I have an issue where only calls coming from the PSTN have a slow to start an stop ring time.
When I call from the PSTN I hear ring back for two rings before my analog (or SIP) phones start to ring, then if I hang up the call before it is answered the analog (or SIP) phone continues to ring for 2 more rings?
When I call out this is not the case or with internal calls.
I am connected to the PSTN via a TDM400P.
Any thoughts?
Cheers!
Dave
