I’m getting this error when making a sip call from the zap channel.
sip_write: Asked to transmit frame type 4, while native formats is 256 (read/write = 256/256)
May 25 15:09:59 WARNING: chan_zap.c:4715 zt_write: Cannot handle frames in 256 format
what does it mean and how can I correct it?
Thanks in advance,
