Telephone Accessories User Manual

IP addressing can be done statically or dynamically, as explained in the Cisco ATA 186 Basic
Configuration document. In the previous screen, the static IP address is used.
In the Cisco ATA 186 Configuration window, configure these fields:
UID0 and UID1Configure the E.164 addresses of voice ports 0 and 1.
Both voice ports can not have the same E.164 address, as the ATA 186 can not hunt if one of
the ports is busy. If both voice ports are assigned the same E.164 address, the call will always
be sent to the first voice port. If this port is busy, the busy signal is sent to the caller.
♦
RxCodec and TxCodecConfigure the codec ID.
G.723.1codec ID 0.◊
G.711acodec ID 1.◊
G.711ucodec ID 2.◊
G.729acodec ID 3.◊
In the configuration shown below, the G.729r8 codec is used on the ATA 186 and on the
gateway.
♦
LBRCodecConfigure as 0 or 3, based on the chosen codec.
LBRC is 0G.723.1 codec is available to both FXS ports at any time. Each line can
maintain two G.723.1 calls in a non−conference state. Therefore, up to four G.723.1
calls can be maintained in the Cisco ATA 186. An example is call waiting.
◊
LBRC is 3G.729a is available to one of the two FXS ports on a
first−come−first−served basis. If the Cisco IOS gateway is configured with the
default G.729 codec, only one ATA 186 port can be used. To prevent the second call
from failing, configure a voice codec−class on the gateway to negotiate the second
call using a G.711 codec. For detailed information, refer to the Codec Negotiation
section of the Understanding Codecs: Complexity, Hardware Support, MOS, and
Negotiation document.
