Created by: James McHugh on 20-04-2011 02:02:41 PM Hi all, I am developing an application to send text pages to the Cisco 7925 using XML. One issue I have run into is how to determine the IP address of a phone that I want to send a message to if I only know the name. Do I need to use AXL to query Call Manager each time I need to get the IP? It seemed in some of the docs I read that using AXL was not for high volume which this could potentially lead to. Is there any other way to determine the IP address? I am using C# in Visual studio 2010 . Thanks

Subject: RE: Determining the IP address of a phone Replied by: James McHugh on 20-04-2011 02:15:00 PM I guess I should be clearer. I do not know the DNS name of the phone, I know the Cisco name as in SEP002333417581 . I didn't think that was available via SNMP?
Subject: RE: Determining the IP address of a phone Replied by: NIGEL WARBURTON on 20-04-2011 02:15:55 PM Yup, SEP000011112222 is available in SNMP for sure.

I have always found that sending XML to the phone is best done via the sendData CiscoTerminal method. That way, you don't need to know the IP address of the phone and you don't have to mess around with SNMP...

Wasn't sure though if hitting on the Call manager server to get the IP was a good idea if it might happen a few hundred times a day. I will try that though. Thanks

Richard Siebels has created a new message in the forum "IP Phone Services Questions":
-------------------------------------------------------------- The way we do it is straight from the IPPS admin guides. We use the RISport of CallManager via a SOAP call to get the IP address. You can send a executeItem command in XML and have the phone then initiate the Service URL needed to get your page data, or any other application you want to initiate. -- To respond to this post, please click the following link:

Subject: RE: Determining the IP address of a phone Replied by: James McHugh on 20-04-2011 02:39:49 PM I'd rather not get into SNMP unless I have to. Has anybody done that from .NET? I'd rather not have to reinvent the wheel for this tiny piece of the project.

Subject: RE: Determining the IP address of a phone Replied by: Richard Siebels on 20-04-2011 04:02:33 PM Using the RISport seems to be very efficient. We do have sites where we are doing a lot of queries and we have limited the number of hits on the server by caching IPs in our system for a period of time. If we get a failed attempt then we will query for the current IP and update our data then resend. The other thing to remember is that RIS only returns 100 records at a time so if you are sending a page to a couple hundred phones you will need to query multiple times for a page. This is where the caching (storing in local app database) really pays off.
