G400E/chan-extra manual

Hi. We need single rack server with fxo/fxs/t1/gsm ports. So we bought some g400e cards for gsm part. I spent two day to adapt chan-extra for asterisk 15 (we allready have code for it and i used unifdef program to cleanout old asterisk version code and attached resulted base.c) and now we have working sms sip <--> gsm gateway and some problems with voice and tty mode. opvxg4xx was successfully compiled against dahdi-linux-complete-2.9.2 but it is crash kernel on modprobe when ttymode is enabled. Is it known problem ?

Also I can make calls and there just no voice at all. Is it chan-extra issue or I should tune some chan parameters ? I just can't find chan-extra 2.0.8 manual - site is not available. Can you give a link to this document ?

Hello，

Sorry about your issue , but as you see now chan_extra only support asterisk 11 and low kernel version , there is no version suitable for asterisk 15 . In my opinion if you want to use G400 card ,Please change the asterisk verison to have a try , By the way this is the link of chan_extra 2.0.8 source code www.openvox.cn/pub/misc/GSM/chan_extra-2.0.8.tar.gz

Best regards

Hi. I tried it with asterisk11 and it doesn't even compiled too. And there is one more issue - we allready have asterisk modules (softmodems) code for asterisk 15 so I desided to adapt it for 15. Anyway i'll try to bring up it on asterisk 15. I allready have src 2.0.8 but it doesn't have manual inside so I have to setup it using source code and this is a pain.

tty issue is very strange:

Oops. I attached opvxg driver source instead of modified chan_extra.c

Hello，

Please downgrade your kernel version to have a try .

Hi. I'll try to fix this error in driver. Last question left - do you have manual for chan-extra 2.0.8 ?
