Hi,
I have a little problem with some SPA514G and my UC320W.
My configuration is simple, we have a UC320W with a sip trunk to my service provider and we have 6 SPA514G.
Everything works fine for internal call and external call trough my SIP provider but 2 SPA514G hangup external outgoing call after 32 seconds.
When I analyse a trace in my voice vlan during an outgoing call from my SPA514G phone, the UC320W send a 200 OK SDP SIP Status to the phone but my SPA514G don't respond with a ACK message and after 32 seconds, the UC320W send a Bye message because he don't receive a ACK message.
For the 4 others SPA514G, all phones send a ACK message to the UC320W.
the UC320W and the 6 SPA514G was installed in the same time. The configuration of all the phones are similar. My UC320W have the last software version 2.3.x.
I have factory reset this 2 SPA514G and that not solve my problem.
If you have some idea, I remain open at all purpose.
Thanks for your help and sorry for my english.
Best regards
Alexandre
