Here is a strange experience needing a few explanation.
I install today an UC540 with soft pack 8.0.4 and CCA 2.2.5. All is good as always.
I encouter a big problem for this customer while testing call forwards.
When i take a call on a SPA500 phone, i can transfer it without any kind of problem on both inside and oustide phones (internal extensions, GSM,...). This works good both for internall calls or incoming ones from outside.
My routes are good on my SA, SIP trunk weel registering, with UDP session and IP.
My problem is in this case :
Extension 207 forwarded on GSM A
If calling extension 207 with another inside phone, call forwarded perfectly.
If i try to call Extension 207 from GSM B (so from outside), i got the ring tone, GSM A ring well, but when picking up the call : no voice...
On my SA i have tried everything. Allowing everything out from UC to WWW, allowing everything from my ISP IP to my WAN UC IP, disableing firewall rules, allowing everything inside and oustide for 5 minutes...
Still the same, got my phone ringing, earing the tone, but not the voice.
