200 OK—Cisco SIP IP phone C 
to Cisco SIP IP phone B

Cisco SIP IP phone C sends a SIP 200 OK response to 
Cisco SIP IP phone B. The 200 OK response notifies Cisco 
SIP IP phone B that the connection has been made.

If Cisco SIP IP phone C supports the media capability 
advertised in the INVITE message sent by Cisco SIP IP 
phone B, it advertises the intersection of its own and Cisco 
SIP IP phone B’s media capability in the 200 OK response. 
If Cisco SIP IP phone C does not support the media 
capability advertised by Cisco SIP IP phone B, it sends 
back a 400 Bad Request response with a 304 Warning 
header field.

11

ACK—Cisco SIP IP phone B to 
Cisco SIP IP phone C

Cisco SIP IP phone B sends a SIP ACK to Cisco SIP IP 
phone C. The ACK confirms that Cisco SIP IP phone B has 
received the 200 OK response from Cisco SIP IP phone C.

The ACK might contain a message body with the final 
session description to be used by Cisco SIP IP phone C. If 
the message body of the ACK is empty, Cisco SIP IP phone 
C uses the session description in the INVITE request.

A two-way RTP channel is established between SIP IP phone B and SIP IP phone C.

12

INVITE—Cisco SIP IP phone B 
to Cisco SIP IP phone A

Cisco SIP IP phone B sends a mid-call INVITE to Cisco 
SIP IP phone A with the same call ID as the previous 
INVITE and new SDP session parameters (IP address), 
which are used to reestablish the call.

Call_ID=1 

SDP: c=IN IP4 181.23.250.2

To reestablish the call between phone A and phone B, the 
IP address of phone B is inserted into the c= SDP field.

13

200 OK—Cisco SIP IP phone A 
to Cisco SIP IP phone B

Cisco SIP IP phone A sends a SIP 200 OK response to 
Cisco SIP IP phone B.

14

ACK—Cisco SIP IP phone B to 
Cisco SIP IP phone A

Cisco SIP IP phone B sends a SIP ACK to Cisco SIP IP 
phone A. The ACK confirms that Cisco SIP IP phone B has 
received the 200 OK response from Cisco SIP IP phone A.

SIP IP phone B acts as a bridge mixing the RTP channel between User A and User B with the channel 
between User B and User C; establishing a conference bridge between User A and User C.
