Documentation:

7.3. is_in_profile(profile,[value])

Checks if the current dialog belongs to a profile. If the profile supports values, the check can be reinforced to take into account a specific value, if the dialog was inserted into the profile for a specific value. **If no value is passed, only the membership of the dialog in the profile per se is checked.** Note that if the profile does not support values, the value parameter will be silently discarded.

Code:

``` static int w_is_in_profile_helper(sip_msg_t *msg, struct dlg_profile_table *profile, str *value) { if (profile->has_value) { if (value==NULL || value->len<=0) { LM_ERR("invalid value parameter\n"); return -1; } return is_dlg_in_profile( msg, profile, value); } else { return is_dlg_in_profile( msg, profile, NULL); } } ```

Expected result: Documentation should be corrected, or even better, code should be updated to perform as documented.
