PAOK1926 Please, is for all process install vtiger7 in issabelpbx. for future users. thanks.

PAOK1926 can you tell me how you do it? And which features now you have in vtiger? Did you buy any addons to vtiger?

This is process I used to install vtiger5 (depreciated but it is a starting point for people) in Issabel and get some proof of concept connection between the two applications.

PAOK1926 I had a problem, Vtiger 5 is working perfectly, but there is a problem, it is not possible to import any .csv files, could you do that?

Here's some instructions how to install Vtiger7.1.0 into ISSABEL.
This is NOT upgrade. This is new install only.

dickson muy suficiente he instalaba Vtiger con tu ayuda fui facil, solo falta como configurarlo con issabel ?

Sorry. I did not integrate asterisk with VTIGER using SIP. I used asterisk dialplan SQL commands to connect Vtiger.

Example:

exten => s,3,MYSQL(Query resultid ${connid} SELECT ticketid FROM vtiger_troubletickets WHERE ticket_no = ${ticketnumber})

Some more details on that type of integration:

when I create a user from vtiger with the admin this does not let enter indicate username and password error
