|max\_layer|[int](../types/int.md) | Yes|



### Type: [PhoneCallProtocol](../types/PhoneCallProtocol.md)


### Example:

$phoneCallProtocol = ['_' => 'phoneCallProtocol', 'udp_p2p' => Bool, 'udp_reflector' => Bool, 'min_layer' => int, 'max_layer' => int];
```  

[PWRTelegram](https://pwrtelegram.xyz) json-encoded version:

```
{"_": "phoneCallProtocol", "udp_p2p": Bool, "udp_reflector": Bool, "min_layer": int, "max_layer": int}
```

```
phoneCallProtocol={_='phoneCallProtocol', udp_p2p=Bool, udp_reflector=Bool, min_layer=int, max_layer=int}

```
