Common/Reasonable Assumption on DID/Channel over-subscription


Hello All, just throwing this out there. What are people generally using these days
when designing their services, esp. those that require a user to call a DID
to access their system, similar to calling card services. There was a time
when this used to be 50 to 1 for DIDs, and about 10 to 1 for number of
channels bought in SMB with IP-PBX. I believe this would have changed today and assuming a service is pretty

ITSP failover for PRI


Hi, I still have the same problem trying to configure ITSP failover in
extensions.conf for a connected PRI. Any comments thoughts or direction
