Hi Harald,

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

Roch.

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
