Voice Rate +WVR
Multi-Tech Systems, Inc. GPRS AT Commands Reference Guide (Document Number S000293J)
Description:
Values:
Command syntax: AT+WVR=
This command allows the voice rate for bearer voice to be configured for outgoing and incoming calls.
Note: According to the modem’s capabilities, the following voice coding type are allowed:
Voice coding type.
Voice Coding
AT+WVR=
AT+WVR?
Note: <out_coding_type> is related to outgoing calls; <in-coding_type> to incoming calls.
AT+WVR=1
Note: Configure voice type FR and EFR
for outgoing calls only
AT+WVR=1,4
AT+WVR=,4
Command
Note: Configure voice type FR and EFR
for outgoing calls and HR and EFR for
incoming calls
