Ok, I now see what you are asking
You are referring to the format:
Caller > callee
I would be happy for anyone to jump in here with an opinion, but I do not think that your number (as the called party) can be the callee. The format is intended to direct calls out on other trunks like so:
{>(1xxxxxxxxxx):sp1}
This would mean any calls matching 1xxxxxxxxxx incoming from any caller, would be sent out on sp1.
In another thread on scammers, I suggested an InboundCallRoute of:
{(?|x|xx|xxx|xxxx|xxxxx|xxxxxx|un@@.|anon@@.):},{ph}
This will ban calls with no Peer Number, any Peer Number less than seven digits, Peer Number "unknown" and Peer Number "anonymous".
It is more tedious to have to list the banned numbers, but I think it may be the only way. My suggested route was to suit my set up as I need to allow seven digit numbers. You may be able to modify it to your needs. Start by looking in Call History to see what the nuisance calls show up as in Peer Number.
