Asterisk module for voice recognition and inband tone detection in SIP calls

hi yes, i can do that for asterisk version 11+. please note, this task will be stohastic(no way have 100% evedience in current state), take upto 4 second time to change state(at least two ring required). Also it WILL use alot of CPU time. so on modern quad core cpu most likly maximum number of detection threads will be 10-20. suggested method - do fast fourier transform of stream, detect harmonic with level at least +40% and check if it is ring or not, after that compare with ring patterns. require at least 100 call recordings be provided to train algorithm.

I have experience in this field i used asterisk api (AGI) , i developped calling module for crm Let 's discuss about your project i repeat i have experience in this field thanks
