Transfer calls from analog phone on FXS port

mcreilly
Level 1
Level 1

I have an analog device (specifically a BT "Diverse 6450" DECT cordless handset) attached to an FXS port in a 2851 which is configured for SCCP and registering with a CM 6.1.2 cluster. I can make and receive calls on this phone no problem, but I can't transfer them.

The phone has an R (recall) button that does a hookflash. I don't know what I've missed but that doesn't cause the phone to provide a dialtone. If I ring the phone from a desk phone (eg a 7945) I can hear the click-click of the hookflash when I press R, but Call Manager doesn't respond to it.

The port is configured like this:

voice-port 0/3/1

cptone GB

timeouts ringing infinity

timing hookflash-in 250 45

description Reception Mobile

station-id name Reception Mobile

station-id number 4124004

caller-id alerting pre-ring

and a dial peer like this:

dial-peer voice 1031 pots

service stcapp

port 0/3/1

I've tried all sorts of values for the "timing hookflash-in" (including removing that line to default it), but no joy.

I'm sure I'm missing something very very simple here but I've been looking for solutions most of the morning and can't get it working yet. Replacing the phone with a 7921G wireless phone is my proposed solution but I'd have to order one and that would take a few days, I'd like to get the analog device working for now.

Anybody able to point me in the right direction?

Thanks!

You have a typical european hookflash duration of 100ms, have you tried timing hookflash-in 80 ?

I've also found that on most handsets you can change the hookflash timing to medium and leave router with defaults.

Can you take a "debug vpm signal" when pressing the R key? Make sure you have configure service timestam debug msec.

Certainly!

Here's the output (with comments):

Fantastic, thanks for that. Problem solved!

"timing hookflash-in 80" resulted in calls being disconnected when pressing R but I tried "timing hookflash-in 120 60" and now it works fine. I was trying increments of 100 at a time before.

Hi MCreilly,

Looks like I have exactly the same issue. but I have used the same values as you did but no succeess

the only difference is that I am using a BT diverse 6250 rather than your 6450. (still should be the same !!)

we are using CUCM 8.5

the port is on VG224 as,

voice-port 2/0

cptone GB

timeouts ringing infinity

timing hookflash-in 120 60

caller-id enable

caller-id alerting pre-ring

the dial peers

dial-peer voice 201 pots

service stcapp

fax rate disable

port 2/0

I am hearing the same Click click when presssing the R key on the phone.

can you please advice if there was something else you did as well.

thanks

Abbas
