[asterisk-users] Asterisk + TC400B - Clock Trouble
Hello all, I have a TC400B Digium card in order to deal with transcoding and I have some trouble using it, I have a timer synchronisation problem! I would be very grateful if you have any idea to help me? It seems that the card is not correctly synchronised to the system because when I speak to one side, the sound takes 5 seconds to go to the other side, and increasing, after 30 seconds of call, it takes 25 seconds for the voice to go to the other end... I have Asterisk 1.4.25.1, Dahdi 2.2.0-rc5 on a CentOS-5.3 (x86_64) server with a 2.6.18-128.1.10.el5 linux kernel Ast CLI when calling with g729 ast-01*CLI> transcoder show 1/1 encoders/decoders of 92 channels are in use.

I'm not sure if the kernel timing HZ has anything to still do with things anymore. You might need to recompile your kernel with HZ=1000 -Jon lftsy at leurent.eu wrote:> Hello all, I have a TC400B Digium card in order to deal with > transcoding and I have some trouble using it, I have a timer > synchronisation problem! > I would be very grateful if you have any idea to help me? > > It seems that the card is not correctly synchronised to the system > because when I speak to one side, the sound takes 5 seconds to go to > the other side, and increasing, after 30 seconds of call, it takes 25 > seconds for the voice to go to the other end... > > I have Asterisk 1.4.25.1, Dahdi 2.2.0-rc5 on a CentOS-5.3 > (x86_64) server with a 2.6.18-128.1.10.el5 linux kernel > > > _Ast CLI when calling with g729_ > ast-01*CLI> transcoder show > 1/1 encoders/decoders of 92 channels are in use. > > _Dahdi start returns:_ > (SCREEN):root at ast-01:[~]# /etc/init.d/dahdi start > Loading DAHDI hardware modules: > wctc4xxp: [ OK ] > > No hardware timing source found in /proc/dahdi, loading dahdi_dummy > Running dahdi_cfg: [ OK ] > _DMESG returns:_ > dahdi: Telephony Interface Registered on major 196 > dahdi: Version: 2.2.0-rc5 > dahdi_transcode: Loaded. > wctc4xxp: tc400b0: Attached to device at 0000:0f:03.0. > wctc4xxp: tc400b0: (G.729a / G.723.1) Transcoder support LOADED (firm > ver = 6.12) > wctc4xxp: tc400b0: Installed a Wildcard TC: Wildcard TC400P+TC400M > dahdi_transcode: Registered codec translator 'DTE Encoder' with 92 > transcoders (srcs=0000000c, dsts=00000101) > dahdi_transcode: Registered codec translator 'DTE Decoder' with 92 > transcoders (srcs=00000101, dsts=0000000c) > dahdi: Registered tone zone 30 (Switzerland) > > > -- -- > Marc LEURENT > > -- > Scanned for viruses and dangerous content by *MailScanner* > <http://www.mailscanner.info/> > ------------------------------------------------------------------------ > > _______________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > > asterisk-users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users-- Scanned for viruses and dangerous content by MailScanner
