SIP Monitoring/Capturing System (VoIP)

I'm currently a Network Engineer in a ISP, and have been given the task to implement a VoIP SIP packets capturing and monitoring system. I've installed HOMER and decided to go with port mirroring on a switch port where these VoIP packets traverse to our clients.

My main question here is: What do you guys think is the best solution for this? HOMER seems pretty legit although a bit resource intensive. Which is the best Capture Agent? I can see there are many options out there: CaptAgent, Kamailio, HEPify, etc...

Scalability and availability-wise I do see an advantage in capturing/monitoring these files to the cloud, although this does imply high costs depending on the size of these logs.
