Contact: <sip:14487000004 at 192.3.3.31:5060;+g.3gpp.cs-voice=+g.3gpp.cs-voice>;+g.3gpp.iari-ref="urn%3Aurn-7%3A3gpp-service.ims.iari.rcse.im";+g.3gpp.iari-ref="urn%3Aurn-7%3A3gpp-application.ims.iari.rcse.AMIT.serviceLA";+g.3gpp.iari-ref="urn%3Aurn-7%3A3gpp-application.ims.iari.rcse.VF.serviceE";+g.3gpp.iari-ref="urn%3Aurn-7%3A3gpp-service.ims.iari.rcse.amit1234"

<sip:14487000004 at 192.3.3.31:5060;+g.3gpp.cs-voice=+g.3gpp.cs-voice>;

is this correct or it should be
