Hi Scott, thanks for the reply, but I already tried what you suggested: no mgcp/mgcp removed the original 'TEI ASSIGNED' indication, I've also reset the GW on the CCM, but with no results (the 'test' dial-peer 999 was removed too). That was why I was thinking about a missing command somewhere. I suppose - as it's all ISDN related signaling - having a connection NM-HDV2 to NM-HDV shouldn't cause any problem? Either way, I've put back the NM-HDV instead of the NM-HDV2, and everything was working again... gonna keep it like that now, and if I find some extra time, I'll have another look at it - but Thank You for the help! Kind regards, Juan

Then do a 'no mgcp' then 'mgcp' - Maybe reset the gateway on CCM as well and you should be good to go.

I had a working MGCP GW, connected via PRI to the PSTN. When using the NM-HDV2, I expercience a L2 issue (see debug below), causing all calls over that PRI to fail. I doubt that the HW is broken in this case, and it's a matter of a missing command... Does anybody have a clue or experienced the same - please let me know. I attached the config used on the GW - it's functionally not different from the working one when using the NM-HDV. ps: I have a PVDM2 sitting on the NM-HDV2, from which a part will be used as dspfarm ('voice-card 1') Kind regards, Juan isdn switch-type primary-ni voice-card 1 dspfarm dsp services dspfarm controller T1 1/1 framing esf linecode b8zs cablelength short 133 pri-group timeslots 1-3,24 service mgcp interface Serial1/1:23 no ip address isdn switch-type primary-ni isdn incoming-voice voice isdn bind-l3 ccm-manager no cdp enable voice-port 1/1:23 dial-peer voice 999 pots application mgcpapp incoming called-number . port 1/1:23 BR1-RTR#sh isdn status Global ISDN Switchtype = primary-ni %Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0.
