[asterisk-users] Clicking Noise on Pure Voip Calls

[carl Lougher]

Setup:
Asterisk server in NY.
Cisco 7960 IP Phones in NY and London.
Dedicated T1 from NY to Ldn.

T1:
Latency - 100ms
Qos applied
No errors

Default codec on Ldn IP Phones = g711alaw
Default codec on NY IP Phones = g711ulaw
Both codecs allowed on each phone.

Issue:
Calls on IP Phones from NY to London hear clicking
noise on NY end.

Anyone experienced something similar or can offer some
assistance?

Thanks,
Taf..
