ISDN BRI in Spain CME 2801 Issue

I am trying to install a 2801 CME router with VIC2-2BRI-NT/TE onto telefonica supplied BRI Circuits. I cannot get layer 2 up. their circuits are setup as Point to point is their anyway to get the CME to work with point to point? I have already set the Interfaces with point to point setup but this still does not bring layer 2 up. below is a debug ISDN Q921 and errors.

Re: ISDN BRI in Spain CME 2801 Issue

Hi,

I have recently configured a BRI in Madrid wth the same provider.

The most important is probably the TEI config. See below our config :

Interface BRI0/0/0

no ip address

isdn switch-type basic-net3

isdn point-to-point-setup

isdn incoming-voice voice

isdn static-tei 0

If it doesn't work, please post you running config.

Re: ISDN BRI in Spain CME 2801 Issue

Good news for layer 2 ;-)

Have you tried incoming calls?

It could be a problem with line coding or number/type presentation, channel selection...

Please send a show run, it will be easier to debug...

Thanks,

Fred

Re: ISDN BRI in Spain CME 2801 Issue

Hi,

The call is getting rejected by the carrier, and the cause code they send back to your router is:

Cause i = 0x82E404 - Invalid information element contents

So one of the information elements that the router is sending in the outgoing SETUP message is not correct. My guess is that the Bearer Capability is not correct. From your debugs, the bearer capability in the ougoing setup is 0x8090A2, which decodes to Voice/Speech call (u-law). Because the switch-type is Basic-net3, I think the call should be A-law instead (0x8090A3).

Try setting the compand-type to alaw under the voice port.

voice-port 0/2/1

compand-type a-law

ISDN Bearer Capability Values are defined here:

I agree with mowuor...

That's what we configured in Madrid...

Re: ISDN BRI in Spain CME 2801 Issue

Hi Michael,

perfect answer we are now able to make successful outgoing calls.

I only noe have a problem with the incoming now.

the telco is sending me the following 933436xxx and this is translated to an internal extension 6XXX however the call is unsuccessful.

Re: ISDN BRI in Spain CME 2801 Issue

Hi Ian,

If dial-peer voice 1 is intended to be used for inbound calls, then change the incoming called-number statement from 'incoming called-number 6161' to 'incoming called-number .'

Let us know how this works.

Regards,

Michael.

New Member

Re: ISDN BRI in Spain CME 2801 Issue

We had origionally done that and set it to 6161 to see if it would work so in both instances we cannot get incoming calls.

show voice translation-rule is correct

and test voice translation-rule matches also.
