Hi,

I have a question about point code. When I install a sangoma card, there weren't any step require me to configure point code. 

I thin when telco provide us E1 lines, MSC will configure to forward calles through the E1 lines to my Asterisk ?.

Please point me how can I configure point code for Asterisk. Do I have to config Sangoma Card ? 

Thanks.

Hi there,

ISDN is not a protocol. See 
http://en.wikipedia.org/wiki/Integrated_Services_Digital_Network#Internationale_Verbreitung 
for more details. As far as I know Vietnam uses DSS1 (Euro-ISDN).

The benefit of SS7 is that you can use a single signaling channel 
(D-Chan) for more E1s. I have 8 E1s with a single D-Chan at our site. 
Using DSS1 you have one D-Chan for one E1. From signaling point of view 
there is no gain if you just need one E1.

If you want to have a interconnection with that GSM telco you need a 
point code from  them and then configure your Asterisk box properly to 
receive calls.

I will fly to Vietnam next month. If you want to just feel free to email 
me. Maybe I can give you a helping hand there.
