Hello Francesco, Sorry to be adding a question to this thread but I presume it is related. Regarding "The only way to get rid of the certificate warning on iPads, it will be to present a public cert signed by a trusted authority.", I have recently worked on a new ISE 2.3 deployment and migrated services across from the old 2.1 deployment, and have initially utilized a public cert signed by a trusted authority for EAP. It worked fine without any warnings on browsers however we had to accept / trust the certificate on Microsoft and Apple client devices, or with a wireless gpo for windows workstations to trust the top CA in the certificate hierarchy. Just wondering if there is any specific requirement on the public cert to work on EAP without manually requiring to trust the certificate? Thanks. Regards, Lay

Hi Scott, I know it is an old discussion but just wanted to share how I retrieve a VM from CUC. My CUC version is 8.6.2, not sure if 8.5.1 has the same feature to forward a VM. Here is my workaround: Enable "Receive a copy of voicemail feature" on the extension where we will be forwarding the voicemail to. You can do that by setting "Message Action" for vociemail to "Accept and Relay the Message" and by entering the email address in Relay Address. Prerequisite: SMTP host must have been configured in CUC. Access to the voicemail box which we want to retrieve from and Enter PIN when prompted. Choose "Forward" option and the system will ask you to spell the first name of the destined extension. Use keypad on the Cisco VoIP phone handset to enter the name (E.g. 72688 for Scott). A copy of voicemail message will then be directed to destined extension. Since it has been configured to send a copy of voicemail to destined user's e-mail, the voice-mail message will come in as an email. It turns out to be quite useful for us as the message shows the original time stamp and caller ID, if any. Hope this helps. Regards, Lay

Thanks Manish again for this. I did get few MediaReosurceListExhausted events from RTMT alerts but was not paying much attention to them. Location bandwidth settings have been checked and increased a bit for sites which were repeatedly getting these events. I will monitor to see if that reduces these alerts. Could you please advise how I can verify it is hitting the maximum limit? I have also raised this with Cisco TAC and some cores were found on the CUC subscriber server. We seemed to have run into a bug according to Cisco TAC as in here https://tools.cisco.com/bugsearch/bug/CSCug61581/?reffering_site=dumpcr and both CUC servers have been upgraded to 8_6_2_24901_1. It has fixed cores and we are now monitoring the voicemail service for few days to see if it will reoccur. Regards,

Thanks very much to both, Manish and Brian. Sorry I could not get back to this as the work has been a bit overwhelming with some issues. One of the recurring issue was 'voicemail being unresponsive'. I have started a discussion about this at https://supportforums.cisco.com/discussion/12224456/voicemail-does-not-respond-cuc-862-and-cucm-862-environment but unfortunately it didn't get any attention. I am not sure if both issues are related. In my understanding, it could be related to number of voicemail ports but not sure how to confirm it. In this no ringback tone issue, IPVMS has been restarted but I am still not getting ringback tone via CallHandler. Regards,

layhlaing · ‎06-25-2014

Thanks again, Manish. Sorry, I have just edited the last post to correct the IP. I have replicated a similar Call Handler at the site where I can capture packets on VG. I have same issue regardless of ISDN or SIP trunk. 10.6.130.15 is VG and 10.6.130.11 is CUCM. This VG also has the same configuration except from numbering plan as the one that was posted at the beginning. Phones use DP for MRGL and they are the same in any case anyway. Regards,

Hi Manish, Thanks again for your time on this. and sorry for my ignorance but would the ringback tone be initiated as MOH in this? The packet capture on CUCM server 10.6.130.11 for this particular port 4000 with "utils network capture eth0 file packets count 100000 size all port 4000" gave me followings which is consistent to the previous CUCM trace. Source - Destination - Source Port - Destination Port 10.6.130.15 - 10.6.130.11 - 18696 - terabase (4000) Wireshark span monitor session on VG does not have such packet however I wonder why as there should not be any filtering. I can hear MoH if the call is answered and put on hold. Enabling MTP required on the SIP trunk between CUCM and VG has given me call dropping issue in the past so I am cautious with that. Regards,

Thanks again for your assistance. I have simulated a test call via a test call handler that just has been created. Calling number: 0467784687 Called number: x7477 (Via Test Call Handler) Time: 14:10 WAST Please find attached CUCM trace. Early offer support in the SIP profile was disabled as it was giving some issues. Or should I create a specific SIP profile with early offer just for that site?

layhlaing · ‎06-21-2014

Sorry for the delay. Please find attached traces for the last test call. The time of the call was Jun 20 21:14 WAST. Thanks again.

