AWAITING FEEDBACK Unable to register trunk to vitelity hostname

[nelsonfirst]

Incredible PBX 13-12.2 for Scientific Linux 6.7.

System has been installed and working for months, registering to inbound41.vitelity.net. Now getting this error registering to that hostname;


ERROR[2785] netsock2.c: getaddrinfo("inbound41.vitelity.net", "(null)", ...): Temporary failure in name resolution

ERROR[2785] netsock2.c: getaddrinfo("inbound41.vitelity.net", "(null)", ...): Temporary failure in name resolution

I am able to register to Vitelity's IP so I was thinking DNS issue but the strange thing is I can ping, traceroute the same hostname fine. The weird thing is this is happening on two different servers within hours in different towns on different ISP's and different DNS servers. Any clues would be appreciated.

cat /etc/resolv.conf
what does it say in resolv.conf?

don't know who those nameservers are provided by, but you might try 8.8.8.8 (google) and 4.2.2.2 (Level 3) and see if you can get resolution.

@nelsonfirst You are clearly aware that those nameservers are located in <your.nelsonfirst.local> lan implying that your network has two (internet) nameservers running locally. You do not say how those nameservers are getting to connect with servers on the wwweb
- so - shouldn't there be at least a couple of internet dns nameservers configured in the list or somewhere, for resolution of any non local url.

I presume that you may be using systemd if so you will have configured /etc/dhcpcd.conf
something along the lines of see here

I have tried setting resolv.conf to google dns of 8.8.8.8 & changed it in /etc/sysconfig/network-scripts/ifcfg-eth0. But does not seem to fix asterisk.....remember I can still ping successfully from command line with all of these dns servers But Asterisk itself seems to have issue with name resolution. Here is a successful ping;


ping inbound41.vitelity.net

Then this is what I see in asterisk -rvvvvvvv

The warning says it is an invalid argument because the IPaddress and port is set to (null) so it seems to be going nowhere.

getaddrinfo("inbound41.vitelity.net", "(null)", ...): Temporary failure in name resolution

No idea why it doesn't resolve. Maybe there will be clues in the full log ???

A quick google brought up the following link:
