Hello,
my guess is, you have a problem with udp/ip fragmentation. You reinvite is much larger then the initial invite (~1200 vs 1600 Bytes). Talk to your provider so he can fix his firewall or other settings. Alternative ask for a switch to TCP.
As a last resort, you can try to reduce the size of the reinvite somehow. Like removing not neccessary SIP header or codecs from the SDP.
