Panasonic ns1000 and Asterisk

Hi all…
I have this scenario…
the calls arrives to a Panasonic ns1000…then via IVR they land to Asterisk…then on some circumstances they are redirected to a SIP Phones on Panasonic…

Is there a way to release Asterisk role and to set free Asterisk ?

Asterisk register to Panasonic as a sip endpoint…

Panasonic register to Asterisk as a sip endpoint…

Sorry if i’m lacking usefull informations…

Asterisk can release SIP calls providing there is only one leg.

If there are two legs, the best you can do is use directmedia=yes, which I believe is now default, to make the media go direct.
