SLRG selection criteria CUCM

[AnantSharma2616]

Call flow: Inbound call

pstn >>> Cube1 >>> Trunk >>> translation pattern >>> RP >>> Cube1

Here, the RP is part of a route group which has SLRG configured. What i know is that SLRG uses calling party's Device pool to find the gateway/end device. How SLRG will be selected in this scenario where neither the TP nor the RP has device pool settings on them?

Thanks

For SLRG, RP detail are mentioned on device pool.

on device pool page you can see Local route group option.

Which device's Device Pool should i look for ?

[Nithin Eluvathingal]

Calling party's Device pool will have Local Route Group Configured.

Let me rephrase it: Which is the calling party here as the call is coming from PSTN to Sip trunk and then matches with TP and RP?

Is it the Incoming SIP trunk?

In this case it will be the Device Pool of the trunk or gateway that receives the inbound PSTN call.

Yes it’s the Device pool of the incoming sip trunk
