[SIPForum-discussion] without registering a IP phone , Can we make a call?

[Thomas Trung]

Hi Michael,

The answer is no if you are using IP PHOne.

Yes, if you are using VOIP Gateway. Some of kind VoIP gateway can be support
sip peer-to-peer like sip trunking so you can make the call from the phone
connected to the first voip gateway to the another phone connected to the
second voip gateway.

Hi All,

if one phone is registered to registrar server, 2nd phone is not registered
but 1st phone knows the IP address of 2nd IP Phone

Please tell me if i am not clear.
