***Toll-Free not working***

[Zekeria Sammantar]

Hi Everyone,

I'm facing an issue when I try to call a toll-free number like (800-700-8000) but when I try to call 907 it works.

Both the Toll-free and Service numbers use the same dial-peer

I received the below message from the interface connected to SIP Provider

SIP/2.0 480 Temporarily Unavailable

Edge Interface to Sip-Provider = 172.29.26.238

Y.Y.Y.Y = CUCM

Z.Z.Z.Z = CALLING NUMBER

P.P.P.P = IP ADDRESS FOR SIP PROVIDER

8007008000 = Called Number

dial-peer voice 9 voip

translation-profile outgoing OUTCALLS

destination-pattern 9.T

session protocol sipv2

session target ipv4:P.P.P.P

incoming called-number .

Thanks

Llikely you need to call 1800xxxxxxx. Or ask ITSP.

Hi Paolo,

This setup is located in Saudi Arabia

so the toll number here is

• 800 XXX XXXX - Toll free

The issue is that I dont know if the problem is from the gateway or the provider since the "SIP/2.0 480 Temporarily Unavailable" was generated from the local gateways interface connecting to the ITPS.

[paolo bevilacqua · Accepted solution]

It's from ITSP, see "Received'.

[Zekeria Sammantar]

If you look at the message :

From: 172.29.26.238>;tag=F112E48A-24F

the following ip address is from the local gateway itself (172.29.26.238), so how can I send myself the message unless the issue originate from the local gateway.

Which is confusing, if it is from the ITSP shouldn't it look like this?

Thanks Paolo It as you said

I had to check the (Call-ID)

Received:

Call-ID: 70EA31D3-DFF211E2-9B96EA94-227BC254@172.29.26.238 (Unique to ITSP)

Orginated from the ITSP
