Hi Coral, My 10's of hours into the ATT void seemed to have paid off. I was packing up this morning to go home empty handed and decided to check the system a final time. SIP was registered! The ATT changes must have taken effect overnight. They turned off "DND error assist" and everything...

Yes I am

I believe this is what is happening: https://www.dnsleaktest.com/what-is-transparent-dns-proxy.html Not a lot I can do at the moment.

Hi again, No I have done this before but the ATT service at this site is being tricky. I have attached a Pcap from the internal pcap while I was turning the trunk on and off with 10-36. Thank you...

Here is a call I picked uphttps://files.engineering.com/getfile.aspx?folder=aff59518-de75-463c-9bb4-ee5224aad184&file=wireshark_home2Suites_call_answer.pcapng

Can you be a little more specific of what to look for on the wireshark? Do I want to see outgoing or incoming packets from the IPL? I am getting a lot of "who is .....241" http://192.168.1.241 is out IPL voip...

Thank you, working on that now

updated firewall settings. Proxy port was removed and still fully registered so that is a good thing. Still no audio on calls.https://files.engineering.com/getfile.aspx?folder=dd49165a-3a59-4b81-86ec-b0b9a662eabf&file=usg_settings_2.pdf

Its a bit of a back and forth as you can imagine with 5060 here, 5090 there. Im sure I am not fully complying with this, here are some examples: 84-14-06: 5090 10-29-04 5060 10-29-07 5060 I am making a list of IPs to whitelist, port forwarding and ports to open. If you have an =y rules to keep...

I was given 5090 by Nuso. Not sure. Not in other documentation but hard to argue with the carrier? -Noah

I am using a Ubiquity USG and am attempting to set it up correctly. I have added a screenshot. Here are my settings attached as a PDF. I think I am wrong on my settings about "internet in" and "internet out" for traffic rules. I got a 200ok for my registration but I am being told it is not a...

Yep, those do look right. I checked that SIP ALG is off. Calls are still no audio but I was able to set my caller ID. Thanks -Noah

Hi great news, after lots of effort, I was able to register with the carrier, I had to set a proxy Ip in 10-29. All 6 trucks are up and are staying registered. I cant make calls on truck 1, but on 2-6 I do get a call through to my cell phone with no voice and a caller-ID of 11111111111. Any...

Thank you, Nat is "used" and I did put my DNS addresses in 90-11-11. Can you expand a bit on the translation tables? It is default by the looks of it. -Noah

I am thinking my ATT router may be the issue. I is simply giving me an error message when the system is trying to DNS out. https://files.engineering.com/getfile.aspx?folder=4167c92f-74e2-4669-90bd-d8e0303e16ef&file=my_router_is_just_saying_when_the_DNS_is_trying_.png

Hello all, I am working on a SV9100 install and getting severally roadblocked by my network and SIP registration failing. Between ATT, NEC and Nuso the carrier, nothing is obvious. I have verified that ports are open, the firewall is open ect. I have 8 analog line cards and a single CP20, no...

Not out of the woods yet. The site I am at has lost track of the firewall and how to access it so I cannot take care of the issues via whitelist or blacklist. The two devices that popped up in wireshark cannot be found physically yet either, one may be an employs laptop network card. A new fire...

CoralTech, You are correct, a packet capture revealed multiple ARP probes attacking and confusing and locking everything up. Working now to identify and remove the sources. Thanks!

Hello all, I have a 300 user 9100 bridge system with two towers, netinked together. My system is working great, up until the moment it is not. My main symptom is the primary system, ID1 locks up randomly and pull the whole system down with it. ID1 then will not shut down with power removed and...
