Hey gang,
Two part ISDN question for those willing to take a moment.....
In my lab I have a 5300 (two Ethernet interfaces, DSP card, and T1/PRI
card), a channel bank, and an analog phone. What I’m attempting to do
is connect to a voip peer (2600) over one of the Ethernet interfaces on
the 5300. I can’t seem to get the 5300 to handle the incoming call
properly (switch the call out the Ethernet interface). My dial peers
seem to be correct. When I set serial 0:23 “isdn incoming-voice data”
a connection is established (using a Q.931 debug) but the line is quite
and 10 seconds later disconnects. When I try to set it to “isdn
incoming-voice modem” I get a “Requested circuit/channel not
available” Q.931 error. When I don’t set it at all, I get a “Bearer
capability not implemented”.
Question #1 - What exactly is the “isdn incoming-voice” command used
for? I’ve read some info on the “data”DoV) option, but I’m still
unclear as to which one I should use in my situation. Most examples use
the “modem” option, but I’m not sure why.
Question #2 - does anyone have any suggestions? My part of my config is
below:

fax protocol t38 ls-redundancy 0 hs-redundancy 0

I don't see any udp packets being sent to the 2600. Although a PRI call
using the DoV option is up.
Thanks in advance,
