[OpenSIPS-Users] dialog - failed to get From header

[Jeff Pyle]

Hi Bogdan,

With the callid I should be able to find at least the correct dialog in
sip_trace, but printing the From header would be helpful as well.  I'll wait
to receive your reply before I apply this patch.  Regardless I won't be able
to restart the proxy until this evening when the traffic subsides.


Thanks,
Jeff
