Hello, Does asterisk do transcoding when the call goes through the system, codecs are the same but signaling protocol is changed. example: SIP with GSM ---> IAX with GSM What quality destruction happen when I use transcoding? I know this is not a concrete/precise question, but I would like to know how is it in general. What CPU performance is needed for transcoding 30 channels e.g. from

Hello all, I've got an AVM Fritz!Card PCI that I'm using with Asterisk under chan_capi (0.3.5) Phones on our internal network all use g711u. I'm aware the chan_capi uses g711a by default. To reduce the need for transcoding, I decided to make everything use the same codec. First I changed all the phones (Cisco models 7905G, 7940G and ATA 186 all running SIP) to g711a, but it seemed

Hello, I'd like to ask whether there is some documentation with recommended parameters for transcoding voice codecs such as G722, G711a/u <-> Opus with near-transparency. My Idea is to have something like: HW-Phone <-> Asterisk <---------> Asterisk <-> HW-Phone (G722) (Opus) (G722) in order to lower the bandwidth between the two

Hi, I am using the Grandstream HandyTone 486 as a SIP Adapter with a regular phone. Asterisk configuration is listed below. When I attempt to place a H.323 call, I receive the following errors: - Executing Dial("SIP/2000-3029", "OH323/##########@xxx.xxx.xxx.xx:1720|20") in new stack Aug 13 09:13:03 WARNING[20497]: channel.c:1806 ast_request: No translator path exists

I had unexpected hangups from my asterix box using the i4l driver. (SIP <-> SIP calls worked execellent, but SIP<->ISDN didn't.) Then I changed the i4l driver in modem.conf with the chan_capi from jungham. (http://www.junghanns.net/asterisk) I followed his instructions in the INSTALL file, and first encountered some errors compiling it. It help by deinstalling several

I'm trying to compile chan_capi-0.5.4 on Slackware 10, but I have bunch of errors. (By the way, can I use chan_capi for ISDN card with winbond w6692cf chipset?) I'm not a linux expert, still :-) Before compiling, when I type "modprobe capi" to load capi module, and then "lsmod", i get list of modules: capi 6208 0 kernelcapi 30496 1

hi all, i have a probably very stupid question/problem. for testing purpose i am trying to get asterisk running with two isdn cards. I'd only like to here the demo sound when i call the number - but nothing works. The output of show channels is not showing any channel - should there be 4 channels ? - capi info shows my two cards perfectly. The ISDN Controller's are attached to an PTMP

Hello all, I'm trying to get CAPI to work with two B channels (AVM B1 PCMCIA) on a P4 2GHz (linux kernel 2.4.21) system. All are ok with just one B channel. But when I open a second B chan, the sound is choppy, with too long gaps, and the CPU load is too high (~50%). On the Asterisk's console I get these messages: -- Executing Dial("H323:4478",

Hi list, Does chan_capi work with kernel 2.6? The Eicon Diva server card loads fine judging from /var/log/messages but Asterisk gives an error when trying to load the chan_capi module.
