Hi Folks,
I have this silly question, and want to know how proximity behaves in an integrated environment?
I know the endpoints sends token and device identifies etc etc. But we have got 3 WebEx kit plus registered to WebEx cloud and integrated via Crestron. On all of this i am having issues with Proximity. Some times it drops in between, sometimes you just seat in the room for hours and it doesn't detects and sometime it works very good.
So my question is in case of integrated system who is responsible for sending this tokens? I have got sealing speakers in the room connected to codec via DSP. I have also noticed that even though i can connect to proximity there is an error keep on appearing saying "unable to verify ultrasound signal".
I might be wrong but i think those speakers might create interference with those ultrasound pairing?
Regards,
Alok

sorry for the late response on the thread. But Cisco asked to upgrade the IOS version to latest. However they also said the version i had running on the CUBE hasn't been witnessed this issue in past.
But i can confirm that at-least 3 of our customers has ran into this issue on the same IOS version.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCta42890
IOS version before upgrade 3.16.04
IOS version after upgrade 3.16.7b
A temporary fix would be to reload the router to free up the RTP ports.

Hi, You don't actually do NAT'ing on the Expressway-E, what you basically do is you let Exp-E know about the NAT'ed IP-address. The concept of providing NAT'ing IP details on Exp-E is there for a long time before even MRA came into existence. The NIC pointing to public IP you will see an option for configuring NAT IP. Let me tell you even if you won't configure that NAT ip, your MRA will work, but it will create issues with media. Hence its important you provide NAT information on Exp-E. Regards, Alok

Yes, that's correct. Infact for MRA its important to use FQDN's everywhere. However please make sure that you publish the same FQDN outside as well. Regards, Alok

Hi, I guess from the design point of view it looks ok to me. Just to confirm as per your attached network diagram both the sides actually has internet link, correct ? The only problem here i see is that all your AD, DNS servers are actually separated across via MPLS. Do you have a failover for MPLS ? Because consider if MPLS link goes down, that means no more access to DNS and then potentialy no new users can login to MRA. You can build a new DNS for site B, that would be perfect. Recently i ran into same situation however in my case Site B doesn't have any internet Access hence i was forced to install on SITE A UCS, but i had DNS locally at Site A for this. What i would suggest you is that create two separate Jabber profiles and assign the users to local profile in this case. Regards, Alok

Its always best to use a separate Lync gateway for the scenario. However if you are ready to invest in CMS then use the second approach as is mentioned in the document and extend that solution for on premises as well. Regards, Alok

If you would just be asking for scenario 1, the guide below would have been sufficient. https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-9/Cisco-Expressway-Microsoft-Infrastructure-Deployment-Guide-X8-9.pdf However for the other scneario, i think the supported model now is to use CMS. https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-9/CMS-Expressway-Deployment-Guide_X8-9-2.pdf What could be done here to tweak the scenario is instead of using CMS in above document substitue it with LyncVCS (B2B Gateway) and then pass the calls to the LyncGateway for SVC<-->AVC conversion, and use the expressway C & E pair as to have traversal mechanism for your IMP traffic as mentioned in above document. I am not sure if the solution would be supported though. Regards, Alok

In my understanding the Cisco's UC architecture has been changed a lot in recent times. The document for S4B 2015 (assuming its on prem) with 10.5.2 is not been updated even we have 11.5 out for quite a while now, which is clear that Cisco doesn't have any intention to go on that path. All the design documents you see now is to have integration using expressway (For IM&P) and CMS (for AVC<-->SVC) conversion. You can upgrade to x8.9 but then if you go with the current design you would end up buying CMS. If you don't have an intention to buy CMS at this point, go with the broker deployment for Expressway. https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-9/Cisco-Expressway-SIP-Broker-Deployment-Guide-X8-9.pdf Its just that you might have to deploy a new VM for VCS-C/Exp-C and purchase licenses and software accordingly, which you might already have bundled with CUWL in case you have purchased that in recent times. Also i have seen people running broker on the same Exp-C pair which they use for other purposes, but from the support point of view i would recommend to use a separate VM. Look at the below document for more details. https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-9/Cisco-Expressway-SIP-Broker-Deployment-Guide-X8-9.pdf Regards, Alok

Does your SBC has any sort of multiple IP-Addressing ? For e.g. what is 192.168.161.126 or 10.242.32.50 ? Regards, Alok

Can you enable the logs on Expressway-C and then try to add the CUCM. And if you can provide that logs, i can help you to take a look at it. Or as mentioned open TAC with relevant logs and then they can help you. Regards, Alok

Call Manager can't track the CUBE interfaces. So consider this scenario, that you have options ping enable which kind of a periodic keep alive.
So when the CUCM sends the call to CUBE, if the trunk is already down but the timer hasn't been reached to initiate another option's PING, in this case CUBE will try to reach SBC.
But if you keep session transport as TCP (provided the provider also support that), it will detect the trunk down immediately and notify the CUCM, and then CUCM can route the call to second CUBE.
Assuming that both CUBE are sending call to different SBC :)

Alok

Hi Prasad,
I believe you are referring to the link between CUBE 2 to ESBC and not between CUCM and CUBE 2, correct ?
My question is does the CUBE 1 and CUBE 2 sends call towards same ESBC ? Because if the link between CUBE 2 and ESBC is down it means its down for CUBE 1 as well, isn't it ?
Any ways, I think the issue is because of SIP UDP timeout, and CUBE tries for 6 times before CUCM tries to send to CUBE 1.
You can configure the maximum retries in the sip-ua configuration, so that CUBE doesn't tries for 30 seconds before declaring it can't handle the call.
Router(config-sip-ua)# retry { invite number | response number | bye number | cancel number }
Please note that the timer actually starts with value of 0 and then goes on increasing for e.g. 0, 500, 1500, 3500 and so forth till 31500 msec. You can read about SIP UDP timeout in the rfc 3261.
http://www.ietf.org/rfc/rfc3261.txt
I think other way is if you configure the session transport as tcp under dial-peer.
Router(config-dial-peer)# session transport { udp | tcp }

Alok

Hi,
Is the number to be sent with leading "90" ??
To: <sip: 90148455215@10.200.7.157>;tag=sbc0802dba44dda
From the 404 not found by softx, it is complaining about not able to find the number. May be its your translation profile if the prefix number "90" needs to be discarded.
Also the ccsip debug doesn't contains this call, i don;t see this number.
Regards,
Alok
