I'm experimenting with asterisk 13 and sipml5 on a cantos virtual machine, Everything is configured properly.
I use Firefox 38.0.1 to make calls from an extension to the other, and till last night everything worked just fine.
Now today when I start to call an extension and want to answer that call, firefox suddenly crashes.
Any help will be highly appreciated.
Finally I solved my issue with Google Chrome 43, I didn't want to use it but I had it coming.
