Hi All, hope you can assist.
I've seen a lot of posts around this particular issue.
A lot of my agents are describing an issue where an inbound call connects to an agent, the agent connects, agent hears silence and then the call drops. Another example would be, the inbound call momentarily rings on the agents phone, but disconnects before the agents has a chance to connect the call.
A lot of posts have mentioned codec mismatch or region issues. I have noted that the CCX ports and CTI route points are in the same device pool & region. The agent phones are in another device pool and region. However, there is no relationship between the regions. It is configured to "use system default".
Any ideas of theories would be most appreciated.
Thanks
Jamie

Hi All,
Was hoping you could assist. The company I recently joined uses contact centre, consisting of 150 agents. Most agents use an 8865 that connects directly to an access switch and registers to CUCM via a WAN link, so all fairly standard.
However, all the desktops use an IGEL solution which is VDI. This connects to Microsoft RDS for all their applications, including Finesse.
Practically every agent reports issues with inbound call connectivity. Either the call connects and there is silence, or Finesse freezes or they see the call appear on their phones, Finesse goes into a reserved state, but the calls disconnects before they are able to answer the call. It's happening very frequently.
CUCM and UCCX are located on the same UCS server, in the same DC. The VDI sessions are located in Azure's cloud is my understanding.
I'm wondering if the VDI solution is causing signalling and CTI issues. My next step is to configure a local desktop/laptop and remove the virtual desktop solution from the equation.
Any thoughts or ideas would be most appreciated.
Thanks
Jamie

Hi Ayodeji,
Thank you for your response. Agreed, I did make an assupmtion regarding the format of the number and will contact the ITSP to clarify.
Please let me know what you mean by defining a range for my DDI on both inbound/outbound call leg. My ITSP will be presenting me with a single number that I want to route to CUCM.
Great advice and thanks again.
Regards,
Jamie

Dear All,
I need to upgrade the firmware for our 8851 phones to the latest release of 11.0(1) (from version 10-3-1-20)
Do I need to upgrade the device pack to the latest version for CUCM 10.5.2 in order to use V11.0(1) for the 8851 phones? Or can I simply download the individual firmware release (as seen below) for the 8851 phone and upload that instead of the device pack?
8851 firmware V11.0(1) - cmterm-88xx-sip.11-0-1-11.k3.cop.sgn
Current versions:
CUCM Version: 10.5.2.10000-5
Active Device Pack Installed: cmterm-devicepack10.5.2.12014-1.cop
8851 Active Firmware: 10-3-1-20
Our entire cluster is only running two end points: 8851 phones and 8831 conference phones. We don’t have any new phones on our phone system and I want to avoid uploading a new device pack as it requires a full reboot of the cluster whereas uploading the individual firmware only requires a restart of the TFTP service.
Thank you very much in advance, hope you can help.
Regards
Jamie

Hi All, I was hoping some of you could assist me with an Etherchannel issue that I encountered when connecting 2 * 1 GB lacp bundled ports from a Cisco 6513 to an F5 load balancing appliance. Details of Equipment: Cisco 6513 Version: sup-bootflash:s72033-ipservicesk9_wan-vz.122-33.SXH6.bin Includes: 48-port 10/100/1000 RJ45 EtherModule WS-X6148A-GE-TX BIGIP: Model: 6800 Version: 10.2.4 Cisco port channel configuration: interface Port-channel17 switchport switchport access vlan 246 switchport mode access Interface port configuration: channel-protocol lacp channel-group 17 mode active BIGIP “trunks” as they are called have been configured as follows: Interfaces: untagged Speed: auto speed/ Duplex: auto Protocol: lacp LACP Mode: Active LACP Timout: Long Link Selection Policy: Auto Frame Distribution Hash: Source/Destination IP address Once I activate the port channel on the Cisco and BIGIP, the following etherchannel summary appears: 17 Po17(SU) LACP Gi1/48(P) 17 Po17A(SN) LACP Gi13/3(w) The ports on the Cisco end attempt to bundle and for a moment, both have a “P” flag, until one of the ports dropout under Po17A as seen above. I have played with the various modes (on, active & passive) but to no avail. I even changed the port channel to a trunk (on both Cisco and BIGIP), but the ports refuse to bundle. Lastly, I have hardcoded the speed and duplex settings on both ends but again, the port channel does not bundle. Even more bizarre, we have a datacentre design where all our network devices are configured as hardware HA pairs. Having applied the exact same configuration to our standby 6513 and BIGIP, the port channel interfaces bundle together as soon as the portchannel is activated. Any advice would be most appreciated. Jamie

Hello All, I was hoping someone could assist with an issue that our Exchange team are having, specifically with replication traffic traversing our DC to DR site. The infrastructure consists of a Layer 3 data centre and a disaster recovery site, so essentially its a live/backup environment. Both the DC and DR site are connected with a LES using routed interfaces. The Exchange cluster at the DC is associated with the following subnets: MAPI - 10.1.30.X Replication: 10.1.230.X DR site has the following subnets associated with the exhange cluster : MAPI - 192.168.4.X Replication - 192.168.230.X When an attempt is made to create a database/mailbox on an exchange server at the DC and copy it using the replication subnet source: 10.1.230.X to destination subnet: 192.168.230.X, the copy process fails. Replication traffic in general going from DC to DR or vice-versa is subject to constant problems and seems unreliable. Our exchange team have to manually copy mailboxes from one cluster to the other using Windows explorer which works fine. The Exchange cluster at both sites reside within a VMWare ESX enclosure and connect to Cisco 6500 switches. Would the Cisco switches require a static arp entry for their respective Exchange clusters, which should be configured on each switch? If this was missing could this be the root cause of the replication problems we're experiencing? Or does this depend on whether the exchange cluster is using NLB Unicast or Multicast mode? Any assistance would be most appreciated. Regards, Jamie

Morning all, I recently rebuilt the configuration of our Cat6500 multilayer device for use as a user stack. The device is funtioning as it should be, but I am unable to set SSH using the 'crypto key generate rsa' command. The crytop command isn't avaiable at all, which suggests a firmware issue. I have configured a hostname and Ip domain-name and the image is the only one available.

Hello All, I was wondering if anyone knows how to use the call forward feature on a shared line for a 7970 phone. The sofkey is available but is 'greyed' out for some reason. I had a look at the softkey template and there is no option that refers to a shared line. Surely there is a way of setting up a call forward feature from the phone rather than having to go through the cucm user admin page? Thanks Jamie

Afternoon All, We have recently changed our codec from G711 to G729 for a handful of our remote branches. We achieved this by changing the region on CUCM and updating our branch voice gateway by applying the preferred codec onto all the relevant dial peers. However, we have had some examples of the following scenario: Calls to an IP phone through a gateway fail when a transfer to another phone is attempted. The user picking up the transferred call recevies a busy tone and then the call diconnects. The voice gateway in question shows the incoming call codec as G729 and no errors appear when we apply a debug to the router. Voice Gateway: 2801 (IOS - 12.4T) CUCM Version: 7.1(3) 7970 phones Has anyone come across this? Would be handy to know before I attempt to setup alerts on RTMT. Thanks Jamie

Hi All, If I were to place an internal call from our main site to one of our branches across our managed WAN, would to total bandwidth consumed be 80kb or 160kb assuming each of the phones in question were using G711 as their Codec? Thank you. Regards Jamie
