Thanks Dan and Iñaki for your answers:
I've changed this in the freeradius-cdrtool module of Dan:
#to_uri=atrbValue(params,'Digest-URI')
to_uri=atrbValue(params,'Digest-URI').replace('+','00')
2. A bit dirty patch on the freeradius-cdrtool
connector to replace "+"
with "00" in case of calls starting with +, before querying cdrtool in
auth phase. In this case you must replace also in openser + with 00 so
when the call will go out, should go with 00 (to be properly reflected
later in cdrs). - this is what I did and looks like running smooth.
But I don't
understand how to change the second part in OpenSER?
Otherwize I will do it in the accounting python module?
Thanks!
