1: If I call a user directly using a land line (through PSTN), SNR works fine.
2: If I call the same user directly from a Cell Phone (through PSTN) SNR does NOT work.
Customer is using UC540 with 8.0 code. Has been happening since installed.
SIP is configured.
Using 509/508 sets. With latest code, Single line, NO hunt group or anything else configured on line, .
I am just wondering if anyone has seen this behavior.
Cannot image it is a Cisco issue. Would appreciate suggestions on what to debug or
what I can ask a Service provider to look for.
