[OpenSIPS-Users] Using dispatcher and t_replicate()

[Jody Rudolph]

Bogdan,

I am using SVN latest 1.6 via:
svn co https://opensips.svn.sourceforge.net/svnroot/opensips/branches/1.6 opensips_1_6
I tried last week at 1.6.3 and received the errors I posted in the previous email. After 1.6.4 the error messages have changed slightly but still seems to be related.


call to function:

ds_select_dst("1", "4");
t_replicate("$du");

1.6.3 error:
>>  Dec 20 13:16:02 [12858] ERROR:core:parse_uri: uri too short: <$du> (3)
>> Dec 20 13:16:02 [12858] ERROR:tm:uri2proxy: bad_uri: $du

1.6.4 error:

Dec 22 10:18:50 [11874] ERROR:core:parse_uri: bad uri,  state 0 parsed: <<nul> (4) / <<null>> (6)
Dec 22 10:18:50 [11874] ERROR:tm:uri2proxy: bad_uri: <null>
Dec 22 10:18:50 [11874] ERROR:tm:t_forward_nonack: failure to add branches

Thanks,
Jody
