Symlink from modules failed

Running Elastix 1.6.12 and FreePBx 2.8

Symlink from modules failed

retrieve_conf failed to sym link:
/etc/asterisk/sip_notify.conf from core/etc
This can result in FATAL failures to your PBX. If the target file exists and not identical, the symlink will not occur and you should rename the target file to allow the automatic sym link to occur and remove this error, unless this is an intentional customization.

We are not able to dial in or dial out but can dial internally.

The sip_notify.conf has not been modified. I heard that FreePBX 2.8 has some conflicts with Elastix. Is that true? Can I go back to FreePBX 2.7
