Hi,

I am in the process of testing Call Xfer Blind & Attended , Call Forward
feature for our product. I would like to know what are the field values in
each packets exchanged between the 2 UAs that I should look for to prove
the same works for my product.

Eg : SIP Phone A makes call to SIP Phone B. RTP Packets get Xchanged
between the 2 UAs. SIP Phone B puts the same call on Hold.

In this eg: I need to check the "c" field in the Re-INVITE packet sent from
SIP Phone B to SIP Phone A with the value "C=IN IP4 0.0.0.0 to prove that
the call is actually on hold apart from the fact that RTP packets do not
get exchanged between the 2 UAs while the call is on hold.

Likewise, what do I need to check for Call Transfer (Blind & Attended) and
Call Forward??? Any good pointers to test the same features would be highly
appreciated.

Thanks in advance...

Regards,
Milan Sengupta.
