Ok great. I will do that.

Ok. Agreed.

Yes. I agree.

Ok. I will call my provider again tomorrow and try what you have suggested. Hopefully we get it working! :)
Thank you for all your assistance so far.

Disable one E1 - by not configuring it - as far as dahdi.conf level -

<pre wrap="">You - don't. Your party - provably - has.
If he has - the CIC no 63 that it means for me - it's some misconfiguration.
(Two E1 could take at top - two times 30 - so 60 CIC without any
signaling link, and at least one is a must).
Carefully - setup one E1 - by configuring only one, and double check
the cables and CIC numbering.
