Hi everyone, we've got 2 WAN links to the internet at our main site. WAN 1 is a 200Mb link and WAN 2 is a 50Mb link. This is all configured through a Cisco Meraki MX and MS network.
All of the Cisco phones were migrated today from CUCM to Webex Calling, all the phones are on a vlan of 1200 and in Flow Preferences within SDWAN & Traffic Shaping on Meraki, i've setup internet traffic for that VLAN to go out through WAN 2, so source is 10.1.200.0/24 with any port and any destination. I've also setup a rule that says any traffic going in to that vlan goes through WAN 2 as well, i've also added additional rules for any UDP traffic with a source port of 9000-9009 and 5060-5070 will go through WAN 2 when it comes from any vlan.
The issue seems to be though that in Cisco Webex Calling management, when looking at the analytics, some of the public ip addresses for calls is the WAN1 public ip and some are WAN2 public ip. All the handsets are set up the exact same way so not sure why there is a difference. Anyone have any ideas why? We do have Webex Windows client on the client machines and all traffic that doesn't match the above rules go through WAN1.
The issues we're having is WAN1 tends to be saturated with client and server traffic and WAN2 was gotten purely to be for any VoIP and Webex traffic.
