Had to open 5060 inbound to get one providers trunk to signal inbound calls (either #STUN isn't working there or some #NAT issues), with predictable results..

Got older version of #fail2ban on this box to yeet all blighters trying to get in - by turning on security logging in /etc/asterisk/logfiles_custom.conf (add entry security_log => security), updating regexes in /etc/fail2ban/filter.d and pointing failt2ban jail to check /var/log/asterisk/security_log (main Asterisk log is in wrong format and I don't know enough regex to fix that)

Also registered a #Voipfone virtual PBX extension to use as an extra trunk (needs contact-user and from-user set in #PJSIP config)

The picture @alex drew a few months back sums up exactly what dealing with these #VOIP #trunks is like

#Asterisk #FreePBX

Finally got around to upgrading my company's #Asterisk box to #PJSIP last night! So glad I did.

We now have proper SNI support, better NAT traversal, better header management, #IPv6 support in progress, and perhaps most importantly, are now using something under active development, so security issues will be fixed sooner.

Please move away from chan_sip. It's been deprecated since 2019, and completely removed from Asterisk as of 2023.

#voip

A day of #telephones - reconfigured #FreePBX #trunks that link on-premises #PBX with #cloud PBX to use #PJSIP rather than chan_sip - hopefully they will stay registered more reliably, repaired handset of desktop #VOIP phone with broken RJ9 socket using another harvested from defective analogue set (not prettiest repair, and I had to check the wiring colours as they are *different* between original and new socket), but it works #Repair #Maintenance #Telecoms

After many hours of updating config files, I have finally retired my old #asterisk server, which has been doing sterling service since 2015. Asterisk is now running on #ubuntu rather than #centos and my BT landline number is about to transfer to @aaisp so I no longer need to cater for analogue lines or deal with #wanpipe and #dahdi! Converting everything from #sip to #pjsip was a major undertaking.

asterisk 21 will no longer ship with chan_sip !
