A cisco VOIP engineer is configuring QoS for the company switches. configuration must be based on two requirements: - The switch port must trust all traffic coming from the IP Phone. - The switch port must remap all traffic coming from the computer to COS 0 Which two sets of commands satisfy these requirements?

  3. F. FastEthernet 0/1 mls qos trust device cisco-phone Answer: A, B Question: 3 Refer to the exhibit. The SIP service Provider does not support re-invites unless media changes. Which two commands are needed on the CUBE to standby the SIP service provider requirements? (choose two) A. media flow-through B. midcall signaling preserve-codec C. media flow-around D. midcall-signaling passthru media-change E. media anti-trombone F. midcall-signaling block Answer: D, F Question: 4 Refer to the exhibit.

  4. An engineer is analysing a SIP call between CUCM on the left and CUBE on the right. Based on the information displayed, which behaviour can be determined from the exhibit? A. The mid-call re-invite negotiated for call hold/resume supplementary service B. The call has interworking issues where user is not experiencing audio C. The midcall-signaling block is configured on Cisco Unified border element so re-invites are not consumed D. The call is terminated because 200 Ok messages are not arriving to Cisco Unified Communications Manager Answer: A Explanation/Reference: A Re-INVITE, it comes after a session has been established. This means that it will apply to an existing INVITE after a final response has been received and an ACK has been sent. You send an UPDATE message prior to session establishment, but that’s an article for another day. A re-INVITE will have the same Call-ID and From tag as the INVITE it is modifying. It can change every other header as well as the message body, but those two things tell the SIP stack that this is not a new INVITE. The most common use for re-INVITE is call hold. The party putting the call on hold sends a re-INVITE with SDP indicating that media will no longer be sent. That same party will take the call off hold by sending another re-INVITE with SDP indicating that media transmission will resume. To demonstrate this, I placed a call to my desk telephone, answered it, started up the Avaya traceSM utility, put the call on hold, stopped traceSM, and then took a few screen shots of the resultant call flow. https://andrewjprokop.wordpress.com/2015/02/10/understanding-sip-re-invite/
