/usr/bin/ld: cannot find -lmysqlclient - Compiling from source

While compiling an application from source, the following error was encountered.

/usr/bin/ld: cannot find -lc
Process exited with status 1.

The problem was that the MySQL client library files didn't have soft links created for 'libmysqlclient' to the /usr/lib directory

The default installation created 'libmysqlclient.so.16'.

So inorder for the compilation to work, a soft link for this was created using

ln -s /usr/lib/libmysqlclient.so.16 /usr/lib/libmysqlclient.so

Dialing extension on a remote Asterisk Server through IAX trunk

Open the config extensions_additional.conf

Go to the context of the concerned IVR.

add the Line

exten => _<Dial Pattern>,1,dial(iax2/<Trunk Name>/${EXTEN})

eg: exten => _5xxx,1,dial(iax2/OFFICE3/${EXTEN})
When this is done, a pattern with 5 followed by 3 digits ,ie, an extension will be forwarded to the remote asterisk server using IAX2 trunk

So that an extension of an elastix server can be dialled from a remote server.

Once the file is edited

Reload asterisk.
