<br>Asterisk 1.8.3.2<br><br>I have been getting this warning constantly on CLI in a call scenario where I use local channels to connect SIP with PSTN. <br>I use callfile and local channel to first call a PSTN number and if answered, use local channel to call SIP phone with music on hold enabled in Dial string.<br>
If I call PSTN from SIP directly or vice versa I don't see this warning coming.<br>On SIP I have allowed only one codec(alaw).<br><br>[Jun 28 15:05:00] WARNING[31016] chan_sip.c: Asked to transmit frame type slin, while native formats is 0x8 (alaw) read/write = 0x8 (alaw)/0x8 (alaw)<br>
<br><br>I also tried to yes/no option transcode_via_sln in asterisk.conf without any success.<br>Any idea?<br>Thanks,<br>--AM<br>
