CUCM Sip trunk 404 loop

[albrto1982]

I have a cucm version 8.6.2 and a SIP trunk with a SBC. 172.23.129.8 is the CUCM and 172.23.129.35 is the SBC

I want to know how can i avoid 404 loop.

Hi.

Did you check these two service parameters value on CUCM?

Stop   Routing on Unallocated Number Flag

Stop   Routing on User Busy Flag

Ensure that they are on "True" Value

You did the trick!!!

I enabled "Stop   Routing on Unallocated Number Flag"

Thank you so much.
