I have Linksys SPA400 and can't get Caller ID on incomming calls. Waiting for firmware that will fix this over 2 years.
I use this adapter on 2 installs: one with SPA9000 and one with Asterisk. Same problem with both.
I am from Bulgaria. Telecom operator Vivacom ( formerly BTC ).
With SPA3102 Caller ID is working fine. Settings are ETSI FSK - bell 202 and FXO Port Impedance 600
Tried all suggestions in other posts with no success.
Also I find a document from my provider that describes specifications for end-user devices:
Specification ETSI ETS 300 6593 FSK
500 ms ≤ T5 ≤ 2000 ms
T6 ≥ 200 ms
T 9 = 0 ms to 150 ms
T 10 = 0 ms to 150 ms
T 11 = 40 ms to 55 ms
T 12 = 55 ms to 200 ms
T 13 = 40 ms то 120 ms
T 14 = 160 ms ± 5 ms
Can you give me some advise how to get CLIP from my lines?
