Hi greetings;
I can handle your project and can solve the bug’s easly
We use to make a lot of sip protocol, billing integrations and routing management in servers made on asterisk, and other open source.
We have already implemented few changes to solve call drop and voice quality issue, in our previous tasks so it’s like you can handover to a right guy.
We managed 3000 ports to 20thousnd port setup for easy dial and ivr companies.
Let’s proceed with NDA and get to work soon!
Thanks :)
Mihir
