I'm not familiar with those carriers.  Also note that carrier WiFi calling also has to be permitted by the carrier.  I've seen carriers that only allow WiFi calling from their own broadband customers. ... View more

Hmm, it should allow the call to come up - but I would expect it to drop if you try and roam (NAT state is not carried over between APs).   If you use a calling technology that includes monitoring (like Microsoft Teams) it should recover automatically on a roam event with a pause. ... View more

Have you got the port where the MX plugs into your switch configured for auto/auto, and have you also got the MX configured auto/auto?   This sounds like a classic duplex mis-match. ... View more

Huh?  You can put any IP address or subnet in a firewall rule, whether it exists on the MX or not. ... View more

If you don't buy an MS390 (and you should avoid them, buggy) you only have one licence option - Enterprise.  So that just got easier.   Your next choice is the licence duration.  Most companies go for 3 or 5 years.  5 gives you a better pricing deal.  Note that if the licence expires the switch will stop working.  You can of course renew the licence.   This datasheet lists all the models in a table and feature comparison. https://meraki.cisco.com/product-collateral/ms-family-datasheet/?file  ...

Best option, remove the loop.  Make one stack the core, and the other two just hang off the core.   Second best option, on your 3850's: spanning-tree mode mst       Also, configure one of your stacks to be the deliberate spanning-tree root by setting the priority rather than just allowing them to choose themselves.  That should be the core switch, refer best option above. ...

With Azure - that sounds risky.   I think I would do a side by side deployment.  Then move the site to site VPNs over to the new VMX.  Then when nothing was using the old one, delete it. ... View more

@Bruce is correct.   The issue mostly affects providers using SIP/UDP.  If you change to using SIP/TLS or SIP/TCP which has inbuilt connection monitoring methods it should start working properly. ... View more

As @ww says, start by checking the local status page to see what the switch things is going on.   I would leave the switch plugged in for at least an hour before getting worried.  Some of the initial firmware upgrades take a long time. ... View more

This is a classic Azure - and it is really painful when it does this.  Azure support will also not be able to help. <rant>It's moments like this I really hate Azure, and reminds me of why I mostly use AWS.</rant>   The fastest solution will be to redploy the VMX.  I promise you.  Don't waste your time trying to fix it or dealing with Azure support. ...

The problem is "POST" is considered an unsafe HTTP method by many libraries when following a redirect.  So the library automatically changes it to a GET (which is considered safe) and breaks things.   Try Googling something like "python requests follow POST redirect".  requests will have some flag or method you can use to override this behaviour.  I have run into it before, but it was so long ago I don't remember the solution.     The easier solution is to instead use the Cisco Meraki Python SDK and then you can forget about these kinds of issues. ...

I'm not confident that filter applies to the MX lineup.  I think it might only be for MS and MR.   Add the VLAN column to the client's list, and see if it displays a VLAN number for MX clients. ... View more

If you are doing a "don't fragment" ping then an 18000-byte ping should be dropped.  The MTU is typically 1500 bytes.   If you are doing a ping that allows packet fragmentation, then perhaps you are experiencing an MTU squeeze.  Perhaps you are using PPPoE and you're ISP only supports 1492 byte packets, and you need to lower your MTU. To test this idea, try reducing the MTU on your test machine to something like 1400 bytes: https://techamor.com/reducing-mtu-on-windows-10/  ... View more
