> When asterisk generates the RLMI part of NOTIFY request, the asterisk uses the local contact uri instead of the URI to which the SUBSCRIBE request is sent.
> Because of this mismatch some IP phones (for example Cisco 5XX) ignore this list.
> According
> https://datatracker.ietf.org/doc/html/rfc4662#section-5.2
>    The first mandatory <list> attribute is "uri", which contains the uri
>    that corresponds to the list.  Typically, this is the URI to which
>    the SUBSCRIBE request was sent.
> https://datatracker.ietf.org/doc/html/rfc4662#section-5.3
>    The "uri" attribute identifies the resource to which the <resource>
>    element corresponds.  Typically, this will be a SIP URI that, if
>    subscribed to, would return the state of the resource.
> For example if the SUBSCRIBE request is sent to
> sip:rls_1004 at asterisk.company.com
> the asterisk generates the next RLMI
