Hi there, I have CUCM-BE running on a BE6000M. The CUBE is also running on this device and the device is in the DMZ. So set-up is: CUBE <---DMZ--->F5 firewall <----> ITSP Note: CUBE is on a private IP address and only one interface is been used The issue here is that the f5 firewall only dose L3 NAT and the SIP SDP packets are not inspected. Is there a way to do this on the CUBE? If there is no way to do this on the CUBE what are the alternatives? Thanks alexis p.s as a side not is there a better way to deploy this solution? ...

Hi there, On the RTMT there is a pre-configure alert called HardwareFailure. The description of this alert states: "This alert occurs when the HardwareFailure event is generated. This indicates that hardware failure event (disk drive failures, power supply failures,...) has occurred." Is there a way to check using one of the AXL interface on CUCM on that hardware status (same as the pre-configure alarm) that the CUCM VM is sitting on top to check that there is no alerts? I had a look around the RISService interface but only found CPU Memory etc.. thanks alexis ... View more

  Hi there,   I have the following call flow set-up: CUCM 10.5 <==> SIP <==> CUBE 15.3 <==> SIP <==> Telco   Incoming calls work fine. Outgoing calls to mobile only are failing. When the call is made the mobile phone will ring but one's its answered the call is drop. To me this would suggest that this a codec issue   Below are the debugs but the only thing I see is " SIP/2.0 500 Internal Server Error"   From: "Alexis"<sip:0131306XXXX@ippbx2.XXXXX.co.uk>;tag=E9322CC-734 To: <sip:07759134XXXX@ippbx2.XXXX.co.uk>;tag=94040 Call-ID: E1C23D57-F49011E4-8595C68F-103E8103@135.X.X.X CSeq: 102 INVITE Via: SIP/2.0/UDP 135.X.X.X:5060;branch=z9hG4bK12C8431009 Content-Type: application/sdp Contact: <sip:077591XXXX@135.X.X.X:5060> User-Agent:  Nortel SESM 14.0.16.3 Supported: replaces,tdialog P-Asserted-Identity: <sip:anonymous@135.X.X.X> Allow: INVITE,BYE,CANCEL,ACK,REGISTER,SUBSCRIBE,NOTIFY,UPDATE,MESSAGE,INFO,REFER,OPTIONS,PUBLISH,PRACK x-nt-location: -1 Require: timer Timestamp: 1431072782 Session-Expires: 1800;refresher=uac Content-Length: 260 v=0 o=sbc-uk-wv-g001a 16215776 16215777 IN IP4 135.X.X.X s=sip call e=unknown@invalid.net c=IN IP4 135.X.X.X t=0 0 a=sendrecv m=audio 40428 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:20 008852: May  8 08:13:09.754: //1519569/0A7980800001/SIP/Msg/ccsipDisplayMsg: Sent: SIP/2.0 500 Internal Server Error Via: SIP/2.0/TCP 10.X.X.X:5060;branch=z9hG4bK517066a6d6e026f From: "Alexis Katsavras" <sip:44131306XXXX@10.X.X.X>;tag=15171831~5ef6baea-c4ed-5f9e-769a-02a480f7b0f7-35096096 To: <sip:90775913XXX@10.X.X.X>;tag=E932D04-15FA Call-ID: a798080-54c1700e-29ad51-a0c640a@10.X.X.X CSeq: 101 INVITE Content-Length: 0 008853: May  8 08:13:09.754: //1519570/0A7980800000/SIP/Msg/ccsipDisplayMsg: Sent: ACK sip:0775913XXXX@135.X.X.X:5060 SIP/2.0 Via: SIP/2.0/UDP 135.X.X.X:5060;branch=z9hG4bK12C8461859 From: "Alexis Katsavras" <sip:44131306XXXX@ippbx2.XXXX.co.uk>;tag=E9322CC-734 To: <sip:0775913XXXX@ippbx2.XXXX.co.uk>;tag=94040 Date: Fri, 08 May 2015 08:13:02 GMT Call-ID: E1C23D57-F49011E4-8595C68F-103E8103@135.X.X.X Max-Forwards: 70 CSeq: 102 ACK Allow-Events: telephone-event Content-Length: 0 008854: May  8 08:13:09.754: //-1/xxxxxxxxxxxx/SIP/Msg/ccsipDisplayMsg: Received: ACK sip:90775913XXX@10.X.X.X:5060 SIP/2.0 Via: SIP/2.0/TCP 10.X.X.X:5060;branch=z9hG4bK517066a6d6e026f From: "Alexis Katsavras" <sip:44131306XXXX@10.X.X.X>;tag=15171831~5ef6baea-c4ed-5f9e-769a-02a480f7b0f7-35096096 To: <sip:90775913XXX@10.X.X.X>;tag=E932D04-15FA Date: Fri, 08 May 2015 08:13:02 GMT Call-ID: a798080-54c1700e-29ad51-a0c640a@10.X.X.X User-Agent: Cisco-CUCM10.5 Max-Forwards: 70 CSeq: 101 ACK Allow-Events: presence Content-Length: 0 008855: May  8 08:13:09.758: //1519570/0A7980800000/SIP/Msg/ccsipDisplayMsg: Sent: BYE sip:0775913XXXX@135.X.X.X:5060 SIP/2.0 Via: SIP/2.0/UDP 135.X.X.X:5060;branch=z9hG4bK12C847BC8 From: "Alexis Katsavras" <sip:44131306XXXX@ippbx2.XXXXX.co.uk>;tag=E9322CC-734 To: <sip:0775913XXXX@ippbx2.XXXXX.co.uk>;tag=94040 Date: Fri, 08 May 2015 08:13:02 GMT Call-ID: E1C23D57-F49011E4-8595C68F-103E8103@135.X.X.X User-Agent: Cisco-SIPGateway/IOS-15.3.3.M Max-Forwards: 70 Timestamp: 1431072789 CSeq: 103 BYE Reason: Q.850;cause=16 P-RTP-Stat: PS=216,OS=34560,PR=164,OR=26240,PL=0,JI=0,LA=0,DU=0 Content-Length: 0   Any help would be great Thanks alexis ...

