- 192.168.1.1 - router's IP address, replace it with your LAN IP or WAN IP (when connecting remotely)
- SMS related post/get commands. Possible values are:
- sms_list - view all SMS messages in storage
- sms_read - read a single SMS message by specified SMS index (number)
- sms_send - send an SMS message to specified number
- sms_total - display SMS storage statistics
- sms_delete - delete a single SMS message by specified SMS index (number)
- & - separation symbol. After specifying the SMS command, other parameters must be separated by an ampersand (&) symbol
- username - SMS POST/GET configuration user name
- password - SMS POST/GET configuration password
- number - SMS message index or (depending on context) recipient's phone number. SMS message indexes can be viewed with the sms_list command.
Correct phone number format is:- 00 - number must be preceded by two zeros
- <country_code> - the next following element is the number holder's country code
- <receivers_number> - phone number of the recipient
For example, a valid number would be 0037012345678 (370 is country code and 12345678 is the receiver's phone number, all preceded by 00)
- text - SMS message text
Email to SMS
Email to SMS is a function that connects to your email account and checks its inbox at the specified frequency. If it finds any new received emails with a specific subject (phone number in email subject), it sends the body of the email as an SMS message(s) to the recipient specified in the email subject field.
Important note: all POP3 server email messages from inbox will be deleted when using this service.
| Field | Value | Description |
|---|---|---|
| Enable | yes | no; default: no | Turns Email to SMS on or off. |
| POP3 server | host | ip; default: none | Email service provider's POP3 server address (can be looked up online). |
| Server port | integer [0..65535]; default: none | Email service provider's POP3 server port (can be looked up online). |
| User name | string; default: none | Email account username, used in authentication when connecting to the email client. |
| Password | string; default: none | Email account password, used in authentication when connecting to the email client. |
| Secure connection (SSL) | yes | no; default: no | SSL is a protocol for transmitting private documents via the Internet. SSL uses a cryptographic system that uses two keys to encrypt data − a public key known to everyone and a private or secret key known only to the recipient of the message. |
| Max. email symbol count | integer; default: 160 | Limit of symbols that can be contained in the email body of text. Emails that contain more symbols than it is specified in this field will be ignored. |
| Check email every | time [1 minute to 15 days]; default: 1 minute | Email inbox check interval. |
Additional note: you may have noticed that there is no option where you can specify the recipient's phone number. As mentioned earlier, Email to SMS doesn't forward all emails, just the ones that are meant to be forwarded. Only emails with the recipient's phone number in the subject will be forwarded to SMS.
Correct phone number format is:
- 00 - number must be preceded by two zeros
- <country_code> - the next following element is the number holder's country code
- <receivers_number> - phone number of the recipient
For example, a valid number would be 0037000000000 (370 is country code and 00000000 is the receiver's phone number, all preceded by 00).
Scheduled SMS
Scheduled SMS allows you to set up the router to periodically send SMS messages to a specified number. Scheduled messages are managed in rule form. Therefore, to configure a new Scheduled Message, we must first create a rule. To create a new rule, type in a phone number in the Phone number field located in the Scheduled Messages Configuration section and click the Add button located next to it.
After this you will be redirected to the Scheduled Messages Configuration window where you can configure all parameters related to the rule. Once you save the configuration, you will be redirected back to the Scheduled SMS page, where you will see your new rule in the Messages To Send section:

SMS Forwarding
The SMS Forwarding tab contains three sections:
Each of which can be used to set up forwarding of incoming SMS message to either HTTP, email or another phone number.
SMS Forwarding To HTTP
The SMS Forwarding To HTTP function forwards received SMS messages to HTTP by using either Post or Get methods. The figure below is an example of the SMS Forwarding To HTTP section and the table below provides information on the configuration fields contained in that section:
| Field | Value | Description |
|---|---|---|
| Enable | yes | no; default: no | Turns SMS Forwarding To HTTP on or off. |
| Forward SMS Utilities rules | yes | no; default: no | When checked, the router will also forward SMS Utilities rules. By default router will not forward SMS messages which are SMS Utilities rules. |
| Use HTTPS | yes | no; default: no | Check to use the HTTPS protocol instead of HTTP. |
| Encode message text to Base64 | yes | no; default: no | Message text will be encoded to a Base64 string. Enable this to preserve Unicode characters in the message text. |
| HTTPS Certificate verification | Ignore | Verify; default: Ignore | Indicates whether the server's certificate will be ignored or verified. |
| Method | Post | Get; default: Get | Defines the HTTP transfer method. |
| URL | host | ip | host:port | ip:port; default: none | URL or IP address to which the messages will be forwarded. By default, the router forward messages to the default HTTP port (port 80). To specify a different port add a colon (:) symbol followed by the port number (for example, 192.168.1.1:81). |
| Number value name | string; default: none | Name to assign the sender’s phone number value in query string. |
| Message value name | string; default: none | Name to assign the message text value in query string. |
| Extra data pair 1 / Extra data pair 2 | string; default: none | Transfers extra information through the HTTP request. Enter variable name on the left field and its value on the right. For example, when using the Post method, one may enter some static information about the device, like 'Router name' on the left and 'RUT240' on the right. This can also be utilized when using the Get method to request data from an HTTP server. |
| Mode | All messages | From listed numbers; default: All messages | Specifies whether all messages should be forwarded or only those received from specific numbers. |
| Sender's phone number | phone number; default: none | Phone number(s) that will qualify for forwarding. To add multiple numbers, click the  symbol. This field becomes visible when the "Mode" field value is set to 'From listed numbers'. |
Forwarding To HTTP example
This example will atempt to explain how to use the data fields in SMS forwarding to HTTP configuration. The fields in question are Number & Message value name and Extra data pair 1 & 2 fields. The figure below is the configuration we'll be using for this example:
If you configure the router as seen in the image above and send an SMS message to the router containing the text Hello!, from the number +37000000000, the specified server should reiceve an encoded query string that looks like this:
Sender=%2B37000000000&Text=Hello%21&Name=RUT240&Code=RUT240%2006E000
The & symbol separates the the key-value pairs, while certain characters (like +, ! and the space symbol) are encoded in UTF-8. When decoded it might look something like this:
Sender: +37000000000 Text: Hello! Name: RUT240 Code: RUT240 06E000
SMS Forwarding To SMS
The SMS Forwarding To SMS function forwards received SMS messages to one or several other phone numbers. The figure below is an example of the SMS Forwarding To SMS section and the table below provides information on the configuration fields contained in that section:
