Just a little background: I am apart of a program that uses Asterisks, version 1.8.11, and they are worried about security vulnerabilities. To resolve the vulnerabilities, they’d like to upgrade to the most recent version (15) of Asterisks. Their current Asterisks has a modified chan_sip,c and it also has other custom channels (chan_*.c) added to it. There is also a module added to it that does some custom parsing of data and communication to another subsystem. I need some advice and expertise from folks that know more about Asterisks than me. Would you say an upgrade is feasible/doable within a reasonable amount of time?
Apologies for the vagueness, but I’m not sure what else to add to the question. If you think of something that can help add substance and understanding to the question, please don’t hesitate to respond.
Any advice would greatly be appreciated.
Please and thanks in advance.
