I’ve to configure my softswitch to support number portability with Asterisk.
This is how i am thinking.
SSW will receive the call, it will send the call to asterisks, ast will look in database and will send back the SIP 302 release cause (temporary moved) and the new modified number. SSW will re send the call according to new number.
In above scenario, between SSW and Ast* only signalling will be used, i.e. without any media.
at this point i am not sure how to send back 302 with new modified number, as far i searched, we can send back the number by changing sip header contact.
Any help would be really appreciated.
PS: Is there any better option to get this solution?
Thanks in advance
