Q5240190: 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 ServerKeepalive to a value of '30'.If this does not help, please ask your provider to assist you solving this issue.

Q5240140: When I try to send a message using the ActiveXperts SMPP gateway, the software tells me that the message has been successfully submitted but the message never reached my phone, what can i do?
Most probably, the provider that is used by the ActiveXperts gateway does not cover your provider's network, and a different route must be selected. The ActiveXperts gateway can use different SMPP providers to route the SMS messages. You can select another route by setting the SMPP SystemType value to 'AX1001', 'AX1101' and 'AX1103'. If this does not work, 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...

Q5240030: How can I setup my SMPP provider so I can receive SMS messages through SMPP?
You need a so called "SIM hosting" contract with your SMPP provider. This means that the SMPP provider associates a GSM modem (including a SIM card) with their SMPP server. All messages received on this GSM Modem are forwarded to your account. Alternatively, you can set up such a configuration yourself using the SMS Messaging Server.

Q5240070: 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, but only through the SMPP protocol and HTTP protocol. It is not possible using a GSM modem (limited by the GSM protocol). The feature 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 SystemSourceAddress property. It is recommended to set the SystemSourceTON property to '5' when using alphanumeric displaynames, because it is required by some providers.

Q5240045: When I connect to my SMPP provider in transceiver mode, I cannot send or receive any message. However, I can send out messages when using transmitterl mode. What's the problem?
