Some of the settings are also available in GVC3200/GVC3202 LCD display 🡺 Settings 🡺 Accounts: select Blue Jeans as the account.

Figure 18: Access Blue Jeans Settings in Web UI

The following table lists all Blue Jeans settings available on GVC3200/GVC3202 web UI. For more detailed information about how to access and use GVC3200/GVC3202 web UI, please refer to GVC3200/GVC3202 user manuals in http://www.grandstream.com/support.

Parameters	Descriptions
General
Display Name	It is used to configure the SIP server subscriber’s name (optional) that will be used for Caller ID display. The configured content will be included in the From, Contact and P-Preferred-Identity headers of SIP INVITE message.
Codec
DTMF	It is used to set the parameter to specify the mechanism to transmit DTMF (Dual Tone Multi-Frequency) signals. There are 3 supported modes: in audio, RFC2833, or SIP INFO. In audio DTMF is combined in the audio signal (not very reliable with low-bit-rate codecs). RFC2833 Specify DTMF with RTP packet. Users could know the packet is DTMF in the RTP header as well as the type of DTMF. SIP INFO Use SIP INFO to carry DTMF. The disadvantage of this mode is that it’s easy to cause desynchronized of DTMF and media packet if the SIP and RTP messages are required to transmitted respectively. The default setting is “RFC2833”.
DTMF Payload Type	It is used to configure the RTP payload type that indicates the transmitted packet contains DTMF digits. The valid range is from 96 to 127. The default setting is “101”.
Preferred Vocoder	It lists the available and enabled audio codecs for this account. Users can enable the specific audio codecs by moving them to the Selected box and set them with a priority order from top to bottom. This configuration will be included with the same preference order in the SIP SDP message. The codec option includes “PCMU”, “PCMA”, “Opus”, “G.722”, and “G.722.1”.


Codec Negotiation Priority	It is used to configure the codec negotiation sequence when the GVC3200/GVC3202 is acted as a callee. If set to “Caller”, the device will negotiate codec by SDP codec sequence from the received SIP INVITE message. If set to “Callee”, the device will negotiate codec according to the codec priority configuration on the device itself. The default setting is “Callee”.
Silence Suppression	It is used to set the silence suppression/VAD feature. If it is set to “Yes”, when silence is detected, a small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. If set to “No”, this feature is disabled. The default setting is “No”.
Voice Frames Per TX	It should be noted that the “ptime” value for the SDP will change with different configurations here. This value is related to the codec used and the actual frames transmitted during the in payload call. e.g.: if set to 2 and the first codec is G.729, G.711 or G.726, the “ptime” value is 20ms for the SDP. If the TX exceeds the maximum allowable value, the device will use and save the maximum allowed value according to what the first codec is. For end users, it is recommended to use the default setting, as incorrect settings may influence the audio quality. The default setting is “2”.
G.722.1 Rate	It is used to select encoding rate for G.722.1 codec. It supports 24kbps or 32kbps. The default setting is “24kbps encoding rate”.
G.722.1 Payload Type	It is used to configure payload type for G.722.1 codec. The valid range is 100-126. The default setting is “104”.
Opus Payload Type	It is used to configure payload type for Opus codec. The valid range is 96-126. The default setting is “123”.
Use First Matching Vocoder in 200OK SDP	If set to “Yes”, the device will use the first matching vocoder in the sent 200OK SDP as the codec. The default setting is “No”.
Enable RFC5168 Support	If set to “Yes”, the RFC5168 mechanism will be enabled for video call. RFC5168 allows SIP party to request the sender to refresh its video frame in H.264, or refresh the full picture in VP8. The default setting is “Yes”.
Enable Video FEC	If enabled, the video sender will temporarily allocate part of the bandwidth to one data channel to send FEC data to system, thus to improve the video quality the receiver gets. Enabling this function will take up part of bandwidth and reduce call rate. The default setting is “Yes”.
FEC Payload Type	It is used to configure FEC payload type. The range is 96-127. The default setting is 120.
FEC RED Payload Type	It is used to configure FEC RED payload type. The valid range is from 96 to 127. The default value is 122.


