We were using a Balance 20 to provide failover for FIOS (primary) and Comcast (backup) service to our LAN. There are a few VOIP handsets on the network connecting to Jive. Verizon connection had been spotty, but Verizon said it’s no fault of theirs, so we bought a new Balance (One instead of 20) to see if that would fix anything. Same issue with FIOS not connecting, but now, the phones have refused to connect. Everything was configured exactly the same way. The only settings that I could see making a difference would be the SIP service passthrough, but it was set to Standard on the old one, which was the same as the default settings on the new one.
When we swapped the old router back in, the phones connected right away. I double-checked, and every setting is identical between the two. AP is disabled on the One.
Did anything change between the two firmwares? Firmware on the Balance 20 is 5.4.9, while the version on the One was 6.something (it’s offline at the moment, but it should have been the latest).
