Diafaan SMS Server uses five status codes:
100 - The message is in the send queue
200 - The message is sent and accepted by the gateway
201 - The message is delivered to the mobile phone
300 - The message is rejected by the gateway
301 - The message could not be delivered to the mobile phone
Normally, every SIM card has a different phone number and messages that are sent with a mobile phone or GSM modem always have the number of its SIM card as the sender ID. In theory the mobile operator can publish multiple SIM cards with the same phone number but they will probably only do that for very specific applications.
Most companies that support a large amount of customers with one sender ID use an Internet based SMS service provider, often with the SMPP protocol. For large scale applications, GSM modems are usually too slow and limited.
1. Could you please provide full list of status codes with explanation?
2. This question bothers me much - i'd like to have ~4-8 modems, every one with it's own SIM card, but when i send messages, i'd like them to be shown as same number, always. Any way to achieve this? I've seen companies who claim, that they are using one number only, and they are providing services for a lot of customers. How can it be done?
