I am attempting to add single number reach capabilities to DNs in a hunt group used for emergency support. SNR works as expected when dialing the associated DN directly, both the desk phone and the remote destination ring. However, when calling the hunt pilot number that has the DN in its line group only the desk phone rings. The call is not extended to the remote destination.
Configuration is as follows:
Any suggestions before I open a TAC case?
Mobile Connect, or Single Number Reach as it’s better known as, is not designed to work with hunt pilots from what I know. It does from my experience work if you use broadcast as the distribution algorithm on the hunt pilot.
Start troubleshooting at the GW(s) do you see the call being made?, if yes, what do you send and what does the telco reply?
If not, you go back to CUCM and look at the traces to see what is going on.
We are using a similar setup and it is working with no issues.
Hunt Pilot - Hunt List w/ 1 line group - Line group (broadcast w/ 20 second RNA Reversion) with 6 DNs
2 of the DNs are on the same cluster and those DNs have SNR on them to cell phones (no issues with the routing to cell phones). The other 4 are SNR direct (i.e.no phone associated just a CTI port configured). The timers we have set are Wait 1 second and Delay 4 seconds. Stop ringing is 19 seconds.
Have you tried adjusting your timers?
I've adjusted the timers but no change. It doesn't appear to be a timing issue as there's no call setup to our PSTN gateway (answer to Jaime's question). I only looked at the q.931 traffic on the PSTN side, I'll have to debug the voip side and look at UCM traces. I think I'll try the CTI port + SNR option as well.
Jabber for mobile over MRA is an option to avoid SNR altogether. We definitely ran into timing issues with hunt groups and the Jabber mobile client during pandemic lockdown. Not sure if that was related to push notification services, client version, etc., but it wasn't 100% reliable at that time.
Yes, but the problem was something that I should have caught to begin with. The line I was testing with was shared on Jabber CSF and Jabber mobile clients but only the CSF client was logged into the hunt group. The test line gets used for a lot of scenarios and wasn't set back to a clean start. The hunt group now successfully extends calls via SNR using CTI, Jabber, and 88XX phone.
