Hi Harald,
I might be wrong but I think that ip.access only supports AMR for
half-rate channels.

Hi Andreas + List,
I have now studied the new "RTP capable" lcr integration in detail. My
sincere apologies once again for the long delay that this has been taking
me.
I really like the interface (like its predecessor). The major restriction
at the moment seems to be its limitation to support only GSM Version 1
Full Rate.
After doing some testing with the current 'lcr_rtp' branch in git, as well
as the attempt to integrate handover support with the lcr/mncc interface,
I am considering to add support for other codec types, too.
GSM EFR (only exists in full-rate) is interesting for everyone, as almost
all phones support it, and it renders significantly higher quality.
GSM V1 halfrate is important for BS-11 users who want increased capacity, since
this BTS does not support AMR-halfrate.
GSM V1 full-rate is important for ip.access, since it is the only half-rate
codec it supports, and thus the only way to increase capacity for this BTS.
GSM AMR full-rate is probably of the least interest, but still nice to have.
For the 26C3, I would love to run in a EFR-fullrate and AMR-halfrate
configuration, depending on the phone's capabilities.
Regards,
Harald
