ผมใช้ Elastix 1.5.24 แบบใช้หลัง nat โดยเพิ่ม configure ในไฟร์ sip_nat.conf
-------------------------------------
externhost = branch.dyndns.org
externrefresh = 30
localnet = 192.168.1.0/255.255.255.0
localnet = 192.168.2.0/255.255.255.0
net = yes
-------------------------------------
ตอนนี้สามารถโทรหากันได้ครับปกติ แต่ติดปัญหาตรงหลุดค่อนข้างบ่อย รบกวนพี่ๆหน่อยครับ ผมใช้ ata 2 รุ่น
1. PAP2T <ไม่ค่อยหลุดแต่มีบ้าง>
2. SPA112 <หลุดบ่อยครับ>
-------------------------------------
ตรวจเช็คเบื้องต้น dynamic dns ที่ office หลักไม่มีหลุดไม่มีการเปลี่ยน ip แต่ตาม site หลุดครับ รบกวนพี่ๆหน่อยครับ

ประมาณนี้เลยครับพี่

ขอบคุณครับที่ให้รายละเอียดมาเยอะเลย อย่างนี้ช่วยได้สบายมาก

3 เบอร์นี้ใช่ pap2t ป่าวคับ ไม่มีปัญหา

11.606189 192.168.2.4 -> 182.53.97.47 SIP Request: OPTIONS sip:2002@182.53.97.47:5062

41.480104 192.168.2.4 -> 223.206.127.75 SIP Request: OPTIONS sip:1001@223.206.127.75:5062
41.577836 223.206.127.75 -> 192.168.2.4 SIP Status: 200 OK

ที่ไม่หลุดเพราะ asterisk (192.168.2.4) ส่ง options ไปแล้วมี ok ตอบกลับมา เลยทำให้ asterisk อัพเดทสถานะของสองเบอร์นี้ว่ายัง live อยู่ (สามารถโทรเข้าสองเบอร์นี้ได้)

มาดูอีกหลายๆเบอร์ที่เหลือ เบอร์ที่มีปัญหา

38.999731 192.168.2.4 -> 223.205.99.95 SIP Request: OPTIONS sip:1004@223.205.99.95:10006

39.999306 192.168.2.4 -> 223.205.99.95 SIP Request: OPTIONS sip:1004@223.205.99.95:10006
40.001289 192.168.2.4 -> 223.205.99.95 SIP Request: OPTIONS sip:2004@223.205.99.95:12448

มันหลุดเพราะว่า asterisk ส่ง options ไปแล้ว ทางนั้นไม่มี ok ตอบกลับมา ทำให้ asterisk คิดว่า die ไปแล้ว เลยมาร์คสถานะว่าเป็น unreachable (ไม่สามารถโทรหาเบอร์เหล่านี้ได้)

ต่อไปมาดูตัวสีแดงๆ

75.163461 223.205.97.54 -> 192.168.2.4 SIP Request: NOTIFY sip:branchitzonen002.dyndns.org
75.163618 192.168.2.4 -> 223.205.97.54 SIP Status: 489 Bad event

Asterisk ตอบกลับไปว่า 489 Bad Event ไม่ใช่เพราะว่า Asterisk ไม่รองรับ NOTIFY ความจริงคือมันรองรับ แต่ว่ามันส่งมาจาก IP ที่มันมาร์คไว้แล้วว่าเป็น unreachable

คงพอเข้าใจสาเหตุที่ทำให้มันหลุด (โทรไปไม่ได้) นะครับ มาดูวิธีแก้ปัญหากัน

1. เซ็ต register timeout ใน ata ที่มีปัญหา ให้ถี่ๆหน่อย สัก 60 พอ
2. ปิด firewall บน adsl router ฝั่ง ata ที่มีปัญหา
3. แก้ไขบรรทัด notify ในเบอร์ extensions ที่เป็น ata ที่มีปัญหา จากค่า yes เป็น no

** ทุกไซต์ใช้ adsl router ยี่ห้อเดียวกันหมดป่าวครับ รุ่นเดียวกัน เฟิร์มแวร์เดียวกัน **

ลองดูคับ วิธีใดวิธีหนึ่งหรือไม่ก็ทุกวิธีหรือไม่ก็ไม่มีวิธีไหนที่เวอร์คเลย 55+
