<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt">I am trying to get DMQ working for presence/dialog notifications. Presence works fine locally on the same SBC. The DMQ part itself is also working fine and I can see that the entries in presentity
are being replicated between my DMQ nodes. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt">The problem is that when the presentity records are being replicated from another SBC, the domain for that record stays as the IP of the original SBC. Then when the local_watchers is populated,
the presentity_uri doesn’t match, and no NOTIFY packets are sent as a consequence.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="font-size:11.0pt">What am I missing here? I can’t see anything in the docs about how to handle this, and I can’t find any examples in the list on how to handle this either, which suggests it isn’t as common of
an issue at it seems. See example of what I see in the presentity table below. In this case handset 103 is subscribed to BLFs for 103 and 104. A call came into 103 and generated an early state dialog in the presentity table.<o:p></o:p></span></p>

both SBC IPs. I am also registering from the handset using this FQDN now, and yet although my active_watchers table now expects a presentity URI of
<a href="mailto:XXX@sbc.fqdn">XXX@sbc.fqdn</a>, the presentity table is still using the IP addresses of the individual node that originated the dialog.<o:p></o:p></span></p>
