# راهنمای تنظیمات Callback AGI
تمام تنظیمات اجرای برنامه در فایل
[`src/main/resources/application.properties`](src/main/resources/application.properties)
قرار دارد. این AGI به هیچ پارامتر خط فرمانی نیاز ندارد.
## تنظیمات اصلی برنامه
| پارامتر | توضیح |
|---|---|
| `spring.application.name` | نام برنامه Spring است. |
| `spring.main.web-application-type` | برنامه را در حالت غیر وب اجرا می‌کند، چون این پروژه یک AGI برای Asterisk است. |
| `debug` | حالت debug مربوط به Spring Boot را فعال یا غیرفعال می‌کند. |
## تنظیمات لاگ
| پارامتر | توضیح |
|---|---|
| `logging.level.root` | سطح پیش‌فرض لاگ‌های برنامه. |
| `logging.level.org.springframework` | سطح لاگ Spring Framework و Spring Boot. |
| `logging.level.org.hibernate` | سطح لاگ Hibernate و JPA. |
| `logging.level.com.zaxxer.hikari` | سطح لاگ connection pool مربوط به HikariCP. |
## تنظیمات دیتابیس و JPA
| پارامتر | توضیح |
|---|---|
| `spring.datasource.url` | آدرس اتصال JDBC به PostgreSQL. |
| `spring.datasource.username` | نام کاربری PostgreSQL. |
| `spring.datasource.password` | رمز عبور PostgreSQL. |
| `spring.datasource.hikari.maximum-pool-size` | حداکثر تعداد connectionهای موجود در pool. |
| `spring.datasource.hikari.connection-timeout` | حداکثر زمان انتظار برای گرفتن connection از pool، برحسب میلی‌ثانیه. |
| `spring.jpa.hibernate.ddl-auto` | نحوه مدیریت schema دیتابیس. مقدار `none` مانع تغییر schema موجود توسط Hibernate می‌شود. |
| `spring.jpa.open-in-view` | باز نگه داشتن EntityManager در لایه وب. برای این پروژه غیرفعال است، چون برنامه وب نیست. |
| `spring.jpa.properties.hibernate.jdbc.time_zone` | منطقه زمانی مورد استفاده JDBC و Hibernate برای timestampها. |
## تنظیمات Asterisk و IVR
| پارامتر | توضیح |
|---|---|
| `callback.agi.dial-prefix` | پیشوند کانال برای تماس با داخلی کارمند؛ مانند `PJSIP/` یا `SIP/`. |
| `callback.agi.dial-timeout-seconds` | مدت زمان زنگ خوردن داخلی برحسب ثانیه. |
| `callback.agi.ivr-context` | نام context مربوط به IVR اصلی در dialplan. |
| `callback.agi.ivr-extension` | extension مقصد در context مربوط به IVR. برای تماس ورودی معمولاً `s` است. |
| `callback.agi.ivr-priority` | priorityای که اجرای IVR از آن شروع می‌شود. |
در شرایط زیر تماس به IVR منتقل می‌شود:
- قابلیت callback غیرفعال باشد.
- callback مناسبی برای مشتری پیدا نشود.
- داخلی پاسخ ندهد.
- در جست‌وجو یا اتصال به دیتابیس خطایی رخ دهد.
