Q8300005: What is the throughput of SMPP? So, how many messages per second can be sent/received using an SMPP channel?
With an SMPP channel, you can send and receive up to 20 messages per second or faster. It all depends on the (connection to the) SMPP provider and the performance of your database. See also FAQ #8300005. If you use triggers to process incoming messages, it is strongly recommended to use MS SQL as message database instead of MS Access. See also FAQ #8800100.

Q8300035: How can I specify a range of addresses in the Address Range property of my SMPP Channel?
The 'Address Range' parameter is used in the bind_receiver and bind_transceiver command to specify a set of SME addresses serviced by the ESME client. A single SME address may also be specified in the address_range parameter. UNIX Regular Expression notation should be used to specify a range of addresses. Messages addressed to any destination in this range shall be routed to the ESME. Note: It is likely that the addr_range field is not supported or deliberately ignored on most Message Centers...

Q8300050: Which SMPP commands are communicated with the SMPP provider to send/receive a message? Can I see a log of all operations?
Yes, you can see all commands using a trace file. By default, tracing is NOT switched on. Tracing is enabled/disabled per channel. You can enable tracing for SMPP by specifying a log file for the particular channel in the registry:     HKLM\Software\ActiveXperts\SMS Messaging Server\Trace\SMPP.xxxx , where xxxx is the actual channel number. After you change this registry value, you MUST restart the SMS Messaging Server engine (service) for the changes to take effect...

Q8300080: I setup an SMPP channel, using the smpp.activexperts-labs.com demo provider. I submitted a message but never received it on my mobile phone. Any idea?
Most probably, the provider that is used by the ActiveXperts gateway does not cover your provider's network. Please contact support and tell them to which cellphone number in which country you are trying to send messages. Support will then try to create a route to your mobile number.

Q8300110: After a couple of minutes, my SMPP connection is suddenly disconnected. What happens?
SMPP uses a link keep alive timer. Once in every x seconds the client should send an enquire_link packet to the SMPP server, if this packet is not received the SMPP server will close the connection. This will also happen if your enquire_link timer is set to high. Please try to set the keep alive timer to a lower value. This can be done from the SMPP channel properties window in the channel view of the SMS Messaging Server Manager application.

Q8300100: I want to send SMS messages to my recipients, but I don't want the GSM telephone number be displayed on their mobile phones. Instead, the name of our company should be displayed. Is this possible?
Yes it is possible. This is also called an 'Alphanumeric Source Address'. This text can be eleven characters long. To use an alphanumeric source address, you need to assign the display string to the SMPP Channel's Source Address property. It is recommended to set the Source TON property to 5 when using alphanumeric displaynames, because it is required by some providers. You can change the above properties in the SMPP Channel's Advanced Settings box.

Q8300030: When I connect to my SMPP provider in Transceiver mode (Send and Receive both enabled), I cannot send or receive messages anymore. If I just enable only Send or only Receive, it works fine. What's the problem?
Most probably, your provider only supports SMPP v3.3. Transceiver mode (send and receive simultaneously) can only be used for providers that support SMPP v3.4 or higher. To send and receive simultaneously, just create two channels: enable Send-only for the first one and Receive-only for the second one.

Q8300060: Some characters like the at-sign, the euro symbol and pound symbol are not displayed correctly on the recipients phone when sending SMS through my SMPP connection. What's wrong?
Your SMPP provider does not convert these chars to the GSM alphabet automatically. You have to convert the messages to GSM alphabet. To do this, go o Configuration=> Channels, select the SMPP channel and click on the pencil to modify the properties. The Charset setting can be found in the "Advanced Settings" section of the SMPP channel properties. Set this value to "GSM".

Q8300040: I'm using 4 SMPP channels now. Can I add more SMPP channels?
By default, the maximum number of SMPP channels is set to 4. To increase this number, change the following registry key: HKLM\Software\ActiveXperts\SMS Messaging Server\Performance\ThreadsSmpp. Please note that the engine will consume more resources when this number is increased, because it needs to create additional threads to handle these channels.
