[Freeswitch-users] Packet Fragmentation

Using Freeswitch 1.2 on UBUNTU 12.04 and working well except there is one telephone number which I cannot call. When I reported it to our VOIP supplier he found that for that telephone number we have fragmented packets. Below is his comments. How can I fix this in Freeswitch. I do not know where to make the change. Thanks Hi,

From what I can see, there is fragmentation when trying to call the number. The packet size is 1514 bytes where the data is 1480 bytes. Also, your system sends this is the INVITE:

X-Serialnumber: 0004134129BA P-Key-Flags: resolution="31x13", keys="4" which could be removed to lower the packet size.
