[SR-Users] Dispatcher alg:7 not working accordingly

[SamyGo]

Hi,

No, nothing at all. I haven't went too deep into debug logs but no internal
error was appearing. Everything was as calm as ever and I only get one
destination uri.

So maybe what I'm getting from your email is that , for this to work the
way I expect is to have more unique and random values in my hash_pvar to
get the required functionality.

Thanks once again,
BR
