Parameters
<varname>modems</varname> (string)
Define and configure one or more GSM modems.
modems_value = modem_definition *( ";" modem_definition )
modem_definition = modem_name "[" list_of_params "]"
list_of_params = modem_param *( ";" modem_param )
modem_param = name "=" value
The following parameters can be used:
d=device (mandatory) - Device associated with modem (/dev/ttyS0, /dev/modem,
etc.).
p=pin (optional) - SIM PIN - default
is NULL.
m=mode (optional) - Modem working mode
("ASCII","OLD","DIGICOM","NEW"). Default value is "NEW".
c=SMS_Center (optional) - SMS center
number for that modem. Default is the
SMS center set on the
SIM card.
b=baudrate (optional) - Default is 19600.
r=retry (optional) - How many times to try to re-send a
SMS that reported error. Default is twice.
l=looping (optional) - Time for modem to wait before performing a new check
for incomimg/outgoing SMS/SIP_MSG. Default is 20.
t=to (optional) - uri for sip header TO. Default is NULL.
s=scan (optional) - Values:
0: NOT SCAN uri from body sms, use URI in t=to.
1: SCAN uri from body sms (normal mode,
default mode, clasic mode)
2: SCAN MIX (both modes), First SCAN
Default is 1 (SCAN).
No default value, the parameter is mandatory.

modparam("sms", "modems", "Nokia[d=/dev/ttyS1];Siemens[d=/dev/ttyS2]")
...
<varname>networks</varname> (string)
Define and configure used GSM networks.
networks_value = net_definition *( ";" net_definition )
net_definition = net_name "[" list_of_params "]"
list_of_params = set_param *( ";" set_param )
set_param = name "=" value
The following parameters can be used:
m=msx_sms_per_call (optional) - Maximum number of
SMS send / received from that net in one
modem loop. Default is 10. This parameter was introduced to
avoid starvation.
Example of the starvation--a modem can send
SMS for more than 1 networks. If you
have a huge number of SMS for the first
network and the number of incoming SIP messages is equal
to the sent SMS per same unit of time,
the modem will never get to send SMS for
the next networks.
No default value, the parameter is mandatory.
Set <varname>networks</varname> parameter
...
modparam("sms", "networks", "D1 [m=10] ;d2[ m=20]")
...
<varname>links</varname> (string)
Define from which network each modem should send
SMS.
links_value = modem_assoc *( ";" modem_assoc )
modem_assoc = modem_name "[" list_of_networks "]"
list_of_networks = network *( ";" network )
No default value, the parameter is mandatory.
Set <varname>links</varname> parameter
...
modparam("sms", "links", "NOKIA[D1;d2]")
...
The modem NOKIA will send SMS from D1 and D2 net
(in this order !). if in a net queue are more then max_sms_per_call
SMS the modem will not
sleep before starting the next loop ! Shortly, if
messages are waiting to be sent, the modem will not go in sleep.
<varname>default_net</varname> (string)
The default network to use. If no one specified, the first defined
network is used. This parameter is useful only if the
"sms_send_msg" exported function is used (see ).
Set <varname>default_net</varname> parameter
...
modparam("sms", "default_net", "D1")
...
<varname>max_sms_parts</varname> (integer)
Shows in how many parts (SMS messages) a SIP message can be
split. If exceeded, the SIP message will be sent truncated and the SIP user will
get back another message containing the unsent part.
Default value is 4.
Set <varname>max_sms_parts</varname> parameter
...
modparam("sms", "max_sms_parts", 10)
...
<varname>domain_str</varname> (string)
Specify a fake domain name to be used by the gateway. The Contact
headers and the From header from request will be construct based on
this fake domain name. It's useful when the gateway is
transparently hidden behind a proxy/register (located on different
machines).
Default is the name of the machine the gateway is running on.
Set <varname>domain_str</varname> parameter
...
modparam("sms", "domain_str", "foo.bar")
...
<varname>sms_report_type</varname> (integer)
If the modem should ask for SMS confirmation
from the SMS Center. If the
SMSC reply with an error code, the gateway will
send back to SIP user a SIP message containing the text (or
part of it) that couldn't be send. Two report mechanisms are
implemented:
1 - the reports are delivered by the GSM device as
SMS reports (so far supported only by Nokia modems);
2 - the reports are delivered as async. CDS responses
(supported by almost all modems, except Ericsson).
Default is 0 (no report).
Set <varname>sms_report_type</varname> parameter
