Activa TSP was developed by ICR and given to the Community to facilitate the creation of telephony applications.
ICR is the first company to openly release a professional free software solution,
EVOLUTION Call Center.
EVOLUTION Call Center is available in Spanish. The English version is planned to be released in Q1 2010

Please drop a message in the forums and tell us how Activa for Asterisk worked for you.
We will be happy to hear from you what your configuration is like, if using SIP, IAX2, mISDN, ZAP or whatever, if using queues or if your MS Outlook or TAPI application is working well with open-source Activa.
We are interested into knowing what different configurations have been tested, what is missing and if there is something to fix (sure there is). If you let us know we may try to fix it.
