Octel 250 intergation with Cisco CallManager Express

[acsee]

Does anyone have any advice on integrating the Octel 250 with the CallManager Express? We have a need to do so and for the most part it works with the minor exception of transferring calls.

The Octel has 8 FXO ports, one of which is dedicated to MWI only as stated by Cisco. What happens is when a caller calls in to either the Auto attendant or 0s out from a mailbox, you hear the DTMF tones and the call drops. We've tried changing the hook flash time at various increments from 500ms to 2000 (max) ms. When the hook is changed to 1200ms, you no longer hear the DTMF tones but the call still does not transfer- same with the higher flash values. We've tested hook flash and transfer on the CME by directly connecting to an FXS port with an analogue telephone and it works fine.

Any suggestions, etc would be greatly appreciated as this has been an issue for months now.

What type of PBX is the Octel set for in menu 1-1 and what line type are you using for the ports?

Hi Ken,

Many thanks for the reply:

The PBX type is set to 2 (other) and the line types are set to type 1.

 

[KenMeans]

So you are using inband from the Cisco ?

Also do you ever see the transfer in the online CDR? It may be that the Octel does not like the dial tone from the Cisco system and will not transfer the call.

Try changing the line type to a 3 or 4 and see what it does.

Thanks for the reply again,

Here is what I received from the Octel admin:

Yes we are using inband and you do see the call in CDR.

With line the line type changes:

Type 2 & 3 – no change

Type 4 & 5 – got a response immediately that the open trees ext. 9530 was not valid

Types 17 – 19 not valid options

Types 33 – 35 not valid options

Thanks!

Haven't been able to resolve- any ideas?

I'm having good success integrating a 250 to CallManager using an analog gateway (VG248) and treating the CallManager as if it were a Centrex. Call data comes across as SMDI data across a serial port, the voice path goes across analog lines, and everything works fine.

I'd recommend using SMDI rather than inband.

Hi CJ,

That is what we would have been done in a CCM/Octel integration but this is a CME/Octel integration. Unfortunately we can't do serial integration with the router.

 

[KenMeans]

So just to make sure you are saying that it all works fine but the transfers right?

Hi Ken,

Yes all else is working including MWI- just not the 0 out transfer, AA transfer, or Dial by name transfer.

Analog transfer was tested on each port of router and was found to be working on the CME side- but we are perplexed as to where the problem is.

 

[KenMeans]

I think it is in the CME side. Do you have an analog station from somewhere else that you can hook up and test with ? I have seen some odd things with the CM on analog ports and it was always in the Cisco side.

Can you post a printout of a online cdr of a transfer as well as menu 6 1 and 4 1 1

Also the dial tone that you get on the analog sta is it normal or some other type of dial tone ?

Thanks Ken- Yes it is a normal dialtone. We noted this procedure for a direct (not conferenced/supervised) transfer:

flash dial number flash- we had tried that to no avail as well.

I will obtain the CDR and menu outputs and paste here.

Thanks again!

[KenMeans]

one thing to try is on menu 1-2 change the Supervised Return to Operator: N to a yes and see if it will transfer the call.

What kind of gateway are you using for the analog ports? I have seen where the Cisco will reverse the polarity on the analog line on any state change and that would make the call drop during a transfer from the Octel.
