Guys,
I am having this issue and i just need to verify, or justify to the telco that my configs are correct and the issue is maybe a loop on their switching
i've tried changing isdn switch-type and related configs to primary-net5 as this is E1, but no changes.
the debugs just show bad frames, i have been following this post as well. Any assistance i can get i will appreciate thanks

Ask telco to revise their config, because it seems like they're set user-side.

Hi Alex,
thanks for your quick response, think maybe i confused everyone...
The service provider is using isdn switch-type primary-qsig its why i have qsig in the configs.
what i was trying to say is that i also reconfigured with the configs you posted as well but it didnt work either.
however if you think of anything else i would appreciate..thanks a mil..
thanks for your greeting,
Hope you also have a wonderful holiday Season! All best wishes to you and yours

thanks everyone, the problem was definitely on the service provider's end once they resolved it came up fine
