Here are some notes I put together that help avoid issues should you need to configure Informacast.
These notes were tested with CUCM 10.5.2 and Cisco Paging Server (Informacast) 11 in a lab environment. It is the responsibility of the person making configuration changes in their network to know the full impact of the configurations. This document does not remove the need to review official Cisco documentation as the information below supplements the official documents.
NOTE: This document provides many details that you can use, or change, however you see fit. Some examples are Application User names, partition and CSS names, SNMP string, etc...
At this point you make a choice about how to integrate InformaCast. You can either integrate using CTI route points, or a SIP trunk. Both options are listed below with the first option listed being CTI route points.
NOTE: InformaCast can support multiple CTI route points as long as they are created in Communications Manager and associated to the InformaCast application user.
TIP: Instead of creating a CTI route point for every number you need for DialCasts, you could also add multiple lines to a single CTI route point. Another option would be to use wild card patterns to match a range numbers.
NOTE: You should only see phones that are registered
Please be advised that only registered phones will show in InformaCast when CUCM is polled.
This is only needed if you did the SIP integration method. If you did the CTI Route Point method (JTAPI method) you can skip this part.
Everything above this line is the bare minimum to integrate the Cisco Paging Server. Everything below this point is recommended but not always necessary.
These steps were taken directly from the Informacast Installation & User Guide.
When you initially install InformaCast Virtual Appliance or whenever you change versions of CUCM, you need to update the JTAPI library used by InformaCast Virtual Appliance to the same version used by your CUCM server.
Note: Updating JTAPI through the Virtual Appliance will update the JTAPI version for all of the Singlewire applications that use JTAPI.
Step 1. Log into Webmin (https://<YourInformaCast'sIP>:10000/).
Step 2. Go to System | Bootup and Shutdown. The Bootup and Shutdown page appears.
Step 3. Scroll down the list of actions until you come to Singlewire’s.
Step 4. Select the singlewireInformaCast checkbox and (if applicable) the singlewirePTT checkbox.
Step 5. Scroll down the page and click the Stop button. It will take a minute or so for your application(s) to stop.
Note: Leave this window open. You will come back to it.
Step 6. Use an SSH client (Singlewire recommends PuTTY) to access InformaCast’s command line interface.
Step 7. Open PuTTY. The PuTTY Configuration window appears.
Step 8. Enter InformaCast’s IP address in the Host Name (or IP address) field.
Step 9. Leave the Port field at its default of 22.
Step 10. Click the SSH radio button.
Step 11. Click the Open button. The command-line interface for InformaCast appears.
Step 12. Enter admin at the prompt and press the Enter key.
Step 13. Enter changeMe at the prompt and press the Enter key. The command-line interface refreshes, showing you that you’re logged in.
Step 14. Enter updateJTAPI <CUCM IP Address>, where <CUCM IP Address> is replaced by the IP address of your CUCM, at the prompt and press the Enter key. If an error condition occurs, please contact Singlewire Support.
Step 15. Enter exit at the prompt and press the Enter key.
Step 16. Go back to the Bootup and Shutdown page.
Step 17. Select your checkbox(es) again and click the Start button. It will take a minute or so for your application(s) to start.
You can use either regardless of whether or not you do SIP integration; however, you may want to use JTAPI if you are paging to phones using a locale that is non-English (this can be found on the phone web-page see image below). What differs based on integration method is busy detection.
InformaCast uses different busy detection methods depending on how you send messages to the phones (HTTP or JTAPI).
HTTP:
* Busy detection only works with phone locales running English loads
CTI:
* Works with non-English phone locales
Busy detection also works differently according to protocol as well as line type and line state.
Shared line with call in use on another phone, no call on hold: CTI: idle HTTP: idle
Off hook, collect digits: CTI: busy HTTP: not busy
Talking, active call: CTI: busy HTTP: busy
On hold, inactive call on shared line: CTI: busy HTTP: not busy
On hold, inactive call on unique line: CTI: busy HTTP: not busy
Confirm your DNS configuration on CUCM is correct.

You may also be using a community string that exceeds the maximum number of characters for the community string. If you are copying the community string from CUCM and pasting it into the Informacast configuration, try typing it in to see if you can type the whole string. In Informacast verison 11 the maximum number of characters is 18.
If you configure informacast and the phones light up but don’t get audio when you are paging them, this is 99% of the time an issue with multicast routing and not an issue with your Cisco IP Telephony servers/devices. You can gather a pcap from Informacast and a phone to confirm Informacast is sending the audio while the phone is not receiving the audio. This would confirm the issue is in the network.
NOTE: If you are using Meraki switches, they have IGMP snooping enabled by default. This can cause issues and needs to be disabled by Meraki. Once you contact them and have them disable IGMP snooping, test the paging again.
The link below will take you to a 12 minute video that covers how to troubleshoot this issue.

When I need 2 Paging Servers, what can i do?.
I have a paging server and cucm in main site, they are working ok. But the client have a remote site and multicast doesnt workin. I think install other Paging Server in Site Remote inside same LAN of Ip Phone, but I cannot add a Second paging Server in CUCM via URL Authentication. There is other way of implement this application?.
Thanks
Possibly, I will need to test.
It would require you to use the Send Commands to phones using JTAPI setup and I won't know if it works until I test some time soon.
The auth URLs would be changed back to the original URLs in the setup. I will let you know how it goes when I am done testing.

Somebody in Internet say me that only using CTI and not URL Authentication is possible doing working. I dont know if Paging working No URL Authentication. Is possible that? All of guides indicate URL Authentication and Secure, not regard if CUCM and Paging are by SIP or CTI.
Yours commnets.

Singlewire makes a paging gateway that can send the multicast traffic as unicast across the WAN. For the remote site you could just get the paging gateway and configure it in the receipt group for that remote site.
Hi,
thanks a lot for your guide.
Is the system able to interrupt or intercom calls, before sending broadcast?
I just can enable idle phones.
Thanks
Yes, I have done it without using the auth URL. Usually this is when you want to add another site there is a centralized CUCM with InformaCast installed currently and SIP integration is not a valid solution.
This is when you have to do a CTI integration. If you have any questions let me know.
