I've just downloaded and installed NowSMSv5.51(Aug 23, 2004). But my gsm modem is a kludge we made it ourself and we have no driver for it. So I can't config it correctly. I am wonderring that buying a new modem would make it better. And Then I'd like to know something about direct MMS delivery. In my assumption, after I put a mms file on a webserver, I send an mms notification to mobile, it then will initiate a wap session to retrieve the mms file.Am I right? My Question is How the webserver is to act to the mobile's request, just like a normal http server or need something special there(wap stack...)? Waiting for your answer. Thanks. | |||

Usually one of the "Standard Modem Drivers" that comes with Windows is sufficient. The 57.6Kbps versions of the drivers expect the modem to support some specialised AT commands, but the 33600bps and below drivers will generally work with any GSM modem. (Also note that the speed referenced in the driver is a bit of a misnomer. For example, the 33600bps "Standard Modem" driver is configured to talk to the modem at 115200bps.) If you want to put a compiled MMS file on your own web server, you just need to make sure that the web server returns the "Content-type:" header "application/vnd.wap.mms-message" for the file. You don't need to worry about a WAP stack ... the mobile is going to talk to a WAP proxy/gateway, and that proxy is going to be the entity that actually requests the file from your web server (in most configurations). But, you should be aware that when you do this type of direct MMS delivery, there are many mobile operators that block message delivery from external MMSCs. (The issue is primarily a billing one ... the billing model for many operators is that the sender pays for sending an MMS, and it is free to the recipient. As the phone is configured to connect to a free GPRS access point for downloading MMS, that access point is restricted to only be able to download from the operator MMSC. See http://www.nowsms.com/howmmsworks.htm for more information.) -bn | |||

Thanks for your elaborate reply. Yet I have another question. Whether I have to adjust the image size to an appropriate value, or the NewSms deals with it, or the mobile terminal? Best Regards Semon | |||

Hi Semon, If you are sending an MMS notification pointing to a pre-compiled MMS URL on your web server ... then you would have to do any image adjustments, or rely on the mobile terminal to make its own adjustments. If you are using NowSMS as an MMSC, then NowSMS will perform image adjustments when the device connects to retrieve the message. (The device might also make adjustments.) If you are using NowSMS to route messages to an operator MMSC, then the operator MMSC would make any adjustments. (The device might also make adjustments.) -bn | |||
