Guys I need help.
This UCM 6202 has been working fine with a successful ring group of 3 devices (Gxp 6525, 6105 and 2200 extension 1000,2000 and 3000). The ucm uses 2 analog lines. Suddenly started to ring In just 1 phone. I’ve upgrade the dice to the latest version so far 188.8.131.52, upgrade phones as well, erase and make the extensions and inbound patterns (_s, _xxxxxxxxxx, _xxxxxxxxxxx) an the ring groups as well. If I send the calls to an extension individually instead of the ring group would not ring either.
