Hi, james, I have managed to install B410P card with misdn driver with asterisk 1.2.24.

However I am not sure how to configure the misdn driver. I notice that for Digium card they start misdn driver by /etc/init.d/misdn-init scan/config/start. and they have files in /etc/init.d/misdn-init.conf

But for Openvox B410p card we use /usr/sbin/mISDN scan/config/start, and we have files in /etc/mISDN.conf.

Can you tell me the difference or either of them is fine to fun?

and could you also post the files /etc/asterisk/misdn.conf for Openvox B410p card?

thanks in advance.

hello, you have to replace the hfc_multi.c for B400P. the mISDN is mISDN-1_1-2. you run the mISDN scan, mISDN config and mISDN start. it will generate mISDN.conf for you. the conf is shown in the user manual( www.openvox.com.cn/downloadsFile/1193650142.pdf ). you also can refer with misdn.org.
Regards!

hi, james, thank you for your fast response, your support is really good. After applying the patch and installing misdn driver, I have made a mistake and apply /etc/init.d/misdn-init scan/config/start.

After that I notice it's not for B400P card, so I apply mISDN /scan/config/start, again. Does it matter?

Below is my server /etc/asterisk/misdn.conf/. could you please check for me:

Hi, James, Thank you so much for your fast response.
I have done some tests over the server and I always encounter one issue with misdn driver:
I can make both incoming and outgoing calls without any problem. The call quality is good, and there is no echo and other troublesome problem.

However, There is one problem for incoming call to voicemail (no one pickup or not registered), then I will have below errors, with this error if I try to make outgoing call again, I can call through but no sound passing through:
kernel: mISDN_rdata: rport queue overflow 256/256 [addr:52010101 prim:120282 dinfo]
kernel: mISDN_rdata: rport queue overflow 256/256 [addr:52010101 prim:120282 dinfo]
kernel: mISDN_rdata: rport queue overflow 256/256 [addr:52010101 prim:120282 dinfo]

Any idea?
I will provide any other information you want to check.
