I have set up ILS in a lab environment.
i cannot seem to exchange URIs.
can you give me any other troubleshooting advice?
Thanks a lot for your question, thanks for clarifying what you have already done
Just to clarify this:-
- To enable URI Replication in a cluster, check the Exchange Directory URIs with Remote Clusters check box that appears in Intercluster Directory URI Configuration. When this check box is checked, each cluster sends the following to the other clusters in the ILS network.
Your config looks fine, however it would be nice if you could clarify the following
1. It seems that you have done the basic requirement, however could you please double-check that you have "Exchange Directory URI Catalogs with Remote Clusters" checked on all nodes especially on the Hub Cluster under Call Routing Intercluster Directory URI Configuration, hit export & open the .csv file to check if there are any Directory URI's populated in it.
2. Please ensure that you have Use "Fully Qualified Domain Name in SIP Requests" in the Sip Profile under Device > Device Settings > Sip Profile
3. On the Sip Trunk, please ensure that the "Calling and Connected Party Info Format" is set to Deliver URI and DN in connected party if available.
4. How are we making test calls & what are you using, you referenced CSF Devices is jabber used, if yes then what version is used
- Could you clarify what happens when you try to make a directory URI from one cluster to another. Do you receive a busy/reorder tone.
- Are we using any Partitions & CSS's while testing this.
Feel free to reach out if there are any further questions & id be glad to help.
I hope this helps.
Thanks for your question.
thanks for your response.
is checked on both clusters. (this is a very basic set up - when i say 2 clusters - it is effectively 2 separate publisher nodes)
on both clusters, this opens a .csv popultaed with the single 1 URI i have created on each cluster (once i'd associated each CSF to the end user).
This is set
This is set
There are no CSS' or partitions, the directory URI Alias partition is null.
I am not making any test calls, what i am expecting to see is a single imported URI from each cluster on the corresponding hub or spoke cluster
under Call Routing ->Inter Cluster Directory URI->imported Directory URIs
Am i correct in assuming that this should be the case?
Thanks a lot for your promp response, Only 3rd party directory URIs that were manually imported into the cluster should show up under Imported Directory URIs.
Local directory URIs will not be reflected in there.Local directory URIs are saved in the local Unified CM database. All other directory URIs are saved in CSV files that are maintained by ILS. When directory URI replication is enabled, ILS exchanges all types of directory URIs to the other clusters in the ILS network.
Following are some Directory URI catalog types
Within an individual cluster, directory URIs can be categorized as follows:
- Local directory URIs—Directory URIs that are configured on the local system and which are saved in the local Unified CM database.
- Remote directory URIs—Directory URIs that were configured in another cluster and then replicated to this cluster.
Imported Directory URI catalogs—Third party directory URIs that were manually imported into this cluster.
- Remote Imported Directory URI catalogs—Third party directory URIs that were manually imported into another cluster in the ILS network and then replicated to this cluster with ILS.
Local directory URIs are saved in the local Unified CM database. All other directory URIs are saved in CSV files that are maintained by ILS. When directory URI replication is enabled, ILS exchanges all types of directory URIs to the other clusters in the ILS network.
Do let me know if this answers your question.
thank you for clarifying this point for me.
i think i am nearly there.
if i login to the hub cluster and run the
utils ils lookup "URI from remote cluster"
a route string appears that matches my SIP route pattern to the spoke cluster.
if i run the same command from the Spoke cluster (referencing a hub URI), nothing appears. I will review the configuration again,
FYI all works fine.
I am using CUCM 9.0 and was referencing a URI without remembering that 9.0 host portion is case sensitive,
I think i will be good to go ahead and test now,
many thanks again
I had attended the Webex on UC few months back in which term Alpha URI was mentioned and can be used for dialing to IP phones users using their names.This is what I know.
I just wanted to know the pre-requisties in terms of IP phones models, CUCM exact version , any extra hardware and benefits to customer of implementing URI if we approach customer having CUCM 9 setup.
Thanks a lot for your question, URI Dialing was introduced in CUCM Version 9.0,Starting with Cisco Unified CM 9.0, provisioning and dialing of alphanumeric directory uniform resource identifiers (URIs) is supported by Unified CM.
To know what phones are supported, i would request you to navigate to Cisco Unified Reportings Page on your CUCM 9.x, then select Unified CM Phone Feature List & select URI Dialing in the requested feature that you wish to check, in this instance URI Dialing.
- Following is the list of supported phones for your reference:-

This information is extraced from my lab cucm version 9.1.
- I would recommend that you use cucm 126.96.36.19900-5 which is available on cisco.com.
- Any supported hardware is fine, but we have a lot of customers migrating to UCS these days.
- A URI could be considered just as an alternative to a DN, For endpoints registered to Unified CM, this adds dialing a directory URI as a new dialing habit.
As per RFC 3261 (section 19.1.4, URI Comparison) comparison of the userinfo of SIP URIs has to be case-sensitive. According to this standardized behaviors, Amit@cisco.com and firstname.lastname@example.org are not to be considered equivalent. When routing directory URIs, Unified CM respects this standard and looks for a case-sensitive full match of the user portion and a case-insensitive match of the host portion. To avoid confusion, Cisco highly recommends provisioning only directory URIs with all lowercase userinfo so that all directory URIs can reliably be dialed by entering all lowercase information.
Unified CM 9.1 and later releases can be configured to always use case-insensitive comparison of the user info portion of directory URIs. This can be achieved by configuring the enterprise parameter URI Lookup Policy accordingly. This setting applies to matching locally configured directory URIs and also to matching directory URIs for which an ILS lookup is done. The default setting of this enterprise parameter defines standard compliant case-sensitive matching of the user info portion of directory URIs.
Cisco is also promoting a new Drive-to-9 intiative where you could get attractive discounts if you plan to upgrade your existing CUCM to 9.1, please reach out to your local accounts team for further clarifications on this.
Do let me know if i have managed to answer your question, if not do let me know your doubts & i'd be glad to clarify them out for you.
Thanks for prompt reply.One more query:
I was going through the query asked by Mr. Stuart .In case , if we have a single cluster , then, we do not require ILS service.Please advice.
Secondly, how do we dial from IP phone using URI .Do we get any separate directory like Corporate Directory available on IP phone?
Thanks a lot for your question, if you just have a single node then call-routing is done just like a basic DN to DN call,Calls to URIs on the local cluster are routed using partitions and search spaces & you do not need ILS in this instance.
When calls are to be made between different clusters,in this instance,URIs are replicated between clusters using the Inter-cluster Lookup Service (ILS). When a call is made a lookup is done in ILS to figure out what SIP trunk to route the call out of.
To Dial from a phone hit the new call key > hit the more key you then have the options to type alphabets as well as numbers, i will try to attach a screen-shot from my lab phone at the earliest.
Do let me know if i was able to answer your question & feel free to ask if there are any further clarifications needed & i'd be glad to help out.
