When your calling router try to bring up the second channel, in case
there is one dial string only, so the calling router would call the same
number again.
1. the remote ISDN switch detect the incoming call address the same
number / channel while the channel is already connected, so it would
response you with BUSY.
If you calling router configure another dialing string, then your
calling router would give it a try, so in that case, say the Telco ISDN
switch doesn't support / configure hunt-group function, then you have to
configure two dial strings / numbers.
2. the remote ISDN switch detect the same info as 1, while it was
configured with hunt-group so it would automatically shift to the second
number / channel, in that case, you only need to configure one number /
string.
Correct me if I was wrong.

Subject: ISDN: One or Two Dial Strings
Can anyone tell me when to list the dial strings for both BRI channels
and
when to list just one (dial string of map statements)? I have seen it
done
both ways. I apologize if this issue has been discussed previously.
Couldn't find an answer in the archives.
Thanks,
Karl Brusen
