Description
In osmo-mgw, there is this VTY cfg option
sdp audio fmtp-extra .NAMEI cannot find any proper documentation for it, but it seems the intended usage is
sdp audio fmtp-extra a=fmtp:112 octet-align=1and there is code that adds this "a=fmtp:112 octet-align=1" line to all SDP output.
This code adds complexity:
- parsing the cfg string for the PT nr (112 in above example)
- inserting this fmtp-extra to any other fmtp string that may be defined for that PT nr, and doing so wrongly
I think that we should drop it.
'fmtp-extra' was added in 5ea1bc77a3947f541d576f95e7ecc7249fc65b9b (apparently from openbsc.git history) with commit log:
mgcp: Allow to freely control the a=fmtp line for experiments In case of AMR one can specify the available codecs out-of-band. Allow to configure this line statically in the configuration file.
Does this 'fmtp-extra' vty option have any user relevance today?
I'd like to drop that feature and shift all fmtp composition to the MGCP clients, where it belongs.
