<p style="margin-left:35.4pt">Hello,<o:p></o:p></p>
<p style="margin-left:35.4pt">the problem I see with 1) is in case one wants to set there SIP URI for other transports than UDP, the ; is used to separate URI parameters as well. I think now it supports only UDP anyhow, but to have it open for future, this
should be kept in mind<o:p></o:p></p>
<p style="margin-left:35.4pt">From my point of view, for the modules I work with and develop, the style of separating with ; within same modparam value suits for sip-params-like-values, respectively name1=value1;name2=value2; ... because parase param function
can be used. In this case, a value can contain ; but the entire value has to be enclosed in quotes.<o:p></o:p></p>
<p style="margin-left:35.4pt">So far 1) maybe another delimiter between URIs should be used, like comma.<o:p></o:p></p>
<p style="margin-left:35.4pt">Personally I would like more for 2), it is more compact in case one uses many addresses, not to have a single very long value, but I don't really mind 1) with a different separator (at the end both variants can be supported :-)
, but more coding is needed, without much benefits ...)<o:p></o:p></p>

<span lang="EN-GB">one question about a planned extension in the DMQ module. Right now the module supports only one server in the notification_address parameter. It is possible to set multi_notify to 1, and then the module will resolve the one sip URI over
DNS to multiple servers, thought.</span><o:p></o:p></p>
