[cisco-voip] configuring ISDN PRI into 30 seperate channels

[Kelemen Zoltan]

Hi,

you (and your customer) probably don't need to actually separate the 30 
channels. You can have DIDs and you can have outgoing CallerID so each 
user will have his/her own number. Also, since there are only 30 users, 
it's quite improbable, that at any one time, the ISDN would be full, so 
any user can get a free line at any time. These together are practically 
no different, than each user having his/her own separate channel.

AFAIK, you can't manage separate channels in MGCP either. (or if there's 
any chance, you probably have better chances to do it in h323)

What is the exact requirement of the client? What does he need to be 
solved? Those are the questions that need to be answered, not trying to 
replicate 1-on-1 the legacy PBX's (presumed) functionality.

regards,
  zoltan
