Hello Colleagues I require your collaboration I have a SIPTrunk in IAX2 protocol between an Issabel V4 with Asterisk 16.7 and it is linked against a FreePBX with Asterisk 16.3 the problem that is being generated is that around a month and a half the link after being working correctly Between both exchanges and making calls OK, the IAX2 link falls and the only solution for it to be able to raise this link again is to eliminate the IAX2 trunk in both centrals and when they reconfigure the link, it goes up one.
The configuration I have is this in both control panels:
type = friend
qualify = yes
nat = yes
insecure = port, invite
host = 172.26.9.254
dtmf = rfc2833
disallow = all
directmedia = update
context = from-trunk
allow = ulaw, alaw, gsm
I look forward to your help colleagues in advance, thank you very much
