[asterisk-users] special control 16

[Nick Ustinov]

Hi

What is special control 16?


I am getting this error quite often --

special control 16, then for some reason it puts on hold and then logs is full of Asked to transmit frame type ulaw, while native formats is 0x8 (alaw) read/write = 0x8 (alaw)/0x8 (alaw)

Both peer and trunk have same codec priority (disallow=all then allow=alaw then alllow=ulaw)


Any ideas how to fix this ?
