Abacus: Does Abacus SIP support number portability parameter?



Customer is testing SIP with number portability. With that, there is parameter: npdi added to the Request URI line. Abacus does not reject the call. However, the responses are delayed and randomly causes path confirmation error.



The answer is no. Abacus does not support that. If there is a npdi parameter added to the Request line, the call will not be processed correctly. On the signaling side, all responses will be delayed (depending on the load). On media side, user will get no path confirmation error randomly.
