How to obtain and handle GSM_EVENT_SM_RECEIVED in dialplan

Hi, We've developed another newer driver named chan-extra for G400P, you will be able to store, send and receive SMS. There is a hint on the asterisk CLI when you receive a short message. So is it possible to switch to this driver from bristuff?

Please read here for more.

Thank you for your quick response.But I think it's impractical to keep watching the asterisk CLI and waiting for the SMS incoming.I want to obtain and handle the SMS event automatically.

Is there any programing method like dialplan to achieve my goal if I switch to chan-extra? When asterisk receives a short message, except the hint on asterisk CLI,is there any other way to get informed of this event? I have a little knowledge of AGI and AMI,can this two interfaces help?

Hi,
Our driver chan_extra owns "GSM_EVENT_SMS_RECEIVED" case in chan_extra.c . Unfortunately, we don't have this kind of material of how to make it worked , but I've googled and got that there is a possible method like this:AIM event triggering an incoming SMS message. Here its link: http://forum.pikatechnologies.com/showthread.php?547-Send-and-Receive-SMS

I hope this would help you.

You are very kind and patient,thank you!I have viewed the web page,it seems that they are using a channel driver named chan_gsm,and I can't find it in opvx-bristuff-0.4.0-RC3h. So I can't use the commands like "[font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif]gsm show sms [/font]" and "[font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif]gsm fetch sms [/font]".Furthermore,the methods introduced in the web page all ends with manually fetching SMS by CLI command [font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif] 'gsm fetch sms' [/font].

I have tried to modify chan_dahdi.c to add some code under case GSM-EVENT_SM_RECEIVED,then I run opvx-bristuff-0.4.0-RC3h/compile.sh. After it completed,the modified chan_dahdi.c was covered , and it turned to be the original one.I think it must be coverd during the compile procedure,but I have poor knowledge of makefile , would you please tell me how can I modify chan_dahdi.c and re-compile opvx-bristuff-0.4.0-RC3h to add the functions I need?

I just tried to switch to chan_extra
Because I have already installed and run opvx-bristuff-0.4.0-RC3h,so I first stop asterisk gracefully from asterisk CLI ,then 'rmmod opvxg4xx' and 'rmmod zaptel'.
For the purpose of insurance, I enter /usr/src/opvx-bristuff-0.4.0-RC3h/asterisk-1.4.26.2 and run 'make uninstall' to remove asterisk-1.4.26.2
enter /usr/src/opvx-bristuff-0.4.0-RC3h/zaptel and run 'make uninstall-modules' to remove zaptel
After that, I successfully install chan_extra-1.1.0 by running /usr/src/chan_extra-1.1.0 /install.sh
Then I run 'service dahdi start' , 'depmod –a' , 'dahdi_genconf' , 'dahdi_cfg –vv' , 'dmesg' one by one, and dmesg gave the following information:

=============================

What I can confirm is that the SIM is correctly inserted into G400P , because when I switch back to opvx-bristuff-0.4.0-RC3h it works fine. So it must be software problems. But I just followed the guidance in http://www.chan-extra.org/index.php/OpenVox_G400P_User_Manual_for_dahdi ,can you give some advices? Thank you very very much.

Yes, the chan-extra would inform you SIM not inserted if you are not fully using all the modules.

From your post, I found that you only used two of them, right?. So, to disable the errors on the asterisk CLI, please forward to /etc/asterisk/extra-channels.conf, then disable the channels you are not using(Span3 and Span 4?).
