Cisco 2811 vs Nortel PBX 11C via E1PRI (DMS100)

[Gerardo Fajardo Perez]

Hi all,

Had this interoperability between Cisco 2811 E1 PRI with DMS100, because Nortel Opc 11C´s  E1 Card does not support Net 5 or QSIG, so it is used DMS100 instead. All the Channels go UP on both PBX and Router, but when try to dial a number to the PBX through a FXS it received an error tone, and when used csim start from the Router it is received :

csim err csimDisconnected recvd DISC cid(43)
csim: loop = 1, failed = 1
csim: call attempted = 1, setup failed = 1, tone failed = 0

Any suggestion ???

Thanks in advance.

About DMS 100 not sure, but I'm sure that Nortel 11C E1 PRI card supports qsig without any problem and it works with Cisco gateway as well.

Can you attach running config of 2811 router and "debug voip ccapi inout" as well to have more clarification.

Hi Suresh,

Attach the information requsted, 

Thanks in advance.

Can you collect and attach "debug isdn q931" in the same call scenario?

[Gerardo Fajardo Perez]

Here it is.

Thanks a lot.

Looks like the Nortel side doesn't like the progress message.  Try adding "voice call send-alert" to your dial-peers so that you send an actual Alerting message instead of a progress message with a progress indicator.

Hi Brian, 

Send the capture after typing "voice call send alert".

Thanks in advance.

Get the debug isdn q931 output.  That doesn't give us any info.

[Gerardo Fajardo Perez]

Here it comes...

Thanks

[Brian Meade]

Looking better. Now also add: Progress_ind alert strip 8

[Gerardo Fajardo Perez]

Hi Brian,

Could you tell where add "Progress_ind alert strip 8" ?

If it is in the Dial-Peer, attach you the options I have.

Thanks a lot. 

[Brian Meade]

Should be on the dial-peer but I think it's a hidden command.  Did you try running it as is?

[Gerardo Fajardo Perez]

You´re right !, its hidden. Even though,  call is not succesfull.I put the command in both dial-peers, and sounds the same.

Attach the debug q931 about that.

Thanks 

[Brian Meade]

That got rid of the progress indicator in the alerting but it's still complaining about that alerting message for some reason.  Might require some debugging on the Nortel side on why it doesn't like the sent information elements.

Hi Brian,

There was changed the Nortel´s E1 PRI Card NTAK79 for the NTDB50, and now is working with IFC> ISGF, so problem was solved. This is the one I have already worked with.

Thanks a lot for your support.
