I got the reconnecting message and warble tone about 15 seconds into my first test call ;) RC QoS shows 6.5% packet loss from server to client to match. Let's get Meraki to fix it. If you want to share your case number I can create another and reference it. I am a reseller of both Meraki and RingCentral so have some vested interest in solving this too.

BrandonS

So to recreate this I would have to be on an active call? I will give it a try. I suppose you have a reason for not using the new app? Maybe worth testing that one too.

BrandonS

I have an MR32 and MR33 where I am at. Before I try upgrading them 26 are you using the old RC phone app or the new one? iPhone? Can you share a screenshot of the error and of your SSID settings? For the new RC app (https://itunes.apple.com/us/app/ringcentral/id715886894?mt=8) I know a trick to turn on debug features and logs.

BrandonS

Which RingCentral Application are you seeing this on? I use RC and Meraki and have never seen this, but I am interested and might be able to help by trying to recreate some scenarios. I suppose you have isolated this to wireless by testing on wired connections also (unless it is the mobile app)?

I have similar internet at my home office with cable. Are the screenshots of jitter in table form from the RC tests? I don't see them in that format. I did run sos an capacity tests and they have good results even with IPS at the secure setting so it makes me think you are having an issue with upload. How many phones do you intend to deploy and how many simultaneous calls do you estimate? I would generally think with that upload speed maybe 10-15 simultaneous calls. Besides just disabling IPS you might also look at traffic shaping and see if you have the default QOS rule enabled. You could also consider setting per client limits and trying to throttle some clients or applications that are contributing to the uploads during the day.

This explains: https://meraki.cisco.com/trust#oob What happens if my network loses connectivity to the Cisco Meraki cloud? Because of the Cisco Meraki out of band architecture, most end users are not affected if Cisco Meraki wireless APs, switches or security appliances cannot communicate with Cisco Meraki cloud services (e.g., because of a temporary WAN failure): Users can access the local network (printers, file shares, etc.) If WAN connectivity is available, users can access the Internet Network policies (firewall rules, QoS, etc.) continue to be enforced Users can authenticate via 802.1X/RADIUS Wireless users can roam between access points Users can initiate and renew DHCP leases Established VPN tunnels continue to operate Local configuration tools are available (e.g., device IP configuration) While the Cisco Meraki cloud is unreachable, management, monitoring, and hosted services are temporarily unavailable: Configuration and diagnostic tools are unavailable Usage statistics are stored locally until the connection to the cloud is re-established, at which time they are pushed to the cloud Splash pages and related functionality are unavailable

I do have IPS enabled and with prevention/security. I was going to suggest a group policy for the RC phones, but it looks like you can't disable IPS/IDS in the group policies. How many clients and what bandwidth do you have? I wonder if you are pushing the limits of your MX? What ratio of desk and soft phones do you have? If all or most desk phones you may be able to use a voice VLAN and find a clever way to bypass the MX. I am going to run those test from my home with IPS/IDS on and off to see if I see a difference here.

And this is the current KB article the that includes current supernets, etc. https://success.ringcentral.com/articles/en_US/RC_Knowledge_Article/9233

These are the tools I would run with and without AMP and IDS enabled: https://www.ringcentral.com/support/qos.html https://www.ringcentral.com/support/capacity.html And this is their Meraki configuration guide: https://netstorage.ringcentral.com/guides/meraki_mx64.pdf

BrandonS

I sell and install both and have never had much of a problem. We use RingCentral and a MX at our own office and I use it at my home office too. Have you used their network test tools and have you tried disabling AMP and IDS to see if it even makes a difference?

BrandonS

I think the only way to see this is to hover your mouse over the connectivity bar and it will indicate the reason for loss of connection.

BrandonS

Is the problem that they can't establish VPN connection or they connect and then can't access resources? I have had the latter problem with Meraki NAT/DHCP mode due to 10.0.0.0/8 conflicting. Maybe you also have some subnet overlap between your guest network and the remote side?

@RossSRRoss wrote: Would configuring it automatically try and load balance to what is specified for each uplink or does it keep running everything out on WAN1? I guess they want to see if this would affect business if turned on during business hours. I am not used to doing any network configurations during bussines hours unless it was an emergency at my previous places of employments. All of my past companies had change control committees. And any network changes that could affect business was done after business hours. It should stay on WAN1 at default, but in the traffic shaping page you can choose to failover or load balance (and a few other options). Good on you for waiting to do changes after hours ;) I can't recall if it would affect WAN1 after you apply the change, but I feel like probably not.

BrandonS

Yes, you can. Login to the local configuration page and you will see the option there to change LAN4 to WAN2.

I can suggest https://papertrailapp.com as a cloud syslog server. It has a free tier and is also easy to create email, SMS and web hook alerts for anything you want.

There is a KB article and guide that should help too: https://documentation.meraki.com/zGeneral_Administration/Tools_and_Troubleshooting/VoIP_on_Cisco_Meraki%3A_F.A.Q._and_Troubleshooting_Tips Cisco Meraki VoIP Deployment Guide

I have the blog and some Google news alerts in my RSS feed for Meraki.

Am I the last to hear about MDP? I never knew this was a thing until I saw Wireshark 3.0 release announcement: https://www.securitynewspaper.com/2019/03/01/wireshark-3-is-launched-with-new-package-capture-driver/

BrandonS · ‎03-05-2019

Yes, there is a site survey mode: https://documentation.meraki.com/MR/WiFi_Basics_and_Best_Practices/Conducting_Site_Surveys_with_MR_Access_Points#Site_Survey_Mode I am pretty sure you want to design to not need more than one repeater hop. You lose 50% of potential bandwidth with each hop. If you need true wireless bridges for backhaul somewhere you will most likely want something not Meraki for those links because the MR can only "bridge" one VLAN. Good luck

BrandonS · ‎03-04-2019

Well, it will depend on the switch and probably also the router/firewall to manage the VLAN. Those could all be Meraki, but you are correct it can't be done with only a wireless access point since the AP does not act as a DHCP server (with the exception of guest mode)

BrandonS · ‎03-04-2019

Well, an SSID itself doesn't have a gateway assigned, but you will want to use bridged mode and then then add at least one VLAN tagged to a trunk port that your AP connect to. then you can tell SSID#1 to just use the native VLAN and SSID#2 to use the tagged VLAN. Your DHCP server will hand out the default gateway.

We don't want to segment the technical discussions unnecessarily, but for partner-specific business-y things, we'd be very open to creating a partner-only forum here on the community. @BrandonS - we'll be following up with you! (and don't start something on WebEx teams! We can do it here! That way, any kudos can count towards your MOTM scores and badges and the community team's engagement goals ;)) Great. I will refrain from soliciting members away from here :)

Good point. And the reason I don't think I will accept Bitcoin and don't understand how people use it for normal transactions since its value changes from moment to moment..
