[cisco-voip] dial-peer related question

Wed Sep 10 06:28:08 EDT 2008

Hello my friend,

Please attach the e1 configuration on your AS. I want to see how many
timeslots are configured. Second you may run debug isdn q931 and get the
cause code of failure. May be you have incoming calls also and you need
to change the B channel selection sequence on the ISDN interfaces.

Yes they both look fine and there are calls up on both links. Do you
know if all of the active calls on E1's in the information you provide
are for outbound calls that have matched the 0301T pattern? If they are
then that suggests your dial-peer configuration is correct and calls are
being spread between the two dial peers 4003 and 4006.

Try running - debug isdn q931 when you make the 31St call and see if
that provides any insight on why the call is not going though.

Have both the E1's been provision by the telco as full 30 channels or
could they be fractional E1's?

I think yes. You can see following information.

Hi guys

I have 5350 gateway and gateway connected to internet via gigenthernet,
connected to ISDN by 2 E1 ports via PRI. 

Dial peer looks like this : 

dial-peer voice 4002 voip
  voice-class codec 1
 session target ipv4:61.250.94.66
 incoming called-number 0301T
 dtmf-relay rtp-nte h245-signal h245-alphanumeric
 fax-relay ecm disable
 fax rate 9600
 fax protocol t38 ls-redundancy 2 hs-redundancy 2 fallback none
!
dial-peer voice 4003 pots
 destination-pattern 0301T
 progress_ind alert enable 8
 direct-inward-dial
 port 2/0:D
!
dial-peer voice 4006 pots
 destination-pattern 0301T
 progress_ind alert enable 8
 direct-inward-dial
 port 2/3:D
!

The call coming from dial-peer 4002 and outgoing to 4003, 4006.

30 calls came from 4002 to 4003 and 4006 it can handle when 31th call
came it couldn't. 
I think 2E1 card can handle 60 calls. but it didn't.  I think problem in
configuration.

How to solve it?

Thanks for any help

Sincerely,
Tseveen.
