[SIPForum-discussion] Transactions in basic call hold scenario

[senthil k]

U mean to say when there is a proxy the number of transactions is doubled
???

so if there are 2 proxies in between then it will be 21 ??

can any one clarify me that the proxy being in between the users makes the
transaction by two ( ion both the sides ?? )


Thanks in advance
Enthi
