Start a GetContactsByURI method call.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Request contacts and retrieve their attributes using URI addresses.</p> <p>The connection manager should record that these handles are in use by the client who invokes this method, and must not deallocate the handles until the client disconnects from the bus or calls the <tp:dbus-ref namespace="org.freedesktop.Telepathy">Connection.ReleaseHandles</tp:dbus-ref> method.</p>

`proxy` : | the TpProxy
`timeout_ms` : | the timeout in milliseconds, or -1 to use the default
`in_URIs` : | Used to pass an 'in' argument: The URI addresses to get contact handles for. Supported schemes can be found in <tp:dbus-ref namespace="org.freedesktop.Telepathy.Protocol.Interface.Addressing">AddressableURISchemes</tp:dbus-ref>.
`in_Interfaces` : | Used to pass an 'in' argument: <tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>A list of strings indicating which D-Bus interfaces the calling process is interested in. All supported attributes from these interfaces, whose values can be obtained without additional network activity, will be in the reply.</p> <p>Attributes from this interface and from <tp:dbus-ref>org.freedesktop.Telepathy.Connection</tp:dbus-ref> are always returned, and need not be requested explicitly.</p> <p>The behavior of this parameter is similar to the same parameter in <tp:dbus-ref namespace="org.freedesktop.Telepathy.Connection.Interface">Contacts.GetContactAttributes</tp:dbus-ref>.</p>
`callback` : | called when the method call succeeds or fails; may be `NULL` to make a "fire and forget" call with no reply tracking
`user_data` : | user-supplied data passed to the callback; must be `NULL` if `callback` is `NULL`
`destroy` : | called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be `NULL` if `callback` is `NULL`
`weak_object` : | If not `NULL`, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be `NULL` if `callback` is `NULL`
Returns : | a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.
