SRP521W 3G failover with Option iCon322 not working

Summary:

Using a Option iCON322 modem the 3G backup connection is not connecting after removing Ethernet WAN. The exact same configuration (using the same 3G SIM) is working using a Sierra Wireless Compass 885 modem.

Setup:

- all factory default expect:

-- 3G Modem config

-- Failover & Recovery Validation Custom address

- Main WAN via a Cablemodem connection (DHCP)

- SRP521W FW 1.01.24 (003) HW 3.0.0

- Option iCON322 FW 4.4.0

- 3G provider: Orange Switzerland

Testprocedure:

- Configure the SRP

- Reboot SRP without Ethernet WAN connection

- The 3G backup link connects as expected

- Plug in Ethernet WAN

- Fallback to Ethernet WAN as expected

- Disconnect Ethernet WAN

- The 3G connection no longer connects, tries to connect but always fails

(exact same procedure using a Sierra Wireless Compass 885 3G modem does work ok)

Log attached

Config attached

Any feedback?

Thx
