Refer to your manual on the SIP GSM GW and then inform us what exactly it needs for it to send an SMS then we can give you some sort of educated guess. Without this we have NO idea what gateway you're taking about... or what exactly it expects to send an SMS. /b On Jan 15, 2009, at 5:12 AM, Imthiyaz Ahmed wrote:

Hi

I have a IP to GSM gateway which supports SIP. How I can send SMS to the GSM phone using FreeSwitch + SIP GSM GW?

Thanks Imthiyaz
