Calls not working from Nortel Meridian to Asterisk

Asterisk Asterisk Support

Hi, i just integrated an asterisk with a Meridian OP 81 C using ISDN:

Calls from Asterisk to Meridian= OK working
[color=red]Calls from Meridian to Asterisk = Not Working[/color]
Calls to PSTN from asterisk using M1 trunks = OK

Anyone know How do i configure the routes/dialplan to work incoming calls from M1 to Asterisk PBX???

Thanks!

What do the Asterisk logs show when you try calling from the Meridian?

I’ve integrated an option11c with an asterisk using a PRI.

The option11c requires an update to the CDP in order to route calls to extension numbers homes on the asterisk
