[Asterisk-Users] Grandstream ATA 486 works only with ulaw and alaw codecs.
Does anybody has got the some problem? The grandstream ATA 486 schould support almost all codecs, but it doesn't work. I get the following message when I force the use of different codec WARNING[9529]: chan_sip.c:2765 process_sdp: No compatible codecs! Feb 3 11:17:15 NOTICE[9529]: chan_sip.c:7395 handle_request: Unable to create/find channel What could I do to see some more detailed logs? My sip.conf [p1] type=friend username=p1 fromuser=p1 dtmfmode=rfc2833;info;inband;info;rfc2833 ;inband info http://www.voip-info.org/wiki-Asterisk secrethost=dynamic amaflags=default ; Choices are default, omit, billing, documentation allow=all I was trying to change almost anything. In the granstream configuration webpage are the following things to configure, I don't understend, maybe it could do that tric. G723 rate: 6.3kbps encoding rate 5.3kbps encoding rate // tried both iLBC frame size: 20ms 30ms // 20 ms iLBC payload type: (between 96 and 127, default is 98) //98 Silence Suppression: No Yes Voice Frames per TX: 2 (up to 10/20/32/64 for G711/G726/G723/other codecs respectively) // did not try Layer 3 QoS: (Diff-Serv or Precedence value) // 48 Layer 2 QoS: 802.1Q/VLAN Tag 802.1p priority value (0-7) /0 0 I'm using the 1.0.5.16 firmaware, and was using the buggy 1.0.5.21 My asterisk is working fine with about 8 SIP and IAX2 providers using any codecs ... (also the 723) I'm using about 1 month old Asterisk from the CVS. Any comments would be appreciated.
Possibly Parallel Threads
- sip.conf codecs: ulaw, alaw and g729
- Use the NEW ulaw/alaw codecs (slower, but cleaner)
- I can do alaw, ulaw and gsm; remote can do g729 and alaw; asterisk wants to translate g729 -> alaw. WHY?
- I can do alaw, ulaw and gsm; remote can do g729 and alaw; asterisk wants to translate g729 -> alaw. WHY?
- Asked to transmit frame type slin, while native formats is 0x8 (alaw) read/write = 0x4 (ulaw)/0x8 (alaw)
