I have a few Cisco SPA112 with Cordless phones attached to them. Everything works fine but I am having trouble finding the exact procedure to transfer calls to another extension. Call transfers from IP phones works ok.

What is the exact key sequence to press on analogue sets? The SPA112 are being auto provisioned. I am attaching a photo of the cordless phone keys in this forum post.

I will appreciate if anyone could tell me if this is possible, and which keys to press.

Hi Stefan,

the SPA112 is able to do a blind/attended transfer by detecting the "hook flash" (known in the UK as "recall"). According to the picture it should be the "R" button.

First you must configure the SPA112 to detect a hook flash. Log in the web administration of the adapter and enable the "Blind Attn-Xfer Enable" option on the "Line 1" screen.

Then, after pressing the "R" button while on a call, you should hear a new dialtone and be able to do the transfer.

My Analogue Siemens phone's hook flash signal was not properly detected, because the signal was too short. I had to decrease the "Hook Flash Timer Min" on the "Regional" screen to "0.05" to make it work. You might need to do it as well.

Worked like a charm, with the 0.05s setting.

Perfect! Thank you!
