[SIPForum-discussion] SIP billing confusion

[Luckow , Roy]

For me only step 05 can be correct!

Lets say UA 1 cannot handle the SDP Media from UA2( in Step 04). The connection cannot be setup.

Betreff: [SIPForum-discussion] SIP billing confusion

please consider this sip call flow:



A                                        B
01        INVITE
     ----------------------------------->
02       100 TRYING
    <------------------------------------
03       180 Ringing
    <------------------------------------
04       200OK With SDP
   <----------------------------------------
05       ACK
   ------------------------------------------>
06             BYE
   <------------------------------------------
07           200 OK
   ------------------------------------------->


Query:
1. Is there any rfc recommendation when to start bill and stop it, some says its start after 4 and stop at 06 some says its start after 5 and stop at 7?

2. is it ok if someone start bill after 05 and stop after 06?
