i'm trying to configure yate and with a snom 715. When enabling SRTP encryption the yate pbx complains about the snom sending invalid SRTP packets:
SRTP HMAC recv: e4dfae70 calc: 0a1071eb seq: 66331
an idea what could the cause be of this?
Incoming SRTP from the SIP trunk works fine, so i would assume yate and the snom doesn't understand each other.
An idea how to solve this?
maybe see http://forum.yate.ro/index.php?topic=1201 for more details.
Firmware is snom715-SIP 220.127.116.11
which firmware version are you using ?
Could you please describe better the issue ? Do you see some errors on the phone ? Does the call gets established ?