مقصد IVR از ترکیب سه مقدار زیر ساخته می‌شود:
```text
callback.agi.ivr-context,callback.agi.ivr-extension,callback.agi.ivr-priority
```
با تنظیمات فعلی، مقصد تماس این است:
```text
from-trunk,s,1
```
اگر context شما مثلاً `company-ivr` است، مقدار زیر را تغییر دهید:
```properties
callback.agi.ivr-context=company-ivr
```
## تنظیمات رفتار Callback
| پارامتر | توضیح |
|---|---|
| `callback.agi.enabled` | فعال یا غیرفعال بودن callback. اگر `false` باشد، همه تماس‌ها مستقیماً به IVR می‌روند و جدول `tbl_cdr` بررسی یا تغییر داده نمی‌شود. |
| `callback.agi.lookback-minutes` | بازه جست‌وجوی تماس‌های خروجی ناموفق برحسب دقیقه. مقدار `60` یعنی یک ساعت. |
| `callback.agi.claim-value` | مقدار موقت ستون `tbl_cdr.target` هنگام شروع callback. این مقدار برای قفل هم‌زمانی استفاده می‌شود. |
| `callback.agi.done-value` | مقدار نهایی ستون `tbl_cdr.target` بعد از پاسخ داخلی. پس از آن، تماس بعدی همان مشتری به IVR می‌رود. |
## نمونه تنظیمات
### فعال بودن Callback برای یک ساعت گذشته
```properties
callback.agi.enabled=true
callback.agi.lookback-minutes=60
```
### غیرفعال کردن کامل Callback
```properties
callback.agi.enabled=false
```
در این حالت تمام تماس‌ها بدون جست‌وجوی callback به IVR می‌روند.
### استفاده از IVR متفاوت
```properties
callback.agi.ivr-context=my-ivr
callback.agi.ivr-extension=s
callback.agi.ivr-priority=1
```
### تغییر بازه جست‌وجو به ۳۰ دقیقه
```properties
callback.agi.lookback-minutes=30
```

# Callback AGI
این پروژه یک AGI برای Asterisk است که قبل از IVR، آخرین تماس خروجی ناموفق
به مشتری را در یک ساعت گذشته پیدا می‌کند. رکورد با مقدار `target = 'pending'`
به‌صورت اتمیک قفل می‌شود؛ در صورت پاسخ داخلی، مقدار آن به `callback_done`
تغییر می‌کند و در غیر این صورت قفل آزاد شده و تماس به IVR می‌رود.
## ساخت و نصب
```bash
./mvnw package
install -m 0755 scripts/callback-agi /var/lib/asterisk/agi-bin/callback-agi
```
مسیر JAR را با متغیر `CALLBACK_AGI_JAR` تنظیم کنید. اسکریپت باید در نقطه ورود
تماس ورودی به‌عنوان AGI موجود نصب شود؛ خود پروژه نیازی به تغییر dialplan ندارد.
برای اجرای محلی از ریشه پروژه، wrapper به‌صورت خودکار JAR داخل `target/` را
پیدا می‌کند:
```bash
./mvnw clean package
printf 'agi_callerid: 09121234567\nagi_dnid: 02112345678\n\n' | ./scripts/callback-agi
```
این برنامه یک AGI غیر وب است و بدون آرگومان اجرا می‌شود. برنامه ورودی AGI را
از stdin می‌خواند و تنظیمات آن از `application.properties` خوانده می‌شوند.
```bash
./mvnw spring-boot:run
```
## تنظیمات
تمام تنظیمات در فایل
[`CALLBACK-CONFIG.md`](CALLBACK-CONFIG.md) مستند شده‌اند.
مقادیر را مستقیماً در `src/main/resources/application.properties` تغییر دهید.
مقدار `agi_callerid` نرمال می‌شود؛ پیشوندهای `+98`، `0098` و صفر ابتدایی،
فاصله و خط تیره حذف می‌شوند. `agi_dnid` برای ثبت رکورد لازم نیست و برای
تطبیق callback عمداً استفاده نمی‌شود.
## نکات دیتابیس
برای سرعت lookup، در صورت امکان migration زیر را اجرا کنید:
```sql
CREATE INDEX IF NOT EXISTS idx_callback_lookup
ON tbl_cdr (real_dst, calldate DESC)
WHERE direction_call = 'outbound'
AND disposition IN ('NO ANSWER', 'BUSY', 'FAILED');
```
ستون `target` باید nullable باشد. نام و رمز عبور دیتابیس را در source code
قرار ندهید.
