> Setting up a 3-Way conference successfully after initiating an attended transfer using DTMF requires both the option atxferswap to be added along with atxferthreeway under general section in features.conf file.
> 3 way conference works when the following configuration is added to the features.conf file.
> [general]
> transferdigittimeout => 3
> featuredigittimeout => 2000
> atxferthreeway = *4
> atxferswap = *5 
> [featuremap]
> atxfer = *1
> 3 way conference  doesn't work when the following configuration is added to the features.conf file.
> [general]
> transferdigittimeout => 3
> featuredigittimeout => 2000
> atxferthreeway = *4
> [featuremap]
> atxfer = *1
> Steps :
> 1. configure 3 sip peers (zoiper, zoiperPhone, blink in my case) in sip channel file sip.conf
> 2. Initiate a call from zoiperPhone (6001) to zoiper(6000). Pick up from zoiper. Initiate a transfer using by dialling *1 from zoiperPhone. Hear transfer tone. Dial the extension 6002 for blink. Hear music on hold on zoiper. Pick up from blink. Convert it to a 3 way conference by dialing *4. 
> Expected:
> Music on hold stops on zoiper
> All three softphones should be connected to the same bridge
> Works when atxferswap is added to features.conf
> Observation:
> When only atxferthreeway is present, after dialing *4, the zoiper phone keeps playing music on hold. The call doesnt cover to a 3 way conference.
