Preventing call loops
Hello,
I'm using ENUM based routing between the SIP provider and different IP-PBX in a E-SBC environment. A typical local policy looks like:
from *
to <customer DDI range>
source-realm IP-PBX1
policy-attributes
next-hop enum:enterpriseENUM
realm (empty)
Is there a simple way to prevent call loops, e.g. do not allow calls from a SIP interface to be routed back to the same SIP interface?
Best regards,
Alain
