Hi list. I?ve been considering in the last few days witch prepaid solution I?m going to test into my asterisk environment. The main issue about it is that I could not find a solution to use into my already-installed-and-fine-tunned mysql db that can autenticate the user without using those long-and-anoying PIN numbers but just with the from/contact or even digest of the sip message. Do anybody has a clue to help me? Thanks in advance, Ricardo Poppi.
