How to change the modem to Network model?

Question: The default mode of tethered SIP data call is Relay model. How do I change to Network model?

Answer:
The mode can be changed by "AT+CRM" AT command as follows:
a. Change to Relay model: AT+CRM=1
b. Change to Network model: AT+CRM=2

Alternatively, you can change the default value of the AT Command table as follows:
dflm_type dsat707_crm_dflm [] =
{
#ifdef FEATURE_DS_NET_MODEL
{ 0 , 0 , 2 }, /* change to {2, 0, 2} */
#else
{ 0 , 0 , 1 },
