Hi all,

I'm at my wit's end here. I am setting up a SIP trunk on an IPO running 9.1 (provider is Flowroute). I have gotten everything to the point that the SIP invite gets to the IPO and the system will answer. However, it answers only probably 1/5th of the calls that come in on the DID. I have looked at everything and cannot figure this out. If there is a better way to set up a Flowroute trunk, let me know.

Here's a Monitor trace of a failed call.

I see you're using Network Topology LAN-1. Try deleting the STUN server address (entirely, don't leave it as 0.0.0.0), enter your public IP address, port 5060 for UDP and TCP, and set your firewall to Unknown, or Full Cone NAT, or Open Internet (depending on your firewall)

Also, which firewall are you using, have you disabled SIP ALG, is consistent NAT enabled?

Ok, I removed the STUN server. Here were the settings before. Note that Full Cone NAT was already selected automatically by running STUN earlier so I left it as that.

As for the firewall, I am using a Ubiquiti UDM Pro. I have disabled SIP ALG (SIP Conntrack module in Ubiqiti's interface). Here's a screenshot of the SIP ALG setting and the port forward for port 5060. I know the port forward is working since the traffic is making it to the IPO, and I can see it passing traffic in the syslog on the firewall.

Something I forgot to mention in the original post. Outgoing calls work great and the calls that do get answered by the system work perfectly. It's still not answering all calls at this point. What's strange is they will not work for a while, then randomly I will call and it will start working, all calls will work for a couple minutes, then they stop working again for a couple minutes. Rinse and repeat. This is the same behaviour that happened before.

Not sure if this will affect it but your LAN1 is set to dhcp.client.
Make lan1 static address.

Set it to Dial in and manually put in the Ipaddress.

I mean think about it , the ipo is like a PC.
If the lan address changes due to a server reboot you will lose connection.
That’s ok on a PC but not on a device which needs the same address all the time.

If you do a search you will see it’s advised to make it static.

The IPO is set in the firewall to always receive the same address through DHCP. This is how I do my servers and anything else I need a static address on. I don't think the IPO would be any different. If it is, that seems short sighted.
 
Upvote 0 Downvote
The important thing is that the IPO has a fixed IP address.
IPO engineers prefer to set that as static in the IPO so that it is not dependent on the IT infrastructure & can survive unintentional IT errors (fat finger moments making changes to the DHCP server or even the DHCP server failing completely).

Call us paranoid but we have all been bitten by data engineers wh think they know better than a mere telecomms eng.
(not saying that is you as you are clearly asking for help with thinks you are not sure on which is always a good sign)

Understandable - I have been bitten by many things similar in the past.

I’ve set the IPO to static at the same 10.10.42.2 address and it’s still not picking up most calls.

So after a good day's think, I noticed something on the failed calls. The SIP INVITE that Flowroute is sending is coming from multiple different IPs and they are different than the IP sending the INVITE on the working call...

In fact, looking into it further, in System Status I see that the trunk shows the resolved ITSP IP address as 34.226.36.33. That's the same IP as the working call came from, but the non-working calls came from IPs other than that (like 34.226.36.34, 34.210.91.112). There's no mention of 34.226.36.33 in the non-working invite, even in the VIA which is what the Association Method field is looking at.

If my understanding of how the IPO decides whether or not to respond to SIP INVITEs is correct, I'd bet that would do it! (If I am wrong here, someone please let me know!)

Now I guess the question is can I set up the trunk to answer to all of the IP addresses Flowroute is using, or convince Flowroute to only use one IP to route calls to the IPO. I guess the first part of that is a question for you guys and the second is a question for Flowroute if that isn't an option.

I have flowroute, never really any issue with it.
Change your Association Method to By Source IP
Change your call routing to Request URI

Just gave those settings a try and the issue is still happening. Again only on calls where the SIP traces show a sending IP different from the Resolved Address in System Status. For example, here's a screenshot of a trace of a failed call alongside System Status which shows the discrepancy I am talking about. Also note the resolved address has changed from earlier today when I posted my theory, at that point it ended in .33 and is now .32

I have another system at a client's office (also an IPO, running 9.1) using a SIP to PRI gateway since the client didn't have the requisite licenses for a direct SIP trunk, but did have PRI licenses (don't get me started...) and the gateway works perfectly with Flowroute. So I know the service works great, just I am missing something with the IPO configuration.

