In our home network we have a Sprint Airave which has historically been required to improve CDMA cell signal, and a recently-installed Obi202 with two phone lines (RingTo, Google Voice) and Anveo E911 service.
The installation guide for the Sprint Airave insists that it should be placed between the cable modem (SB6141) and router (Sonicwall TZ170), but I think that this configuration interferes with network performance and Obi202 registration and voice traffic. I find that the Airave works better behind the main router.
I am currently experimenting with isolating VOIP traffic on the Sonicwall's OPT port, and placing the Airave behind the Obi202 (on its LAN port) and administering bandwidth management, access, and QoS rules for both VOIP devices through the Sonicwall's firmware.
1) Has anyone configured these two devices this way?
2) Does anyone have a guide for defining an appropriate access rule for the Sonicwall enhanced o/s to administer this configuration?
3) How should the internal router in the Obi202 be configured for this arrangement?
Thanks for any help.
