[cisco-voip] easiest and quickest way to disable a PRI PSTN (MGCP) port?

[Daniel Pagan]

Same… but I think the main difference is that, with the service parameter change, CUCM won’t send the MGCP CRCX to the gateway for any specified B-channels in a “maintenance” state – they’ll simply be skipped. With the IOS statement, and without running it in a lab, I would think the MGCP CRCX will be sent to the gateway since CUCM has no knowledge of the isdn statement (and since all channels were reported in service during the AUEP/200 exchange at registration) and the call would be rejected at the MGCP level (i.e. 5XX).

I thought that didn’t work with MGCP PRIs. Did that change? In the past I used the CUCM service parameter  (Change B-Channel Maintenance Status) to busy them out.

This is great. I like the idea of busy'ing out the channels.

And I just tested it, it's additive, not destructive, so I can simply add busy channel statements and it groups them.

Thanks everyone.

Assuming that you don't care about dropping any active calls:

controller t1 X/X/X
  shutdown

Otherwise, you could busy out the channels that are not in use (sh isdn
service to see status).

interface SerialX/X/X:23
  isdn busy b_channel 0-24
