When using a phone as the modem on the SMS/MMS gateway, we experience that people we send sms-messages to are responding with an SMS to the gateway's phone number. We'd like some way to hide this number or even better - an easy way to relay those received messages to one or more email addresses. Is this possible?

Olaf,

You can't hide the phone number on a GSM modem connection. However ...

In the latest release (v4.20), we added a function that allows received SMS messages to be automatically forwarded to an e-mail address.

At this point, it's only documented in the readme.txt. (We expect to overhaul the docs to cover new features in conjunction with the next major release.)

Here's the relevant info from the readme:

SMSGWS: Add support for received SMS messages to be routed to an e-mail address. Configure a receive command in the "2-way" dialog, with the "Command to Execute" set "mailto:user@domain", and received messages that match the defined prefix will be sent via e-mail to "user@domain". (Note: This feature sends outbound e-mail via the MMSC, so the MMSC must be active to support this feature.)

...

In a simple case, the MMSC needs to have an SMTP relay host set with the IP address or host name of an SMTP server that will allow the gateway to at least get a message routed to the "mailto:" address that you configure.

Some MMS related fields might be required on the MMSC configuration, but you can supply dummy values.

I would recommend that you "Enable E-Mail to SMS Support", and define a "domain name for SMS e-mail" that can get routed back to the gateway via SMTP ... at least in your local environment.

I recommend this because when the "mailto:" link is used, the reply address in the e-mail message for the SMS orignated message is phonenumber@domain.name.for.sms.e-mail.

Another tip/trick, related to NowSMS and sending out to e-mail ...

In a normal configuration, in order to use an e-mail client to send an SMS out through the NowSMS gateway, you have to configure the client to use SMTP AUTH. As that can be a little difficult, there's another trick in recent versions.

In the MMSC.INI file, under the [MMSC] section header, a setting named SMTPIPAddressList can be defined. This setting can contain a list of IP addresses (comma delimited, no white space) that are allowed to send through the SMTP interface of the gateway without requiring SMTP AUTH. Wildcards are supported (e.g., SMTPIPAddressList=192.168.1.*,192.168.10.12).

So with that setting in place, you could easily reply back to the SMS messages from e-mail as well.

Thanks for the info, Bryce. It works just fine. Seems like an easy way to set up a 2-way email to SMS service. BTW, is the keyword terminated by the following space character ?

Well, I'm not sure that it's easy ... but it works. So we'll settle for that today!

The keyword is terminated by a space character or other white space.

Not if you are using a GSM modem (or GSM phone as modem).

Many SMS service providers allow this when you send messages through a service ... it is just not allowed with a GSM modem/phone.
