Subject: [Freeswitch-users] ANI Source

My provider has responded to a question regarding missing caller id to some recipients and said:

Per our records we are receiving a 'null' value in the ANI/Source portion

But my log says:

[SNIP] set(ani=4104440002)

0d29c542 – [SNIP] [DEBUG] mod_dptools.c:1598 SET sofia/internal/414@fs-esta2.bizfocused.com [ani]=[4104440002]

Any ideas?

Thanks,

Sean
