Call transfer feature in a2billing
£20-250 GBP
Оплачується при отриманні
I have a fully working PBX based on asterisk/FreePBX and a2billing.
I would like to enable blind and assisted call transfer between sip peers registered to a2billing
(not FreePBX extensions) and to mobiles and landlines via transit providers.
As my voip customers are using different SIP clients it is too difficult to have one universal settings for
all of hardware/softphone types so I think that the best way would be to use the feature codes (DTMF). If you
have other views please share.
These features codes are present in FreePBX but, as far as I know, they can only be used by FreePBX extensions.
I am not using these extensions as one ext nr, say 500, can only be assigned to one company, it is not
possible to have 500 used by another company.
The way we implemented extension dialing is alias - every outgoing call from voip customers to 3 or 4 digit
numbers goes via
an agi script that does a lookup in a new table in the db. If it finds the ext assigned to the callers a2b
account it changes the TO SIP header and replaces the ext nr with a2b SIP USERNAME and sends to a2b.
The billing should be accurate - ext to ext is free and the transferring party a2b account should be charged
when transferring to off net numbers as per existing rate cards.
In case of blind transfer the caller id should be the same as the calling party cli
(the person thet called into the company from a mobile or landline), in case of assisted call transfer cli
should be the same as the
party that did the transfer (in case of ext to ext transfer it should be the ext nr of the party that did
the transfer, in case of the transfer to off net nr the cli should be the a2b DID assigned to the
transferring party).
I need to have a full visibility of the change to be able to implement it to the new servers in the future.
