Hi,

I want 've many SIP trunks from the same SIP provider, do i need to 've only one identify section in PJSIPconf ?
and how can i match an incoming call to which endpoint must end ?

Thanks

Insufficient information about your requirements.

If registering, try the line option. Otherwise look at an incoming request and talk to the provider about what information can be used.

Generally it is best to have just one account. Are you trying to use consumer accounts for resale, or a SOHO provider for a medium sized enterprise?

HI David,

I ve 2 sip trunks from the same sip provider in one PBX where the provider requires to register these trunks. i can make outbound calls but the problem is with the incoming call in any of those 2 numbers, i cannot distinguise to which endpoint the provider must send the call ? i used match_header in the identify section for each trunk based on the username of each trunk

Does the line option work?

Hi,
Any idea what might me wrong in my PJSIP.conf ?

Probably nothing. You are trying to use a provider in a way in which they don’t expect to be used.

I think match conditions are ORed, not ANDed.

(Well, actually, you have too many explicit settings, which makes it difficult to see the wood for the trees.)
