UCM6208 sip out fails in bound works


#1

Here is my firewall rules and a dump.

Worked with the sip provider who says they send back a 407 and the grandstream doesnt see it (dump). What is my next move, battled this hard.

fixed. the MTU was to small. Ran a dump on the outbound calls saw it was dropping part of the packet wehn sending to known traffic
