OpenR2

Introduction 

We have integrated "OpenR2" stack into All the Next Gen Digital VEGA for handling R2 protocol.

OpenR2 VEGA support would be available on/after  "R11.0 S021" release dated on 3rd Oct 2016. 

OpenR2 Vega Configuration

VEGA GUI -> E1T1-> ISDN section R2 configuration  - 

All the parameters as mentioned below are commonly used OpenR2 parameters when we run asterisk with OpenR2.

Please refer to below wiki for details of OpenR2 configuration parameters.

Quick Configuration

OpenR2 Vega Cli commands

Please find below list of cli commands -

MFCR2 SET BLOCK <port> <channel> Reset MFC/R2 channel forcing it to BLOCKED

MFCR2 SET BLOCK <port> ALL    Reset ALL MFC/R2 channel forcing it to BLOCKED

MFCR2 SET IDLE <port> <channel> Reset MFC/R2 channel forcing it to IDLE

MFCR2 SET IDLE <port> ALL     Reset ALL MFC/R2 channel forcing it to IDLE

MFCR2 SHOW CHANNELS <port>    Show MFC/R2 channels

MFCR2 SHOW VERSION            Show OpenR2 library version

OpenR2 Vega Advanced configuration  

We can have option to upload advanced r2 protocol configuration file in VEGA for OpenR2 stack.

WARNING: advanced users only as it allows you custom define tone definitions used in the protocol! 

Ref: MFCR2 Configuration

We can download default/existing r2proto.conf file from VEGA and then after modification same can be uploaded back to VEGA.

Please note that new r2 protocol configuration file will take effect only after rebooting vega.

OpenR2 Vega logging 

All the logging as mentioned in below wiki page to capture R2 logs will also be applicable to OpenR2 supported VEGA firmware.

Vega Gateways Home 

Please note - If issue is happening on 1 call itself then it would be nice to capture detail logs of CAS/ISDN module as mentioned below -

debug enable router rs
debug enable isdn rs
debug enable _cas ietf1234567

debug enable _isdn ietf1234567

debug enable _logger i
sip monitor on
log display off
debug on

OpenR2 Vega log analysis

All the CAS logs are prefixed with [sXcY] keyword where X is port number and Y is channel number.

Logs prefixed with "R2-DSL" is coming from the OpenR2 stack.

We can always filter the logs based on "R2-DSL" and  "[sXcY] " to get the OpenR2 stack logs for X port and Y channel call.
