We had the same problem with SDP.
There are very many UA with this mistake error
To bypass this restriction we have added after
force_rtp_proxy();
Also such command
subst("/^c=IN IP4 ([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)(.*)/c=IN IP4
11.22.33.44\5/i");

Subject: [Users] Overlapping AVPs
To: [email protected]
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi,
Me again, sorry, but the docs aren't really noisy about AVP details...
So if I have user preferences for both the caller and callee and load
them from DB and print them using the following:
avp_db_load("$avp($uuid_caller)", "");
avp_db_load("$avp($uuid_callee)", "");
avp_print();
then they may overlap because of the same ID (say "i:102" for toggling
some specific feature on/off), but according to the debug output both
are present:
INFO:avpops:print_avp: p=0x4056db90, flags=100
INFO: id=<102>
INFO: val_int=<1>
INFO:avpops:print_avp: p=0x4056dc68, flags=100
INFO: id=<102>
INFO: val_int=<0>
So is it possible to selectively access the avp-value of both
$uuid_caller and $uuid_callee? Something like $avp(i:102)[0] and
$avp(i:102)[1] maybe?
Thanks,
Andy

Hi Bogdan, I'm trying to setup my config file , did the same
modparam("avpops", "db_scheme",
"scheme0:username_col=from;value_col=timestamp;value_type=string;table=a
cc")
modparam("avpops","avp_aliases","timestamp=i:800")
if (method=="INVITE")
avp_db_load("$from","$timestamp/$scheme0");
I'm not sure that is correct...
log gives me these errors
Apr 11 08:42:59 localhost /usr/sbin/openser[13752]: submit_query: You

Any thought?
