Hello,

I had similar problem and I think it is more a problem between Sangoma card and your E1 provider than with freeswitch.

In my case it was necessary to set "origination_caller_id_number" to one of the telephone numbers linked to my E1 line. In other case the calls were rejected with "invalid information element" error.

You can try Sangoma's support they are very helpful.

In the Dchan log it is saying Invalid Information Elements. That might be a problem??? But I even don't know why it is saying Invalid Information Element??
Please guide me!!!
