Description

Language in which Calling Card is played can be set in several places by such priority:

Explanation

By default language is en, it is set in /etc/asterisk/sip.conf as language = en

If Calling Card does not use IVR and DID language is set to empty, then default language will be used.

This image shows how to set to use default language (when IVR is not used and when DID has empty language):

If Calling Card Dial Plan (DP) is using IVR, then language set in IVR overwrites Default Language and is used IF DID language is empty.

This picture shows how Language (Voice) is set in IVR:

This example changes Language to es (Spanish).

Once again: it overwrites default Language (en) only when DID Language is empty!

And the most important is DID Language, which can be set in used DID:

This example shows ru language which will be used no matter what is Default Language and no matter which Language (Voice) is set in IVR.
