Hi all,

 

I need your help again.

 

Yeastar S100 On-Premise PBX

Version: 30.11.0.28 (latest)

SIP Register Trunk

T19P phones with some Linkus app

32 extensions

 

All of a sudden a client can not dial out an international number (for example 0044XXXXXXXXXX) even though on her extension Call Permission Tab an outbound route with X. is selected. She tried it on another two extensions and the same Forbidden message displayed on the phone screen so there must be something on the PBX that needs adjustment.

No problem with national numbers.

I have an ethernet capture of the call but will only send it on private for troubleshooting. I'm quite new to SIP so I need somebody who knows SIP well.

 

Thanks in advance.

  Here's more info on the Forbidden issue for the outbound international call. 

  

  Does anybody know what's the meaning of unrecongised SIP header?

  Thanks for your help.

  Hi Chad,

   

  Try to disable the Remote Party ID parameter for outgoing call on the SIP trunk page setting page.

  Thanks Riddhe for the reply.

  Did what you wrote above but the Forbidden message issue still there.

   

  See the Trunk -> Advanced Tab

  

   

  And General -> SIP -> Advanced Tab

  

  I have an S20 in the office and I will replicate the problem and see if I manage to get the right settings.

  Thanks again.

  RPID is not the issue, It is also likely not a S PBX issue,

  A 403 forbidden error is usually returned when something being sent to the provider is incorrect in the INVITE -

  It could be:

  1. Incorrect credentials in the SIP INVITE, (likely not the issue in your case)

  2. International calling is not authorized (done by most providers to prevent fraud and must be requested by the account owner)

  3. The dial strung being sent is not in the format that the provider can accept and process. You need to check with the provider to see how they need to see an international call dial string formatted.

  4. The account has not been paid.

  And others.

   

  I suspect #2 or #3 is the issue.

  Hi everyone,

   

  Just to give you an update.

  There was a call limit on the Trunk Provider side and the client reached that limit.

  So we extended the limit and the client managed to call out an international number.

  Thanks!
