/mcpWhat to do next If the Unity Connection server has not been properly enabled to use SMTP smart host for message notification, it places SMTP notification messages in the Unity Connection SMTP server badmail folder Note Setting Up SMS Message Notification With the services and information provided by a wireless carrier, mobile messaging service provider, 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. 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. You can configure Unity Connection so that each SMS notification message replaces the previous one. Note that this functionality may not be supported by all mobile service providers. SMS Message Length Limitations 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. 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.) Not all mobile phones support all character sets; most support the GSM 3.38 default alphabet. Note Cost Considerations System Administration Guide 179 Notifications Setting Up SMS Message Notification
