I have 6 sites with Asterisk versions :
1 at version 13.7.1
4 at version 13.11.2
1 at version 13.12.2
Originally these sites were serviced with Asterisk version 1.6 systems and phones. We replaced the systems and left the phones in place. The SIP trunk provider is the same for ALL the sites. All the routers are the same. The problem we are having is that on outgoing calls we are experiencing no audio. We get a No response to our crital packet error. I have read that version 13 has this issue occasionally and that downgrading to 11 fixes the issue. I need to resolve this issue quickyl, will going to 14 help?
