Setting Up SMTP Message Notifications
Using SMTP, Unity Connection can send text notification to notify users that they have received a new message or calendar event. Text notifications can be sent to any device that supports SMTP, for example, email addresses, mobile phones, and text pagers.
To enable Unity Connection to send text notifications using SMTP, your Unity Connection server must be configured to relay messages through a smart host. If Unity Connection is configured to deliver text notifications but has not been configured to relay messages to a smart host, the notification attempt fails and the notification is put in the Unity Connection SMTP Server badmail folder.
When a Unity Connection user receives a new message, Unity Connection can send a text notification to an email address. (When you set up this type of notification, you can configure Unity Connection to include a link to the Cisco PCA in the body of the email message. On the Edit Notification Device page for the user, check the Include a Link to Cisco PCA in Message Text check box.)
To enable SMTP notifications, do the following tasks:
1. Configure the SMTP smart host to accept messages from the Unity Connection server. See the documentation for the SMTP server application that you are using.
2. Configure the Unity Connection server. See the To Configure the Unity Connection Server to Relay Messages to a Smart Host.
3. Configure Unity Connection users or templates. See the “SMTP-Compatible Notification Devices” section in the “Setting Up Features and Functionality Controlled By User Account Settings in Unity Connection 8.x” chapter of the User Moves, Adds, and Changes Guide for Cisco Unity Connection Release 8.x, at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/8x/user_mac/guide/8xcucmacx/8xcucmac040.html.
Alternatively, users can set up their own SMTP-compatible devices using Messaging Assistant.
To Configure the Unity Connection Server to Relay Messages to a Smart Host
Step 1 In Cisco Unity Connection Administration, expand System Settings, expand SMTP Configuration, then select Smart Host.
Step 2 On the Smart Host page, in the Smart Host field, enter the IP address or fully qualified domain name of the SMTP smarthost server. (Enter the fully qualified domain name of the server only if DNS is configured.)
Step 3 Select Save.
Setting Up SMS (SMPP) Message Notifications
With the services and information provided by a wireless carrier, mobile messaging service provider or similar company, Unity Connection can use the Short Message Peer-to-Peer (SMPP) protocol to send message notifications in the Short Message Service (SMS) format to mobile phones and other SMS-compatible devices when users receive new messages. SMS is a “store and forward service,” which means that messages are not sent directly to the device used by the message recipient. Instead, an application like Unity Connection—known as an External Short Message Entity (ESME)—submits a message to the SMS Center (SMSC). The SMSC then forwards the message to the device.
Advantages Over SMTP Message Notifications
An advantage of using SMS is that the user device often receives message notifications much faster than when using SMTP. The user device does not have to be on the wireless network at the time that Unity Connection sends the message to the SMSC, nor when the SMSC forwards it. The wireless network holds the SMS messages until the device is available; when the device is available, the delivery of the queued messages to the device takes just a few seconds. In addition, you can configure Unity Connection so that each notification message replaces the previous one. Note that this functionality may not be supported by all mobile service providers.
SMS Message Length Limitations
An SMS message is a short text message. The acceptable message length for an SMS message varies depending on the service provider, the character set used to compose the message text, and the specific characters used in the message text. The message count (assuming that users choose to include the message count) is not included in the total message length.
Character sets available include:
- Default Alphabet (GSM 3.38), 7-bit characters
- IA5/ASCII, 7-bit characters
- Latin 1 (ISO-8859-1), 8-bit characters
- Japanese (JIS), multi-byte characters
- Cyrillic (ISO-8859-5), 8-bit characters
- Latin/Hebrew (ISO-8859-8), 8-bit characters
- Unicode (USC-2), 16-bit characters
- Korean (KS C 5601), multi-byte characters
For 7-bit character sets, a maximum of 160 characters can fit into an SMS message; for 8-bit character sets, the limit is 140 characters; for 16-bit character sets, the limit is 70 characters; for multi-byte character sets, the limit is somewhere between 70 and 140 characters, depending on which characters make up the text of the message. (For multi-byte character sets, most characters are 16 bits; some of the more common characters are eight bits.)
Note Not all mobile phones support all character sets; most support the GSM 3.38 default alphabet.
When setting up SMS (SMPP) message notifications, consider that service providers typically charge for each SMS message or group of messages sent. Thus, the more SMS (SMPP) message notifications that Unity Connection sends to user devices, the higher the costs to your organization. For this reason, you may want to restrict the use of this feature to a group of users (you can do so by assigning owners to the SMPP providers that you create), or you may want to ask users to limit the number of message notifications that they receive by message type or urgency. For example, users can specify in the Unity Connection Messaging Assistant that Unity Connection sends message notifications only when new urgent voice messages arrive.
Task List for Setting Up SMS (SMPP) Message Notifications
To enable SMS (SMPP) message notifications for users with SMS-compatible devices, do the following tasks:
1. Set up an account with a mobile messaging service provider that offers SMS messaging. Unity Connection works with any service provider that supports the SMPP version 3.3 or SMPP version 3.4 protocols.
2. Gather the information needed to allow Unity Connection to communicate with the SMPP server at the SMSC affiliated with your contracted service provider, and enter the information on the SMPP Provider page. See the To Set Up an SMPP Provider.
3. When the Unity Connection server is set up behind a firewall, configure the TCP port that is used by the SMPP server when connecting to Unity Connection to allow incoming and outgoing communication between Unity Connection and the SMPP server.
4. Enable SMS (SMPP) message notification and set up an SMS-compatible device to receive notifications for a user account, and then test to see if the device receives the SMS (SMPP) notification as expected. If notifications are not working, confirm that you entered the settings on the SMPP Provider page as indicated in the documentation that your service provider gave you. Contact your service provider for assistance, as needed.
Procedures for setting up a device and enabling SMS (SMPP) notifications are in the “SMS-Compatible Notification Devices” section in the “Setting Up Features and Functionality Controlled By User Account Settings in Unity Connection 8.x” chapter of the User Moves, Adds, and Changes Guide for Cisco Unity Connection Release 8.x, at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/8x/user_mac/guide/8xcucmacx/8xcucmac040.html.
5. Repeat the previous task for additional users.
To Set Up an SMPP Provider
Step 1 In Cisco Unity Connection Administration, expand System Settings > Advanced, then select SMPP Providers.
Step 2 On the Search SMPP Providers page, select Add New.
Step 3 On the New SMPP Provider page, verify that the Enable check box is checked.
Step 4 Enter a Name for the provider.
Step 5 Enter the System ID given to you by your service provider.
Step 6 Enter a Host Name/Address that is the SMSC Host name or IP address given to you by your service provider.
Step 7 If applicable, enter the Source Address given to you by the service provider. If your provider did not specify a value, leave the field blank.
Step 8 Set the Owner, as follows:
- To restrict provider use, select a user as owner of the selected SMPP provider. Select User and then select the applicable user in the list.
- To allow the SMPP provider to be used by all users with associated SMS (SMPP) notification devices at a location, select System as owner of the selected SMPP provider.
Step 9 Select Save.
Step 10 On the Edit SMPP Provider page, enter the Port, which is the port number that is used by the SMSC to listen for incoming connections
