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

My recent experiences with Sangoma tech support have been less than good.     I admit the issue was rather wieid.  We had an issue about a year ago where Sangoma PCI cards would not work in the servers we were purchasing unless you used a PCI/PCI-X converter/riser card.   Everything would load but card would not work.   On analog cards, the ports stayed red even after pluggin lines, on PRIs the span would appear to come up, but no interrupts were seen on the card.  After 2 weeks of Sangoma blaming the circuit I finally gave up and ordered riser cards for all our remaining PCI Sangoma cards.   Once all the older PCI cards were used from stock we started using PCI-X cards and didn't have the problem again.

We will be rebooting the server after hours, if that doesn't fix it, I'll update to a recent DAHDI, latest libpri, latest wanpipe, and latest Asterisk 1.4.x and see if the issue continues.   I suspect a change on the telco side, but I can't prove it.

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
