I am having problems getting an Aastra 57i to make calls through FS. the phone registers fine, but all calls fail. If i use xlite or a nokia sip phone, i have no problems.
Here is a packet capture of an attempted call:

notice packet 9, it should have been a SIP INVITE, but it turned out to be a Fragmented IP protocol
The phone and FS are both on the same lan subnet, and the phone connects fine with an asterisk server on the same subnet.
Is there a known config for aastra phones that I can reference, or does anyone know why I am having this issue?

Figured out the phone was sending packets that were too large, and the receiving system was not reassembling the fragmented packet. This can be fixed on the Aastra by enabling basic codecs:

Go to the phone web-UI -- global SIP -- Codec Preference List -- Codec 1 -- change all to basic, save settings and restart the phone.
Or in cfg files for aastra set:
sip use basic codecs: 1
