Hi
I have a 3745 router and I have just replaced my single VWIC E1 card with a dual VWIC E1 card. However I only have 30 lines working. Can someone please tell me how to get the second E1 PRI ISDN line to work? Many thanks in advance.

No worries. You have:
dial-peer voice 104 pots
destination-pattern 0 <-- It should be really 0T, but if it works...
direct-inward-dial <-- Not needed for outgoing DP
port 3/0:15
You also need:
dial-peer voice 105 pots
destination-pattern 0T
port 3/1:15
This configuration uses multiple dual-peer and is not the more sophisticated trunk-group one. Its ok for your basic needs.
Note, under voice-port 3/0:15 you have some settings that you may want to replicate for 3/1:15 as well.
Note again, most of your dial-peer are redundant and could be eliminated/optimized.
Hope this helps, please rate post if it does!

Do you use the PRI for voice? If so, do you have enough DSP resources to suppoer 60 channels ?
What is the exact error that you encounter ?

Hi
The 2 PRI's are both used for voice. The VWIC is populated with all 5 DSP boards, so suffucient DSP's are available.
The problem I have is that the second PRI line is never used. Using "Show Voice DSP" or "Show Voice Call" I can see that only the first thirty lines are used for calls.
On the 31 concurrent call the softphone that I am using just says "Bad Number" or "Address Unknown": and there is no activity on the second PRI line.
I suspect it is an IOS setting which is not correct. I can swap the PRI lines in the router and always the first 30 work proving it is not a dodgy PRI line. I have two routers configured equally and the problem is on both of them ruling out a hardware fault.
Many thanks for your time.

Hi,
are these incoming our outgoing calls? "Show controllers E1" and "show isdn status" please ?
Finally, relevant router config please ?

Hello,
For incoming, assuming both circuits are under the same hunt-group, telco has probably set things so that calls go fill the first circuit and then use the second. If you want a different behavior, ask them.
For outgoing, you do not have an outgoing dial-peer for the second interface. You can do that either creating a dial-peer, or putting both interfaces in a trunk-group, and referencing the latter in dial-peer.
Hope this helps,please rate post if it does!

Hi
You say -
For outgoing, you do not have an outgoing dial-peer for the second interface.
How do you identify a dial peer with interfaces? Sorry, I know I must be missing something which is obvious to you but I can't see it. Many thanks in advance.

Hi
I think this is it - I have been concentrating on the Dial-peer voip one only.
dial-peer voice 104 pots
destination-pattern 0
direct-inward-dial
port 3/0:15
I guess I need another one for port 3/1:15??

Many many thanks for your kind assistance.
Roger that on the replication of settings and now that I have a better, but still small, understanding of dial-peers, I will delete the gratuitous ones. Best regards - Steve
