Hi,

Does anybody have the signification of this debug information:
‘3 !! Unknown IE 36 (cs6, Unknown Information Element) ?’

Thanks for reply,

Hy,

It depends on the context. It appears on ISDN calls and means that * does not recognize the information element received from the other isdn party.

Maybe we can tell you more if you post all debug information on this post.

Mircea.
