Cisco 3845 CME Integration Panasonic KX-TDE600

Hello everybody !!!

I have been facing a call transfer delay at the follow situation.

My scenario are 1 Cisco 3845 CME with 4 E1 links conecting with PSTN and 2 PRI ISDN links connected with Panasonic PBX KX-TDE600.
There are an ICD group at Panasonic PBX, this extension group are receiving calls from PSTN, this calls are comming trough E1 links at CISCO and then trough ISDN link to PANASONIC.

In some situations we need to transfer the call back to Cisco extension, at this case there are a 8 seconds delay

I want to know what are causing this delay ??? And what can I do to solve this problem .???

I'm posting the PANASONIC and the CISCO log for your help.


THANKS A LOT !!!!

Hi

I would start troubleshooting this by doing the following on the CME router:

debug isdn q931

term mon

You should then see SETUP and other messages as they happen. For example, if you make a call to the Panasonic number, you'll see a SETUP message in the TX direction, usualling followed by PROCeeding, alerting, connected and eventually disconnect phases.

When you transfer back to CME, you'll see a SETUP in the RX direction on CME, and a similar sequence of proceeding/alerting/connected etc.

There are lots of places that your delay may have come from, what you need to do is isolate it a little.


With the above debug running, try the transfer - if you see the SETUP message as soon as you try the transfer, post back all the debug info and we'll work out why it delays after that.

If you see the SETUP message 8 seconds after you hit transfer on the Panasonic phone, then the delay is happening on the Panasonic side - it may be an interdigit timeout or something similar, you would need to get your Panasonic engineer to look at that.

I'm Sure that the delay is at CISCO SIDE because Panasonic send the ISDN information very quick.
Maybe is some ISDN misconfiguration between both.

Tarik,

Have you found a solution to this problem?

I am very grateful for the help!

Problem solved very simply: in the settings of QSIG (supplementary services) need to disable the Call Transfer (CT). But at the same time, when transfer call from Panasonic to Cisco (when there is a loop) two channels is involved.

Re: Cisco 3845 CME Integration Panasonic KX-TDE600

It could be possible to have two-B CT supported. But I think it would require a script
