Hello,
From the documentation you posted, there is no mention about changing mobile base stations, just changing IMEI. If this is what you need, you can accept my proposal. If you need to change the base station programatically, I can't provide such functionality.
I'm experienced IT professional with more than 15 years in IT and telecommunications. Currently working for leading European telecommunications provider as Integration expert. I already have integrated CTI and CRM and have lot of experience in this field. The company was only mobile provider at the beginning and three years ago we started fixed line business. The solution is VOIP based and includes Asterisk. I have a lot of knowledge and experience setting up and administering Asterisk based VOIP systems and I'm also experienced in Java, PHP, MySQL and different programming and DB technologies.
I believe that you will be satisfied with my skills and quality of work.
Best regards,
Mihailo Marinkovic
