[Asterisk-Users] analog gsm router

[Altus Snyman]

Good day all
I have a analog gsm router and a 4 port bri card:-)
How do I get the gsm router to work with asterisk
I tried adding a voicetronix card but the 2 cards doen not seem to work
together,it gives a unresolved symbols error when starting up
Any Ideas Please
Can you add 2 zaptel device,different ones?
Like the Junghannes and a diguim analog card?
Please help and advice
Thanks
