The feature you want to use is sending DTMF tones. There are several
possibilities (INFO method, RTP ...). You have to make sure that the
gateway accepts the method used by the SIP phone (or vice versa). AFAIK
you can configure the grandstream phones.

Hello everyone,
I have a question. I have set up SER with couple of grandstream phones
and i am using VEGA gateway. It works great. I have two dial plans for
outgoing calls:
# Destination PSTN or H323?
if( uri=~"^sip:9[0-9]*@voip.sip_proxy.com" )
{
route(1);
break;
};
if( uri=~"^sip:\*74@voip.sip_proxy.com" )
{
route(2);
break;
};
# ------------ Send it to our PSTN ----------------------
route[1] {
# Route to PSTN Gateways(s)
if (uri=~"^sip:9[0-9]*@voip.sip_proxy.com") { ## This
assumes that the caller is
log("Forwarding to PSTN\n"); ## registered
in our realm
strip(1);
#t_relay_to_udp( "voip.gateway.com", "5060" );
rewritehostport("voip.gateway.com:5060");
forward(uri:host, uri:port);
break;
};
}
route[2] {
if (uri=~"^sip:\*74@voip.sip_proxy.com") { ## This
assumes that the caller is
log("Picking up a Call on PSTN\n"); ##
registered in our realm
#t_relay_to_udp( "voip.gateway.com", "5060" );
rewritehostport("voip.gateway.com:5060");
forward(uri:host, uri:port);
break;
};
}
That is working fine. This *74 is for call pick up if someone is
wondering what the hell is that :)
However once I dial any number that has a menu options like: Press 1 for
english, 2 for spanish and so on, i can't do anything. I keep on
pressing the numbers on my key pad but nothing is going on. I tried with
the 9 as well, ( to append 9 before the number ), but nothing. Is it
possible to have that with ip phones at all? Is there a dial plan for
something like that? I guess I am little bit confused 'cause it's an
established call, not a new one, so i am not sure where to start
looking. Any ideas?
thanks.
