dear colleagues,
I have configured Cisco 2811 RAS with E1 for dial in access for several remote locations which have analog modems.
When I test with test server (with modem) I can access all resources in my LAN, but when several remote locations start to connect i get following error:
Jul 13 08:43:58: %ISDN-6-CHAN_UNAVAILABLE: Interface Se1/0:15 Requested Channel 11 is not available

google told me that this is dsp resource problem but I don't understand what to do. please be so kind and help me.

1.) sh-stuff.txt (sh version, sh modem ver, sh diag, sh controllers e1 1/0, sh isdn service)
2.) running-config
You have created pri-group with first 10 timeslots (10 channels), but the other end requests 11th-13th timeslots (11th-13th channels). So first make sure how many and which timeslots (channels) are avialable for connection. Second make sure that both ends are configured the same way.
controller E1 1/0
pri-group timeslots 1-10,16
I think it should be (if You get 30 channels from other end):
controller E1 1/0
pri-group timeslots 1-31
Could you be so kind and tell me following:
I have configured
line 0/322 0/357
no flush-at-activation
login local
modem InOut
modem autoconfigure discovery
transport input all
transport output all
autoselect during-login
autoselect ppp
Should I put then 0/322 0/353 (322+31)?
kind regards,
Valentin

"line 322 357"
2811 ISR
In PVDM0 slot, first modem is at line 322
Your PVDM has 36 modems so last modem will be at 322 + 36 (-1) = 357

we solved our problem with VPDN and Radius. it appeared that remote locations don't have static IP address but DHCP. so, we put remote locations and wanted IP addresses into radius and now everything works like a charm
thanx to all for suggestions!
