[asterisk-users] Can not calculate far_max_ifp before far_max_datagram has been set

[Marco Capetta]

Hello,

I use Asterisk 13.1 with a SIP trunk with a provider

When transmitting or receiving a fax in T.38 through the trunk with the 
provider I always get this warning:

WARNING [8204]: udptl.c: 852 calculate_far_max_ifp: UDPTL (no tag): Can not 
calculate far_max_ifp before far_max_datagram has been set

After the warning begins exchanging packets UDPTL, but all with sequence number 
0 or 256.
The fax is not properly transmitted or received.

I configured the trunk as follow:

t38_udptl = yes
t38_udptl_ec = redundancy
t38_udptl_maxdatagram = 400

How can I fix the problem?

Thank You
Marco--

[asterisk-users] When are /proc/dahdi files created

[Michelle Dupuis]

Can someone tell me when the /proc/dahdi files are created for spans?  Are they 
created when asterisk starts (or the asterisk init script) - if not what script 
creates them?
