Just installed an UC320W with SPA8800.
UC320W version 2.2.2 (1)
SPA8800 version 6.1.10 (GW003)
Everything works fine on UC320W itself. include that analogue phone which connected to FXS port on it.
But analogue phones connected to SPA8800 FXS ports can't call ANYWHERE (Internal extensions or external numbers). Phone just keeps playing a long breaking tone after we dial the numbers.
Inbound are ok. Other IP phones or external caller can call those Analogue phones.
Not always happen.
First time when I install. it happened on phones which connected to FXS 1 and 4. then did a factory reset. happened on all phonoes. Factory reset again.
only happened on FXS 2.
I am sure someone else has the same issue. but can't find any solutions online.
