1 because asterisk event subsystem is nightmare 4/27/2013 12:39 AM

2 I recently tried to switch our most recent project from Asterisk to FreeSWITCH but until I get a 4/19/2013 6:29 PM chance to look at it again, this move remains an experiment that we have yet to deploy into production. Asterisk was not performing adequately and while FreeSWITCH was also less than stellar, it was better. I had actually wanted to use Adhearsion with FreeSWITCH from the start as I had long felt that Asterisk is marred by its legacy but my company preferred to stick to what they knew.

3 Asterisk was note delivering the stability we needed and some advanced functionality is flat out 4/19/2013 11:13 AM impossible.

4 Asterisk was making the app unstable but now on Freeswitch features are missing .... 4/19/2013 5:51 AM

5 Increased usability and maintenance along with getting access to new features like 4/18/2013 7:37 PM Prism/FreeSwitch support and the centralized configuration changes in Adhearsion 2

6 Asterisk was hindering the growth of our platform due to its inherent limitations. We need a more 4/18/2013 7:32 PM robust development environment and a more engaged community to help us add features to the core telephony engine.

1 Dial plan and application logic is much easier to program in AHN than asterisk. And better 4/25/2013 3:33 PM integration with webserver and database using AHN

2 Reduced license fees. 4/23/2013 7:54 PM

3 Asterisk to Ahn and PHP Scripts to Ahn 4/20/2013 11:12 AM

4 On asterisk from Perl-AGI to adhearsion. It was easier to maintain adhearsion code than to maintain 4/20/2013 3:57 AM old code.

5 Our app was on Tropo and it wasn't functioning the way we needed. 4/20/2013 1:57 AM

6 I have not done a straight migration as yet but I anticipate that our recent project will slowly start to 4/19/2013 6:29 PM inherit features from one of our long-standing core projects based on Asterisk and Perl, and eventually supersede it. The Perl code is poorly structured, massively duplicated, and a total nightmare to maintain. I look forward to getting rid of it. :-)

7 Twilio to adhearsion because of our revenue model 4/19/2013 2:21 PM

8 I migrated my first Adhearsion app from the Asterisk dialplan to better manage complexity. 4/19/2013 11:13 AM

9 1) project scope grew too large for the Asterisk Dialplan Language to be easily manageable, so it 4/19/2013 10:28 AM was migrated to AHN 2) AHN crashed constantly on the customer platform, and so we abandoned it at the beta stage of deployment and used something else.

10 From Telegraph to Adhearsion. We need a better solution. 4/19/2013 12:25 AM

11 We've migrated a lot of old Asterisk dialplan applications, and there were two main reasons: 1) 4/18/2013 7:32 PM Dialplan is convoluted and impossible to read. Everybody knows this but it keeps a lot of people employed. 2) We wanted to get access to much more advanced functionality - lots of database calls, web-interaction, and the whole ecosystem of gems. The amount of functionality provided by the dialplan was insufficient once companies moved behind simple "look this up in a database"

12 We had problems with asterisk. 4/18/2013 7:16 PM

9 Using Perl may have been quicker for an experienced coder but only because Ruby encourages 4/19/2013 6:34 PM you to design and test more elegantly.

4 I was unable to state earlier that we're seriously considering JRuby. And please don't be so 4/19/2013 6:58 PM dismissive of ActiveRecord and embedding it within Adhearsion. Whether this can be considered a clean approach or not is quite subjective and I think diligent use of with_connection works well enough for low traffic scenarios. For more intensive situations, I am optimistic that Rails 4 will solve the remaining issues. Please read http://bibwild.wordpress.com/2012/09/21/state-of-activerecord- and-concurrency-another-update.
