Inbound calls for SIP trunking

[lison]

Hi, this is my first post and i really need help. I am currently working in Saudi and they decided to change the area codes from (e.g. 04 to 014). Since then our Avaya phones cannot receive incoming calls (DID-SIP Trunking) from a different area code or mobile. We did a list trace tac and here is the error, when a mobile is calling on one of our phones.

15:23:19 SIP<INVITE sip:[email protected];user=phone SIP/2.0
15:23:19 Call-ID: b541856785e5902bc199a85a840db634
15:23:19 active trunk-group 107 member 249 cid 0x1c71
15:23:19 SIP>SIP/2.0 404 Not Found
15:23:19 Call-ID: b541856785e5902bc199a85a840db634
15:23:19 dial 0
15:23:19 term trunk-group 107 cid 0x1c71
15:23:19 idle trunk-group 107 cid 0x1c71

Just the list trace wont give much idea. lot of reason for 404 not found. Best way to go about this to speak with a backbone engineer at Avaya and get this issue fixed.

Perhaps if you give more / clearer details of your architecture, platforms and versions, forum members might be able to assist you better.

Cheers,
