[SIPForum-discussion] Can A call to B party without proxy?

[arvind shukla]

Hi All,
I have one confusion plz help me in that. In sip protocol when A call first time to B party it don't have B's address so, in this case proxy should be there in between A and B. But once A party will know the B's party address then can it be possible for the second time when A call to B, A directly can reach to B without proxy or for the second time also it needs a proxy in between to call B from A.
Please give the solution for this.
 
 
Thanks in advance,
Arvind
