Hello,
If the UDP packet is fragmented and due to whatever reasons the UA
doesn't receive it properly, there are a couple of things that you can
do to reduce the SIP message size :
1 - enable topology hiding in OpenSIPS ( see
http://www.opensips.org/html/docs/modules/1.11.x/dialog.html#id296413 )
2 - manually remove optional headers from the OpenSIPS script (
http://www.opensips.org/html/docs/modules/1.11.x/sipmsgops#id293936 )
3 - remove some of the codecs from the SDP (
http://www.opensips.org/html/docs/modules/1.11.x/sipmsgops#id294821 )
Also, another alternative would be to switch to TCP in order to avoid
these fragmentation issues.

In the first case the last UDP packet (INVITE with authentication
header) is fragmented.
It's very common to lost fragmented UDP packet.

Hi all,
i'm experiencing a strange issue. Some VoIP phones, like mine (5002),
cannot call other phones (like 5023) but i receive calls from 5023. Same
config, same context.
I did some sipgrep:
Call from 5002 to 5023 (FAILED):http://pastebin.com/BF6YyWHr
Call from 5023 to 5002 (SUCCESS):http://pastebin.com/rW3AKr22
My config:http://pastebin.com/9gP9xncd
Thanks for all your help.
Michele
