Hi,
I'm doing tests with some sipsorcery and voxalot accounts, registered with siemens gigasets. Here are the results of my tests (all the calls are between SIP URIs):
1) Calls between sipsorcery accounts: OK
2) Calls between voxalot accounts: OK
3) Calls from voxalot to sipsorcery: OK
4) Calls from sipsorcery to voxalot: mute call in both directions
Can someone help me? Is this a kown problem treated in some thread?
Alberto
P.S. may it be related to the port forwarding of the modem router? I changed something in the rules for ports 5060-5062, and the result is that now the test 4) is OK and the 3) fails. Or maybe there is something not reproducible (random) behind...