Does LAN-1 have a 0.0.0.0 / 0.0.0.0 default route? Or just a specific route to 34.226.36.33?
 
Upvote 0 Downvote
I assume that in your sip trunk the ITSP domain is set to the working IP address, this is why the others fail, there is no associated trunk for them to be processed on.

possible solutions (not 100% certain they are possible)
1 ) use a uri rather than IP address in the itsp Domain field
2 ) specify all the valid IP addresses.

in any case I hope this gives you enough info to start working on

LAN1 does have a default route to 0.0.0.0.
Screen_Shot_2022-08-25_at_1.38.07_PM_wzljta.png



The ITSP domain field is set to us-east-va.sip.flowroute.com. If you look at the original post each of the SIP Trunk configuration screens are shown there. I have DNS servers set both in the system settings and under the trunk settings.

Edit: I got in contact with Flowroute and they said that INVITES can come from any address within 34.226.36.32/28.

Ok I added the ITSP Proxy Address to be us-east-va.sip.flowroute.com, which is the same as the ITSP domain name.

Still getting the issue - it will pick up some calls but not others.
 
Upvote 0 Downvote
a quick nslookup shows this
Name: us-west-or.sip.flowroute.com
Address: 34.210.91.112

Name: us-east-va.sip.flowroute.com
Address: 34.226.36.34

so it is only a single IP address that is authorized via DNS and any other IP will be ignored
the range is 34.226.36.33 - 34.226.36.46

You can only add 4 addresses into the proxy list

Workaround
use a local DNS server and adjust the entry manually to have all the IP's added as valid options. Hoping they are not changing them any time soon

Downside
the system may connect to any of the other IP's to make outgoing calls and Flowroute may not allow that then you have to add the IP address as first entry into the proxy and then the name as secondary option

I like the DNS server plan....

I confirmed with Flowroute that they will accept outgoing calls at any of the addresses within 34.226.36.32/28 and they would provide months of notice if those IPs were to be changing. So I think that's my best option. I will see what I can do to get it done.

Alright. So I added the IP addresses to the DNS server on the network. I now get this as a result - looking better. I will test when I get back in on Monday and will go from there. Thanks again for all the help everyone.

So I tried calling the DID just to test. No dice. Fewer calls are being ignored for sure. But it’s still not working from some of the IPs. Any chance there’s a 4 IP limit on DNS lookups just the same as the 4 IP limit on the proxy address field? If so I’ll just make the requisite number of SIP trunks all with different subdomains pointing at only 4 of the SIP addresses, resolved by my internal DNS server.

Alright. I think I've got this fixed. Operating off of the hunch that the 4 IP address limit also exists for DNS resolution as it does for the Proxy Address field (and just isn't documented), I did the following:

First, I divided the incoming /28 into groups of 4 addresses. Then I created DNS entries for 1.sip.<mydomain>.com, 2.sip.<mydomain>.com, 3.sip.<mydomain.com>, and 4.sip.<mydomain>.com, resolving each of them to a different 4 addresses out of the 16 address pool.

Next I created 4 different SIP lines, each pointing to their respective <line number>.sip.<mydomain>.com as resolved by my DNS server. I added identical URIs to each of the trunks for the DIDs being used. I tested. Outgoing calls were now completely broken. Nothing happened at all, the phone would sit at Waiting For Line and eventually the trunk would fail out of service after enough failed attempts to place the call. But incoming calls seemingly worked fine.

So I placed us-east-va.sip.flowroute.com as the ITSP Proxy Address. This solved the outbound calls! Yay! But now I had another problem. The Resolved Address field in System Status read the same address for every one of the trunks, the address of us-east-va.sip.flowroute.com. So now incoming calls were being ignored again.

The solution to that? I changed the Association Method field to VIA header on resolved ITSP domain name. This solved the incoming calls being ignored while also leaving in place the ITSP proxy for outgoing calls.

All in all, everything works now! I haven't had a missed INVITE in about 3 days now. Hurrah!
