RV180 and iPhone Wi-Fi Calling

[mallardnathan]

A Cisco RV180 Small Business Router powers my small business' network. I use an iPhone 5s on T-Mobile running iOS 8, so I have access to Wi-Fi Calling (my Wireless Access Point is an ASUS AC-1900 set only as a Wireless Access Point, not a router; the RV180 is the router/DHCP). 

Sometimes, when performing data intensive tasks on the network (downloading a large file for example), and I receive or make a call using my iPhone over Wi-Fi Calling, I'll notice my calling gets a little garbled or my call quality drops in and out.

Is there a way to set the QoS settings on the RV180 to prioritize Wi-Fi Calling to the iPhone when downloading large files? I know the MAC Address of the iPhone and have the IP address DHCP reserved in the RV180.

Thanks!

I talked with a Cisco support engineer, and here's what we've accomplished so far:

• We created three Custom Services: UDP 5060-5061, TCP 5060-5061, and UDP 40000-59999.
• We port forwarded the iPhone to each of the three above services, internal Ports 5060 and 40000.
• We enabled SIP ALG.
• We created a WAN QoS Profile marked High.
• We setup profile binding for the iPhone to each of the above three services.
• If we still have issues, we're going to attempt to create a second VLAN to route traffic from one of the SSID's on the Asus AC-1900 just for the iPhone itself so the iPhone has its own VLAN for voice traffic. Hopefully, we won't have to go there though.

No worries. By the way, if you have anything to chime in with on this, feel free to. I need to run more tests, but I'm hoping to make my Wi-Fi Calling audio clearer when doing hefty downloads.
