A collaboration engineer is troubleshooting an MOH problem on a Cisco IOS SIP gateway. While searching through a debug ccsip message output, which three parameters in the SIP messages can be used to determine if the call was placed on hold? (Choose three)





E. c=IN IP4


    Answer: B,C,E Explanation:

    Ensurepass 2018 PDF and VCE

    When a call is on hold you get something like this: v=0

    o=CiscoSystemsCCM-SIP 919861 2 IN IP4

    s=SIP Call

    c=IN IP4

    t=0 0

    m=audio 30120 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=ptime:20


    a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15

    The connection parameter shows, When the call is taking off hold you, the connection parameter should indicate the ip address where media is sent to. So it will have a real value. ( This is usual sent in the ACK.) cucm still sends a DO in the re-INVITE and the far end sends a 200 Ok with SDP. CUCM then sends ACK with SDP

    This is how the whole call hold/transfer/call resume works

    1. CUCM sends invite (re-invite) with an inactive SDP (a=inactive) to indicate a break in media path

    2. CUCM sends a Delayed offer to insert MOH or to resume Media stream

      NB: CUCM expects a sendrecv offer with SDP to the DO. (NB:if cucm gets an inactive offer SDP in the 200 OK instead of providing a send-recv offer SDP, the media path remains in an inactive state and causes calls to dropcall will drop),CUCM sends an ACK with sendonly to the 200 OK

    3. CUCM establishes newcall leg with the intended transfered destination..Once this call is connected

    4. CUCM receives a new Transfer instruction from the transferring phone to connect the held party

    5. Next CUCM sends a re-invite with an inactive SDP to indicate a break in media path to MOH (in attempt to complete transfer)

    6. Next CUCM sends an inactive SDP to indicate a break in media path between transfering party amp; transfered party to remove Xferring party from call

    7. Next CUCM sends a DO re-invite to connect the transfered party. The far end then sends 200 OK with the required SDP to connect the call

A cisco collaboration engineer is troubleshooting a gateway and gatekeeper problem and sees this output from a debug command. Which two configuration can cause this problem? (Choose two)

  1. The same zone prefix is configured in two different gatekeepers

  2. The same H323-ID is configured in two different gateways

  3. The same gw-type-prefix is configured in two different zone subnets IDs

  4. The same zone subnet ID is configured in two different gatekeepers

  5. The same E164-ID is configured in two different gateways

Answer: B,E

Explanation: This output from the debug h225 asn1 command shows a registration reject reason of duplicateAlias.


value RasMessage ::= registrationReject :


requestSeqNum 24

protocolIdentifier { 0 0 8 2250 0 3 } rejectReason duplicateAlias:



gatekeeperIdentifier {quot;gkquot;}


This is usually the result of the gateway registering a duplicate of an E164-ID or H323-ID: Another gateway has already been registered to the gatekeeper. If it is a duplicated E164- ID, change the destination pattern configured under a POTS dial-peer associated with an FXS port. If it is a duplicated H323-ID, change the gateway#39;s H.323 ID under the H.323 VoIP interface.