H.264 Payload Type	It is used to configure the H.264 codec message payload type format. The default setting is 99. The valid range is from 96 to 127.
H.264 Image Size	It is used to set the H.264 image size. It can be selected from the dropdown list. 1080P 720P 4CIF 4SIF VGA The default setting is 1080P.
H.264 Profile Type	It is used to set the H.264 profile type. It can be selected from the dropdown list. Baseline Profile Main Profile High Profile BP&MP&HP The default setting is “BP&MP&HP”. Lower profile is easier to decode while higher profile provides higher compression ratio. For device with low CPU, select “Baseline Profile”. Also, “Baseline Profile” is likely to be used in a video conference that has high demanding for the video quality.
Video Bit Rate	It is used to configure the bit rate of the video device. The default setting is 2048kpbs. It is recommended to increase bit rate if bandwidth allows. If the bandwidth is not enough, the video quality will be reduced. H.264 Image Size = 1080p, the Video Bit Rate can be set to an integer value from 2048kbps to 4096kbps. H.264 Image Size = 720p, the Video Bit Rate can be set to an integer value from 1024kbps to 2048kbps. H.264 Image Size = 4SIF/4CIF/VGA, the Video Bit Rate can be set to an integer value from 384 to 1024 Kbps.


SDP Bandwidth Attribute	Select the SDP bandwidth attribute from “Standard”, “Media Level” or “None”. Standard: Use AS at the session level and TIAS at the media level. Media Level: Use AS at the media level. None: Do not change the format. The default setting is “Media Level”. Note: Please do not change the format as it may cause decode failure if the user is unclear about what format the server supports.
Video Frame Rate	Configures the frame rate for SIP video call. The default is 30 fps. Increase frame rate will take up bandwidth; the video quality will be reduced if not allocated enough bandwidth.
Video Jitter Buffer Maximum (ms)	Configures the video buffer size according to the network environment. The valid range is 0-1000, the default setting is 50.
Disable Presentation	If set to “Yes”, the device will disable presentation and will not receive presentation during video call. The default setting is “No”.
Presentation H.264 Image Size	It is used to select the H.264 image size from “720P” or “1080P”. The default setting is “1080P”.
Presentation H.264 Profile Type	Select the H.264 profile type from “Baseline Profile”, “Main Profile”, “High Profile” or “BP&MP&HP”. The default setting is “BP&MP&HP”. Lower profile type is easier to decode, while higher level has higher compression ratio. For device with low CPU, select “Baseline Profile”. Also, “Baseline Profile” is likely to be used in a video conference that has high demand for the video quality.
Presentation Video Bit Rate	Configures the bit rate of the video. The video bit rate can be adjusted based on the network environment. Increasing the video bit rate may improve video quality if the bandwidth is permitted. If the bandwidth is not permitted, the video quality will decrease due to packet loss. The default setting depends on presentation H.264 image size. Presentation H.264 Image Size = 1080p, Video Bit Rate can be set to an integer value from 1024kbps to 4096kbps Presentation H.264 Image Size = 720p, Video Bit Rate can be set to an integer value from 512kbps to 2048kbps
Presentation Video Frame Rate	Configures the video frame rate for presentation. The options are 5fps, 10fps and 15fps. The default setting is 15fps.

Call
Call Log	It is used to categorize the call logs saved for this account. If it is set to “Log All”, all the call logs of this account will be saved. If set to Log Incoming/Outgoing Calls (Missed Calls Not Record), the whole call history will be saved other than missed call. If it set to Disable Call All, none of the call history will be saved. The default setting is “Log All”.
Use # as Dial Key	It is used to set the device whether to use the “#” key as the “Send” key. If set to “Yes”, if the end user taps the “#” key on the remote control, the device will send out the typed digits. If set to “No”, the “#” key is included as part of the dialing string and please make sure the dial plan is properly configured to allow dialing # out. The default setting is “Yes”.
Upload Local MOH Audio File	It is used to load the MOH (Music on Hold) file to the device. Click on “Browse” button to upload the music file from local PC. The MOH audio file has to be in .wav or .mp3 format. Note: Please be patient while the audio file is being uploaded. It could take more than 3 minutes to finish the uploading especially the file size is large. The button will show as “Processing” during the uploading. Once done, it will show as “Browse” again. Click on “Save” on the bottom of the web page and “Apply” on the top of the web page to save the change.
Enable Local MOH	If set to “Yes”, the local MOH will be enabled. Users need to upload local MOH audio file. Once enabled, users could play the file when holding the call. The default setting is “No”.
