LocalOwnerPresence and RemotePresence classes,

- ContactGroupServices class exposes Contact/Group management APIs ,

- Multiparty, multimodal Conversation model, which enables multi-modal, multi-party conversation,

- Conversation escalation, where simple 2 party call could be escalated to multiparty conference and add new madality in existing conversation,

- ConferenceManagementServices class exposes API to schedule, modify, schedule conference, 

- In built support for Audio (AudioVideoCall) and IM (InstantMessagingCall), all SDP negotiation is handled under the cover,

- In addition to number of How-to samples, a fully working sample for ACD (skill based automatic call distribution)

- ClientPlatform to simulate client scenarios for testing purposes

 

I am looking forward to write more details about these and waiting to see exciting scenarios built using UCMA.

]]> UC Managed API (UCMA) v1.0 beta available https://docs.microsoft.com/archive/blogs/adarshk/uc-managed-api-ucma-v1-0-beta-available Mon, 02 Apr 2007 14:58:00 GMT https://blogs.msdn.microsoft.com/adarshk/2007/04/02/uc-managed-api-ucma-v1-0-beta-available/ I was eagerly waiting since a long time to write about this exciting news, With the public annonucement of OCS 2007 beta, now we have a managed API known as UCMA is publicly available. Before coming out with official name UCMA, we were internally calling it as Ucp.net sdk. This SDK opens up the Sip signaling stack for managed application. As soon as it publishes on MSDN (expecting within a week or so), I will provide the download link and I will post more real scenarios and samples here.

Its a sip stack endpoint API, below is the list of some interesting features you will see in UCMA 1.0

a) Support for Sip Endpoint REGISTER to sip servers and SipPeerToPeerEndpoint,

b) Full SipSignalingSession to establish Sip dialog, it includes support for REDIRECT and REFER,

c) Utility classes for Sip header, Sip uri and SDP parsing,

d) Support for SIP SERVICE request, which is commonly used by OCS for publish operations,

e) Support for basic SIP Subscription dialog  and Notification with automatic refresh, 

f) Great scalability for middle tier application with MTLS server connection management,

In the coming weeks I will be posting simple code snippets and explain the usage scenarios for each of this feature.

]]> "Test driven development" - some practical experiences in API development https://docs.microsoft.com/archive/blogs/adarshk/test-driven-development-some-practical-experiences-in-api-development Mon, 05 Mar 2007 21:46:00 GMT https://blogs.msdn.microsoft.com/adarshk/2007/03/05/test-driven-development-some-practical-experiences-in-api-development/ Since last few years I was reading a lot of discussion about "extreme programing"  and "test driven development". I decided to explore and apply some of those principles in my own development and within my team. Here are some of the interesting things I would like to share. These experiences are based on a project for developing a public SDK.

Approach:

First thing I really did not try the hardcore methodology of test driven development. I took a little relaxed approach with relaxed restrictions.

My approach contains following category of pro-active and reactive actions.

a) Pro-active action was applied on all new functionality, here I did applied the rule that at minimum main line happy scenario code path must be included as an automated unit test and most common failure code path should be covered,

b) Second action is reactive approach, here when our test team reported any issue. Fix must include unit test and should also try to cover other related scenario.

In some sense this looks very relaxed compare to hardcore "test driven development" approach, but I found it is easy for adoption within the team and still contains lots of benefit in terms of time investments and returns.

Results from this approach:

Overall I was very encouraged with this approaqch and here are some of the fruits I found in applying this approach 

a) Overall quality of regular build is improved with almost no regression in mainline scenarios.

b) Unit tests included with bug fixes helped to cover more related scenarios in addition to identified bugs.

c) Test team is more happy; unit test code snippets works as live spec document for them and help them to start testing right away.

d) Very few complaints from test team about missing or outdated specs.

e) Test team is very active in finding corner cases, fault injection, stress, perf scenarios and helped to provide better coverage and repro, which definitely improve the overall quality in eraly product cycle.

e) Writing the unit test for happy line scenario help us to exercise our scenarios as a real API user customer. This helps us to find API naming and usabilty issues even before including the public API in product.

f) We did keep test code and product code in separate assemblies, this helped to improve overall debuggability of the code.

Overall I found the approach was very practical and beneficial for us, I will post more details and some quantitative data later.

]]> Communicator Web Access AJAX Service SDK Released!! https://docs.microsoft.com/archive/blogs/adarshk/communicator-web-access-ajax-service-sdk-released Thu, 06 Apr 2006 20:20:00 GMT https://blogs.msdn.microsoft.com/adarshk/2006/04/06/communicator-web-access-ajax-service-sdk-released/ If you are looking for adding cool instant messaging and presence functionality to your web applications or simple C# applications, try out Communicator Web Access AJAX Service SDK, it already includes the sample code to get started. I will also keep posting quick code snippets here.

 

Quick Info from the SDK:

Communicator Web Access AJAX Service is the application programming interface for Microsoft Office Communicator Web Access. Application developers can use it to create Communicator-compatible clients that allow users to manage and share presence information, to manage contacts and groups, to send and receive instant messages, and to search for users within an enterprise. Such clients can be a browser-based Web application (e.g., an ASP or ASP.NET application) or a standalone network application (e.g., a .NET executable). The client applications can be written in a wide range of programming languages including JavaScript, C#, Perl, C/C++, and the Visual Basic development system. Because the Communicator Web Access AJAX Service is based on the flexible AJAX programming model, the client applications are not limited to running on Microsoft Windows operating systems and can readily be deployed to desktop, laptop, or other devices.

]]> Office Communicator Web Access is RTM https://docs.microsoft.com/archive/blogs/adarshk/office-communicator-web-access-is-rtm Tue, 13 Dec 2005 16:35:00 GMT https://blogs.msdn.microsoft.com/adarshk/2005/12/13/office-communicator-web-access-is-rtm/ Finally the official RTM day for Communicator Web Access (CWA) is arrived, its pretty cool to watch the real time presence and IM to your contacts from web based application. For me it was very exciting to deliver my first RTC product in hands of the customer.

Its pretty cool application demonstrating the power of AJAX and it is 100% managed application build on .net frameworks 2.0. Ofcourse it also uses the power of my favourite System.Net classes of .net frameworks. UI is pretty much same as familiar office communicator 2005. It is useful for anyone working remotely or non windows machine.  For Microsoft people it is already deployed (check => https im dot microsoft dot com), I found it very useful for communication, when I am sitting at home and not connected to my office machine.

To get more information and FAQ you can read Microsoft Office Communicator Web Access Overview

If you are looking for download check the Microsoft download center - Communicator Web Access download

One comment I can not resist to mention about UI, it is so much similar to office communicator 2005 :) that one of my friend even asked "How did it launch the office communicator on my machine and would it work on a machine with no office communicator installed." Only later he realize that it is browser window not the office communicator application.
