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

[Mc GRATH Ricardo]

It seems a layer 2 problem, should check about references point (network or terminal equipment), it assume your Asterisk box is connected to ISDN PSTN provided, just in case check  at you side if all related configuration files are configured as signalling=pri_cpe  (Card config, wan_cfg, chan_dahdi.conf), PSTN side if network configuration or in service mode, should  both side work and debug in the same time.
