Hi Jean,
 
Please give the names separated by commas to get the information of all the devices for now...
<Item xsi:type="xsd:string"> SEP0021BBBBBBBB, SEP0015AAAAAAAA, SEP002199999999 </Item>
 
I think your query should work fine. We have seen issues with older versions of CallManager... Could you please let me know the CUCM version in which you are facing this issue?
 
Thanks and Regards,

One observation, in your original request, the array was only indicating one row:
 
<SelectItems soapenc:arrayType="ns2:SelectItem[1]" xsi:type="soapenc:Array"><item href="#id1"/>
 
I believe this needs to reflect the # of select items.
 
Interesting that the comma separated list works...I'd be wary of that since it's not specified in the docs/schema that way AFAIK, and therefore may be susceptible to being changed without warning.

Are you requesting 200 devices info at a time?  That is are you sending 200 device names in your request?
 
If so be careful you can get bad results:  With NodeName=nil you can get responses for each device from up to three CUCM (seems to happen most on newer systems and then settle out), so if you ask for info on 200 unique device names you could get 66 unique device items returned by each of three CUCM for a total of 198 infos in the response.  So thats ~134 devices you didnt get info returned for since the response can contain a maximum of 200 device info items.
 
Also, when getting multiple items returned for the same device the timestamps become very important.  Some of the CUCM will report the device as UnRegistered while one will report it as Registered (the one that it is actually registered to) and this one generally has the latest timestamp.  Finally, I've seen the timestamps match with one CUCM reporting UnRegistered and another reporting Registered, in this case I mark the phone as registered.
 
Maybe you figured this out already and only request a max of 66 devices; or i suppose if you knew the NodeName that all the phones were registered to you could request all 200 devices from it but that is going to blow away fail-over, there could be a more appropriate solution but I'm not sure what it is. 
 
Here is my request incase it helps you with the SAOP array, i remember this as a major pain:

Also, here is the code for the SOAP array portion (c#):
 
xml.WriteStartElement( "soapenc:Array");
xml.WriteAttributeString( "id", "id2" );
xml.WriteAttributeString( "soapenc:arrayType", selectItems );  //selectItems = tns:SelectItem

for(int i =0; i<names_.Length; i++)
{
xml.WriteStartElement( "Item");
xml.WriteAttributeString( "xsi:type", "tns:SelectItem");
xml.WriteStartElement( "Item" );
xml.WriteAttributeString( "xsi:type", "xsd:string" );
xml.WriteRaw ( names_ );
xml.WriteEndElement();
xml.WriteEndElement();
}
xml.WriteStartElement( "Item");
xml.WriteAttributeString( "xsi:null", "1" );

Restricting the query to only Registered devices should eliminate the issue with getting multiple results for the same device name, since the device can only be actively registered to one node.
