> Then one peer is slin (L16/8000) or slin16 (L16/16000) and second peer is other codec (tested with ulaw, gsm and speex) slin peer listen only noise. Noise disappear if other peer muted. Slin peer can listen voice if signal is gained down by AGC set to 10 and less (anyway sound is distorted).
> Both peers use sip channel.
> Testes with several peers:
> - slin: MicroSIP 3.10.9, custom HW device
> - other: antiSIP 4.2.9 (Android), SFLphone 1.3.0, Zoiper 3.3.25608
> Asterisk compiled with gcc 4.8.5(FreeBSD) and 4.8.4(Ubuntu).
> On Ubuntu Asterisk compiled with DONT_OPTIMIZE option.
> RTP capture will be attached.
