Consider 2 trunks configured like this:
#1: trunkprefix=8888 removeprefix=0 failover=trunk #2
#2: trunkprefix=8889 removeprefix=0 failover=-1/none

When dialing 0123456789 the call is presented to trunk #1 as it should be:
888812345678

If the call fails over each of the successive attempts will add the correct prefix, but not remove the desired digits:
88890123456789

Nice post stavros

Yesterday, we were having some issues cause the failover was not working correctly at all. If it's caused by the same bug, I will fix it for sure. Cause we had to go and manually change the trunk attached to each ratecard to bring the system back online.
