I have a customer with a MICS 5.0 with PRI. It has 2 station mods. 6 port exp. 1 clocking card.
On certain phones, when the handset is lifted for making a call - no internal dialtone is returned for approx 5-10 secs. When answering the phone - same thing. No connectivity to the party for 5-10 secs. Once connection is made - call quality is fine.
This occurred on one phone - so I replaced the phone and it has been working. Then it occurred on another phone. Replaced and OK. Now I have 3 more phones. They are not on the same module.
Any thoughts? I'm going to site tomorrow and can check the event codes.
