[asterisk-users] how asterisk knows which context forward the call to?

[Joseph]

I think you are correct, thank you for pointing it out.

I just switch entries in sip.Cong put [pstn-9998] "first' and [pstn-4444] "second"
and the second entry was selected :-( (so you are right on).
Audiocodes gateway, has two FXO ports, I was convinced that entry is selected based on registration context in [square-bracket] of sip.conf but it 
doesn't appear to be the case; the last registered entry is selected as default.

Is it a limitation how SIP works or asterisk limitation?
Is it possible to split registration into two different sip.conf files (sip1.conf and sip2.conf)?
