Implementing SAF on CUCM Clusters

[Ahmed habib]

Hello,

I want to implement SAF on cucm clusters but I don't under the scenario and how will configuration be done and how did I check after configuration

Shall I configure every cucm cluster PUB as SAF Forwarder?

I revised SRND and SAF configuration document but it isn't clear to me https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/saf/configuration/xe-3s/saf-xe-3s-book/saf-configuring.html

Please, I want a clear document or video for this feature scenario and configuration

Note: I made the configuration in the guide but when I check I found

#show eigrp service-family ipv4 subscriptions
EIGRP-SFv4 VR(saf) Subscriptions for AS(1)/ID(192.168.178.125)
No active subscriptionsW

#show eigrp service-family ipv4 clients
EIGRP-SFv4 VR(saf) Clients for AS(1)/ID(192.168.178.125)
No Clients attached to this Forwarder

SAF has been superceeded by Inter-Cluster Lookup Service (ILS). Do not use SAF in production unless you have a corner-case that somehow precludes the use of ILS.

Thanks both for your interest but I don't want URI dialing

I just want to use SAF and CCD and I applied the configuration but when I try show commands 

show eigrp service-family ipv4 clients
EIGRP-SFv4 VR(saf) Clients for AS(1)/ID(192.168.178.125)
No Clients attached to this Forwarder

GW#show eigrp service-family ipv4 subscriptions
EIGRP-SFv4 VR(saf) Subscriptions for AS(1)/ID(192.168.178.125)
No active subscriptions

GW#show eigrp service-family external-client Habib
Detail data for client -- Habib
Username: admin Version: 1.2
Client Context: AS (1): AFI: IPv4 Topology: Base
Router Name: saf
Config Using as Client Basename

I made the configuration on two cucm test clusters but no one is active

Can anyone help me ?

router eigrp saf
!
service-family ipv4 autonomous-system 1
!
topology base
external-client Habib
external-client Habib1
exit-sf-topology
exit-service-family

service-family external-client listen ipv4 5050

I got finally the two clients registered

Is there a method to show the patterns learned on cucm or must show on RTMT ?

and Is should add manually every pattern I need to advertise ?

and Calls are done from one side only , if dialed from the other it gets fast busy tone although the learned pattern shown and all is reachable

Hi, for various reasons I need to implement saf. You said you had issues then get it working- what issues and how did you get them resolved

Thanks

[Roger Kallberg]

Why do you need SAF? It’s much better and easier to use ILS with GDPR. What is it that you want to achieve?

[Iptuser031516]

I've got Ils working now but reading different posts I have some questions

People have stated the directory numbers are not advertised and you need to make use of alternative enterprise number, alternative e164 which work however if I do not select them and advertise only the real directory numbers only then ils works as well. I was told, read that Directory numbers are not advertised only the alternative enterprise ones are but it works - why?

• Thanks 

[Roger Kallberg]

Sorry, but I don't quite understand what you wrote. Would you please re-phrase it and provide a little more specific details? If you can provide pictures to show what it is that you refer to in CM that would be great.

With GDPR/ILS you should generally not advertise individual numbers, what is done on the DN level. Instead you should advertise patterns from the Call Routing > Global Dial Plan Replication > Advertised Pattern menu as that provides a much leaner/easier way to maintain what each leaf cluster advertises.

[Roger Kallberg]

Besides this your question about ILS/GDPR is off topic to the OPs question. With that it is recommended that you create a new post to continue the ILS/GDPR line of question so that we can help you out.
