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:
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
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?
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.
