With this parameter, the parallel forking could be turned off, but the second phone will not be contacted. One solution here would be to implement some sort of serial forking: - asterisk will make a 'paging' call to kamailio - kamailio will perform a lookup() and it will send the call the the firs binding address - once the call is answered, asterisk should place a second call to the same account - kamailio will perform a lookup() and it will send the call the the firs binding address and it will get busy, then it will fail-over to the next binding address. - and so on ... This is kind of ugly ... but it may work You need to have individual calls between asterisk and each paged phone in order to have proper media to work. I don't think asterisk can send multiple rtp streams for the same call. Or some other hack wold be to set up aliases on the asterisk server for each binding account and make a call for each one of them. In the kamailio server, revert the alias to the true account and perform a lookup. Once you get the list or bindings, for each individual call you drop all the branches that are not matched and keep the one that matches the alias. Let's say, on the kamailio server you have the user 'paging' and there are 3 binding URIs: - paging-location1 - paging-location2 - paging-location3 On the asterisk server, three calls are setup to: - paging1 - paging2 - paging3 When the call is received, for each call a lookup will be performed for paging. For each call we kow the original RURI and we will extract from it the location that we want to call. The call for "paging1" will pick "paging-location1", the call for "paging2" will pick "paging-location2" and so on ... Anyway, you can't solve this issue with a single call from asterisk unless you have some rtp-replicator somewhere in the middle to fork the rtp stream from asterisk and let one single rtp stream to go back to asterisk.