Hi there, I have a question relating to the CSS that is used by the SIP trunk when a call is been transfer From:UC To:CUCM IP Phone I have a System Call Handler that’s when dialled if the user press 0 will transfer the call to a second System Call Handler which is configure to transfer the call to an IP Phone using the Transfer Rules All that works OK without any issues My question is this. The SIP trunk used by UC into CUCM Calling Search Space dose NOT have access to the Partition that the call is been transfer to. So this should NOT work but it dose. The only way I see this working is if the SIP trunk is using the "Rerouting Calling Search Space". Is this the CSS the trunk uses as i was under the impression it was just the standard CSS? I have also check the traces of the call on CUCM and cannot see it using the "Rerouting Calling Search Space" Thanks Alexis http://www.netpacket.co.uk http://www.blog.netpacket.co.uk    ...

Hi there I am looking for some help in replacing a Subscriber in our CUCM 9.1 cluster. A server had a disk fault and after replacing the faulty parts I am now looking to rebuild the subscriber I am following this document: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/9_1_1/replace/CUCM_BK_R1B1A464_00_replace-server-cluster-cucm-91.pdf So have the following questions as older version of CUCM we just build the Sub and waited for the db synch. 1. After the initial install of the CUCM software do the services start up in the Sub automatically? (phones switch register with it) or do they come up after you go through the DRS for the subscriber? ("Replace Subscriber or dedicated TFTP server" Step 6 ) 2. After the services come up on the new Subscriber do the phones automatically register with the subscriber or do we need to reset the "CM Group" which contains the Subscriber 3. Which parameters (hostname, IP add, NTP etc ..) must match exactly with the original for the DRS import to work? Thanks Alexis http://www.netpacket.co.uk/ http://www.blog.netpacket.co.uk/         ...
