Hi everyone
Recently, SX20 has interoperated with 3rd SIP server & MCU
register & Connection was done , But it has a problem about video quality
The symptom is that Video packet loss has continued generated from MCU to SX20 (Network status is fine , Several times check )
At that time SX20 generated log messages as below:
Jan 1 11:06:19 a8 vcodec: GDR_handleDecoderResult: GDR received
Jan 1 11:06:21 a8 vcodec: GDR_handleDecoderResult: GDR received

Jan 1 11:06:28 a8 vcodec: GDR_handleDecoderResult: GDR received
Jan 1 11:06:30 a8 vcodec: GDR_handleDecoderResult: GDR received
Does anyone explain to me log messages mean. ?
(please refer to attached file. SX20 version is TC 6.1.1)

Firstly, I'd recommend that you upgrade the software version on your SX20 as TC6.1.1 is vulnerable to the Heartbleed OpenSSL Security Vulnerability (you need TC6.3.1 or TC7.1.1 to be safe).
With regard to your error - what bandwidth are you making the call at? Does the video quality improve (and get less errors) if you lower the bandwidth?
