Comments:	By: heison (heison) 2004-03-19 16:34:13.000-0600 need more info. - what version * are you running? - does it work when you're using 711 on both sides? By: sbingner (sbingner) 2004-03-19 23:04:27.000-0600 G.711 worked on both sides, and I was using the CVS version current at the time I posted the bug.  Unfortunately my ATA is elsewhere so I can't test it again right now. By: sbingner (sbingner) 2004-03-20 20:03:26.000-0600 I encountered the same problem from zap channels if I call the ATA; I don't hear anything from the ATA but I can hear everything from the zap side on the ATA -- it seems like the IAXy tries to send data as ULAW, even though I disabled it in the iaxy.config Mar 20 14:48:36 NOTICE[1217669936]: channel.c:1159 ast_read: Dropping incompatible voice frame on IAX2[iaxy]/2 of format ULAW since our native format has changed to ADPCM Mar 20 14:48:36 NOTICE[1217669936]: channel.c:1159 ast_read: Dropping incompatible voice frame on IAX2[iaxy]/2 of format ULAW since our native format has changed to ADPCM This is with the current CVS, and it works fine if I select ULAW on the IAXy By: lancey (lancey) 2004-03-20 20:08:37.000-0600 Cisco ATA? G.726???? You sure??? By: sbingner (sbingner) 2004-03-20 20:14:18.000-0600 Are you asking if the Cisco ATA supports g.726?   If so, then your answer is yes, it does and yes, I'm sure. By: lancey (lancey) 2004-03-20 20:22:12.000-0600 What is the appropriate RX/TX code for G.726? If it does support it, it might have been added in 3.0 firmware. Is that right? By: sbingner (sbingner) 2004-03-20 20:25:53.000-0600 I don't know if it was added in the 3 firmware but it is possible.  If you want info on it, talk to me in IRC - my nick is Death_INC, this isn't the place for a conversation Parameter info below: # ----------------------------------------------------------------------------- #   Parameter:  RxCodec # Access Code:  36 #  Value type:  Integer  (0 - 3) # # Description:  Receiving audio codec preference #       #     Options:  0 = G.723.1 (can be selected only if LBRCodec is set to 0) #               1 = G.711a #              *2 = G.711u #               3 = G.729a  (can be selected only if LBRCodec is set to 3) #               6 = G.726-32kbps By: heison (heison) 2004-03-21 18:13:39.000-0600 problem fixed when only one codec is allowed in iax.conf: e.g. [iaxy] host=dynamic disallow=all ;allow=ulaw allow=adpcm type=friend secret=password qualify=yes context=zeal
