Summary:                    after udp error sip phones get kicked
Description: 
I get the following error message;

udptl.c:766 calculate_far_max_ifp: (no tag): Cannot calculate far_max_ifp
before far_max_datagram has been set.

udptl.c:725 calculate_local_max_datagram: (SIP/0887865299): Cannot
calculate local_max_datagram before local_max_ifp has been set

astobj2.c:116 INTERNAL_OBJ: bad magic number 0x0 for 0x227bfb8


The fax does arrive at the destination, but strangely all my sip phones
get kicked and unregister. 

I have to restart asterisk do get the sip phones back to register

I've set in sip.conf under global;

t38pt_udptl = yes,fec,maxdatagram=400
