要根据呼叫发起的位置发送电子邮件，您可以使用Asterisk的AGI（Asterisk Gateway Interface）功能和Python脚本。下面是一个示例代码解决方法：

1. 首先，创建一个Python脚本来处理电子邮件发送逻辑。假设您已经安装了Python和相关的邮件库（例如smtplib）：

#!/usr/bin/env python
import smtplib

def send_email(sender, receiver, subject, body):
    smtp_server = 'your_smtp_server'
    smtp_port = 587
    smtp_username = 'your_smtp_username'
    smtp_password = 'your_smtp_password'

    message = f'From: {sender}\nTo: {receiver}\nSubject: {subject}\n\n{body}'

    try:
        server = smtplib.SMTP(smtp_server, smtp_port)
        server.starttls()
        server.login(smtp_username, smtp_password)
        server.sendmail(sender, receiver, message)
        server.quit()
        print('Email sent successfully!')
    except Exception as e:
        print(f'Failed to send email: {str(e)}')

# Example usage:
send_email('sender@example.com', 'receiver@example.com', 'Test Email', 'This is a test email.')

2. 接下来，创建一个Asterisk AGI脚本，以调用上述Python脚本并传递所需的参数。假设您已经安装了Asterisk和AGI脚本所需的库（例如python-agi）：

#!/usr/bin/perl
use strict;
use warnings;
use Asterisk::AGI;

my $agi = new Asterisk::AGI;

my $caller_id = $agi->get_variable('CALLERID(num)');
my $caller_location = 'unknown';  # 根据CALLERID(num)获取呼叫位置

my $email_sender = 'sender@example.com';
my $email_receiver = 'receiver@example.com';
my $email_subject = 'Call Location Information';
my $email_body = "Caller ID: $caller_id\nCaller Location: $caller_location";

my $command = "/usr/bin/python /path/to/email_script.py --sender='$email_sender' --receiver='$email_receiver' --subject='$email_subject' --body='$email_body'";
my $result = `$command`;

print $result;

请根据您的实际需求和环境，将示例代码中的SMTP服务器和身份验证凭据替换为正确的值。另外，确保将Python脚本和AGI脚本中的路径替换为正确的路径。

以上是一个示例的解决方法，您可以根据自己的需求进行修改和扩展。
