Have you bought G.729a from Digium which cost $10/channel? At 02:04 25/12/03 +0300, you wrote:
Hello, I've successfully installed Asterisk from last CVS and configured it for using with DLINK-DG104S as mgcp CPE and PGW2200 as external sip server. All are work fine at G711 codecs, but then I disable all codecs except g729 some calls failed (Not all calls. Some calls passed at g729 succesfully). All my devices configred to use only g729 and I don't see other codecs at mgcp or sip messages, but I see strange string at asterisks log:
NOTICE[196633]: File rtp.c, Line 418 (ast_rtp_read): Unknown RTP codec 123 received NOTICE[196633]: File channel.c, Line 1478 (ast_set_read_format): Unable to find a path from ALAW to G729A NOTICE[196633]: File channel.c, Line 1448 (ast_set_write_format): Unable to find a path from G729A to ALAW WARNING[196633]: File chan_mgcp.c, Line 757 (mgcp_write): Asked to transmit frame type 8, while native formats is 256 (read/write = 256/256) WARNING[196633]: File app_dial.c, Line 279 (wait_for_answer): Unable to forward frame
I find similary posts at Asteris-Users mailing list, but don't find how to resolve this trouble. Is this a bug or some misconfiguration at my configs ?
sip.conf: [general] port = 5060 bindaddr = 0.0.0.0 context = local disallow = all allow = g729 mgcp.conf [general] port = 2427 bindaddr = 0.0.0.0 disallow = all allow = g729 [DLINK] context=local host=Y.Y.Y.Y threewaycalling=yes transfer=yes line => aaln/1 line => aaln/2 line => aaln/3 line => aaln/4 extension.conf [local] ignorepat => 9 exten => _9XXXXXXX,1,Dial,SIP/${EXTEN:[EMAIL PROTECTED]
Some logs from Asterisk:
First mgcp CRCX after hang up: Posting Request: CRCX 323 aaln/[EMAIL PROTECTED] MGCP 1.0 v=0 o=root 23577 23577 IN IP4 X.X.X.X s=session c=IN IP4 X.X.X.X t=0 0 m=audio 14548 RTP/AVP 18 a=rtpmap:18 G729/8000
After that I enter phone number and sent call to sip server:
-- Executing Dial("MGCP/aaln/[EMAIL PROTECTED]", "SIP/[EMAIL PROTECTED]") in new stack

Then I receive reply from SIP server: Sip read: SIP/2.0 100 Trying <skip>

After this message sometimes Asterisk make error message at log and drop call:
