Hello I have trouble with number dialed starting with + CDRTool doesn' understand it. So I have to strip it from the request and replace it by 00! The problem is that even using this at the begenning of OpenSER script, it's not working (see CDRTool log below)
Any idea how to solve it? Thanks

Hi Marc,
had the same issue. The problem is that CDRTool supports only one type of international prefix (in your case any of '00' or '+', so no way of specifying two). The reason you cannot replace + with 00 before authentication is that the full digest-nonce is calculated based on a series of factors (which includes original from and to uris and replacing to_uri before sending the request to radius to be authenticated would mean that radius will never recognize the nonce to be valid anymore).
There are two ways of fixing your problem, as I see them (and mines too): 1. CDRTool folks should support some sort of list of international prefixes recognized and stripped. 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.
Cheers, DanB

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')
But I don't understand how to change the second part in OpenSER?
Otherwize I will do it in the accounting python module?
Thanks!

I have changed this in the accounting Start part! It a little bit dirty but it works...
#can_uri = atrbValue(params, 'Canonical-URI') can_uri = atrbValue(params, 'Canonical-URI').replace('+','00')

Marc,
just to avoid unnecessary processing, I would say the patch for the connector should look like: (authorize function, right after if MULTIPLE_PREPAID_ENGINES block
# Patch for the digest uri starting with + (openser is not able to touch that, and cdrtool not able to recognise) if to_uri.find('+') != -1: log(1, 'destination containing +, will replace it with 00...') to_uri = to_uri.replace('+', '00')
res_newsession_raw=client_prepaid.new_session(username, to_uri, SESSION_MAXDUR)
In OpenSER, I have done the following, right after radius_proxy_authorize call:
if (!radius_proxy_authorize("")) { proxy_challenge("","0"); exit; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); exit; };
if (uri=~"^sip:+.*@"){ strip(1); prefix("00"); xlog("Changed RURI due to +, new one is: $rU"); };

Yes, I revised the PHP code and it's not possible to set "+" as international prefix, just numbers :(
Please, don't change the "To", it's not necessary at all !
CDRTool looks for the Canonical-URI radius attribute, and you don't set it. Note that in "radius_extra" you set "Canonical-URI=$avp(to_destination)", so add this after RURI transformation ("+" -> "00").
$avp(to_destination) = $ru;
Just it.

RealTime billing is ok, but after there is still '+' in radacct table in Canonical-URI and called-Station, so when CDRTool Normalize the radacct table avery 5 minutes, CDRTool failed to calculate the price!
The strip / prefix functions replace correctly the URI field, but it doesn't change the Canonical-URI, I have tried to change the Canonical-URI with $ai, but it doesn't work Is is possible to stip char in avp??
Have a nice afternoon

I don't understand the reason you can't change Canonical-URI, jsut do it:
### Canonical-URI for CDRTool: $avp(AVP_CANONICAL_URI) = $rU + "@" + $rd; avp_subst("$avp(AVP_CANONICAL_URI)", "/^+/00/"); xlog("L_INFO","--- CanonicalURI = $avp(AVP_CANONICAL_URI) \n");
