[SR-Users] Problem implementing usrloc via dmq

[Charles Chance]

Hi,

Glad you solved it - omitting the call to dmq_handle_message() appears to
be a common mistake. I may try to make it clearer in the docs that things
will not work as expected if this is not included.

As for the dialog/dmq integration, I've not had a chance to test it myself.
I will try to take a look later this week!

Cheers,

Charles
