[SR-Users] Kamailio 5.3.0 and HEPv3 oversized traffic

Thu Jun 4 22:59:33 CEST 2020

Hi Henning,

Sorry for the typo. It's an testing 5.2 to 5.3.4 conversion not fully
tested.

I don't checked the change from a to b version document, is there an hint
for all the useful and needed changes we discussed here?

Will check the input from today tomorrow.

Cheers
Karsten Horsmann
