[Freeswitch-users] How to overwrite Q850 errors code in freeswitch?

[Raviram Chandran]

Since we have a errors code in PSTN call (IP -PSTN call) which we wanton
our telephony server to pass those errors code directly to mobile apps.

Presently error codes are configured at network provider end which we need
to pass from our telephony server to mobile apps
Any help will be appreciated
