Re: [asterisk-users] Local calls not possible when Internet connection down
Hello, I confirm server and phones are on the same subnet and the phones are able to resolve local domain also when internet connection os down. It seems to be the asterisk bug I referenced before. There seems to be some bolcking resolver in it. I do not use database related to asterisk. This should be related to the srv record resolving. It seems quite random time to trigger the issue. When inspecting logs after internet problems started the issue appeared in one hour and several minutes. After restart of the asterisk it reappeared in less than half an hour. When trying to reproduce I was not able to reproduce for one hour and a half. So I decided to configure srv_lookups=no. I hope the issue is workarounded now. But I think asterisk should be fixed. It should successfully start when the VoIP providers sip server is not reachable, should recover after it becomes available. And should work locally when it stops to be responding. The tweak of creating /etc/hosts entry for the sip server and disabling srv lookups should not be needed. I hope sometimes theese issues will be addressed.

Re: [asterisk-users] Local calls not possible when Internet connection down
Are the phones and the server in the same subnet? You might making note of the IPs and just simply try pinging everything with the uplink disconnected. Also, if you are using domain names for registration, it is possible a dns server must be reachable. If you are using database for any of your call processing, an unreachable dns server can also be the cause of trouble. For some reason, even if you are using IP addressing, Mysql will try to resolve a connection and can hang (there is a mysql parameter to not resolve addresses).

Hello, it did not seem the call hung. It seemed it never started. There was no dialplan execution on the asterisk side. It looked like phones were unregistered. Same shows the log posted previously.

Re: [asterisk-users] Local calls not possible when Internet connection down
Marek, See if calls hang in the system if you encounter another outage core show channels ...if so, core set verbose 3 and see what instructions subsequent calls hang on.

Re: [asterisk-users] Local calls not possible when Internet connection down
Hello Joshua, thanks for suggestion. I just found out the same solution several minutes ago. I also obtained the maintenance window, so I diasbled outgoing DNS and SIP. But I was not successful reproducing the bad state. So I ceased futher debugging attempts and set srv_lookups to no. We will see once the next massive internet outage out of my control happens, whether it helped. Thanks again Marek --- Original Message --- On Tuesday, November 7th, 2023 at 16:28, Joshua C.

Re: [asterisk-users] Local calls not possible when Internet connection down
Hello, well I do not ask those who only guess, but those who know what is asterisk expected to do when internet connectivity goes down. I did not had a chance to make internet not to work yet, since it is needed. But inspecting dns logs I found out that there started to be resolving for _sip._tcp and _sip._udp records for the provider's server. So apparently making hosts record make asterisk happy when everything works, but when there is a communication problem then it falls back to searching for srv records. At least it seems to be so for now. Moreover I found out this old thread: https://community.freepbx.org/t/asterisk-become-mad-when-a-dns-problem-occur/4755/10 So the problem seems to be still present. So if asterisk is not able to resolve using it's dns resolver it breaks also local communication which is complete non-sense. I am thinking of two possible workarounds: 1. If thre is a possibility to convince asterisk not to fallback to searching for srv records, it would be ideal. Is somebody aware of such options in pjsip? 2. If the first workaround is not feasible I can create rpz records for provider's A and SRV records. When I will be able to shutdown internet or at least outbound DNS, I will try to make sure my findings are correct using tcpdump.

Re: [asterisk-users] Local calls not possible when Internet connection down
Hello, you are probably right. It should somehow be related to DNS. I just found out this in the storm of previous messages: WARNING[13945] taskprocessor.c: The 'dns_system_resolver_tp' task processor queue reached 500 scheduled tasks. But I am not sure why this is happening. I have sip providers hostname in /etc/hosts file to prevent such situations. Should I reconfigure it not to use hosts file but rather some RPZ on DNS server? Does asterisk ignore hosts file? Or does it try to do some srv lookups? But in either case, why does this influence local calls? Local domain should really be resolvable.

Re: [asterisk-users] Local calls not possible when Internet connection down
Hello, sure I have local DNS server and public resolving should not be needed for phone registrations. Running pjsip show endpojnt show the endpoints as not in use. When looking into logs I see only res_pjsip_outbound_registration.c: No response received from sip provider. Nothing else. In phone log I see: CC_eventProc(event=63(CC_EV_SIG_REGISTER_FAILED), lid=0, par=0, par2=(nil)) The phone is Cisco SPA525G2. Thanks.

Elements needed: run a local named, vs configuring resolver to your ISP for names needed in the LAN, ensure they are answered locally without needing any non-local DNS records. For me this is "foo.local" being in a policy zone to provide the LAN address of the host, as the WAN address goes away and changes Consider if you want to just put LAN IP addresses in your config actually turn off the WAN and test when that works, pull the cable to the ONT from the router, or equivalent, to simulate failure vs just deconniguring it and test again -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?

Re: [asterisk-users] Local calls not possible when Internet connection down
It looks like all phones get unregistered, but I am not aware of the cause. Why are get not registered when there is a connectivity between them and asterisk?

[asterisk-users] Local calls not possible when Internet connection down
Hello, I just realized that when my Internet connection goes down and I loose connectivity to VoIP SIP provider I loose ability to make local calls after some time. When I restart asterisk, I am able to make local calls for some time, but it then suddenly stops working again. I am using pjsip stack. What could be the cause of this?
