setup: CME with a couple phones served by a 2 line BRI on 12.4(15)T7. Problem: outbound calls are fine on either spid. Inbound calls work on first spid but second spid rings twice and then stops. Calling party hears continuous ringing and call appears rejected.
I previously posted this problem under the topic "CME with BRI cannot answer second inbound voice call" but there is a new and intriguing development: The example above is based on a switch type config of basic-NI, but if I change the configuration to basic-5ess the first channel now has the problem and the second works fine.
I'd think this is a carrier problem but I don't believe they can provision each channel/SPID of a BRI with different signaling.
I've opened another ticket with the carrier to ask the question but is it possible? Can the carrier provision one channel of a BRI with NI/DMS100 and the other channel with 5ESS?
Any thoughts on this? I'm willing to try anything.
Thanks in advance!
