ISA550 - VOICE(GE2) on WAN2(GE7) interrupted if WAN1(GE1) goes down

Even though Voice is routed (PBR - WAN weighted by link bandwidth) to WAN2 (with or without failover to WAN1, makes no difference), if WAN1 happens to fail when a call is active, it is interrupted, albeit for only about 5-10 seconds (the call is not dropped). It also occurs if WAN1 comes back online during a call.

I guess this is because the ISA is rebuilding routing tables, but is it possible to configure so traffic to WAN2 is not interrupted if WAN1 fails?

Env:

ISA 550 firmware 1.2.18/1.2.17

Weighted by Link Bandwidth

Traffic is distributed between two WAN links using ratio of bandwidth specified below

WAN1:          99

WAN2:          1

Link failover detection is specific DNS servers
