[asterisk-users] PRI Error on span 1: Received MDL/TEI management message, but configured for mode other than PTMP

Eric,

since you seem to have a Sangoma card, you should contact Sangoma's excellent technical support. 
I'll have a look at your pcap trace tomorrow. You can also download the relevant Q.931 and Q.921 
docs from ITU's web server.

Sangoma's wanpipe drivers allow you to configure a few hardware things. Can you post the config 
of one of your spans?

Besides this, what is your libpri version?  Maybe this relates to your problem