layhlaing · ‎06-20-2014

Thanks very much again. I have enabled early offer in the SIP profile and the trunk has also been restarted. Please find attached logs. It is a direct call to an extension as last time and the ringback tone went away after about 5 times for five sessions. Regards,

layhlaing · ‎06-20-2014

Thanks for that. I have done a test call as advised - a direct call to an extension which redirect to other extension by CFB/CFNA. Please find attached output of debug ccsip message. Even with this, I just become aware that the ringback seems to go silent (maybe time out?) after about 5 rings in all five sessions as traced, as in RTMT screenshot. Regards,

layhlaing · ‎06-20-2014

Hi, More checks have been done to confirm but I could not verify this. Have also done NMap scan but port 4000 was not in open list (both TCP and UDP). Have also check on VG using an access-list but there was no hit at all. Music-on-hold is there though when the test call was put on hold. Would you be able to explain why I am seeing '401 Unauthorized' in CUCM trace for the test call please? I should also mention that both of our CUCM and CUC servers are on dual-stack IPv4 and IPv6 but VG has only IPv4. Thanks again. Regards,

layhlaing · ‎06-19-2014

Thanks again for that. 10.101.130.10 is the CUCM subscriber where end-points on that site register. There is no filtering between CUCM and VG but when I try to capture it using an access-list, I have no hits as yet. I will check again in an another way to confirm. Thanks. Regards,

layhlaing · ‎06-18-2014

Thanks very much for that. Please find attached output for debug ccsip message from the VG. Regards,

Hi everyone, I am having no ringback tone issue on incoming calls via CUC call handler in the following environment. CUCM: 8.6.2.22900-9 CUC: 8.6.2ES44.22900-44 Integration between CUCM and CUC: SIP End-points: Cisco 9951 SIP, Cisco 7960 SCCP, Cisco 7942 SCCP VG: Cisco 2921 with E1/PRI with PVDM3-128 Outbound Trunk: ISDN 30 channels Trunk between VG and CUCM: SIP Ringback tone is there if calls were made directly to DIDs. The call handler call flow is as this: -> 08 9333 7401 -> CFA - voicemail -> CUC CallHandler -> No greetings during BusinessHour, always transfer -> x7404 -> CFNA/CFB -> x7411 -> CFNA/CFB -> x7412 -> CFNA/CFB -> x7413 -> CFNA/CFB -> Mobile Attached are VG config and debug output of 'debug voice ccapi inout', 'debug isdn q931' and screenshots from RTMT for the following test call: Calling number: 0467784687 Called number: 0893337401 There was a ring, just once, "180 Ringing" message is there, as you can see in the screenshot 'Analyze Call Diagram*' but it has gone silent after that. Both SIP trunks between CUCM and CUC have MRG (with active Annunciator) associated and they are 'MTP required' with 'MTP Preferred Originating Codec' of g729/g729a. The SIP trunk between CUCM and site's VG also has MRG (with active Annunciator) associated and it is not 'MTP required'. As you can see in the VG config, our codec preference 1 is g711ulaw. Can someone please advise on how I should approach on this issue to be resolved? Thanks in advance. Regards,

Hi, We started experiencing issues in which voicemail just went into silence without responding anything recently when we completed migration of sites from Unified Communications 6.0 to 8.6. I did not see any related message in RTMT or console on any of CUC or CUCM at the time and had to reset the SIP trunk to resolve the issue. In some cases, it was required to restart CUC servers to resolve the issue. Followings are our 8.6 environment details: CUCM: 8.6.2.22900-9 (One Publisher and two Subscribers) VMware Installation: 2 vCPU Intel(R) Xeon(R) CPU X5570 @ 2.93GHz, disk 1: 80Gbytes, 4GB RAM CUC: 8.6.2ES44.22900-44 (One Publisher and one Subscriber) VMware Installation: 2 vCPU Intel(R) Xeon(R) CPU X5570 @ 2.93GHz, disk 1: 200Gbytes, 6GB RAM Integration between CUC and CUCM: SIP integration There are 399 voice-mail ports in our CUC cluster and ports 1 - 200 are on the subscriber and they are assigned to answer calls, and the next ports 201 - 300 are on the publisher and they are assigned for Message Notification/MWI dial-out. The last ports 301 - 399 are on the subscribers and they are assigned for Message Notification/MWI dial-out. Can someone please share your knowledge if you have experienced similar to this in your environment? Thanks in advance. Regards, Lay
