I don't think SER can act as a 3pcc because it does not have a full SIP stack and it is not able to act as a b2bua(which is what a 3pcc mainly is). Moreover, since it is not a call statefull proxy is hardly impossible to add several functionalities for a SIP entityy to work as a 3pcc. my 2 cents, Samuel. Unclassified. I havent looked at the code below, but th MWI works if the phone is registered in asterisk, if the phone is registered in SER, then MWI in asterisk needs to send a message back via ser to the phone to make its light flash. As for the call being in asterisk, what I mean is if the rtp stream is in asterisk, then when you press keys asterisk can detect these, and based on keystrokes be able to do what you wish. Doin this in SER I dont think is possible since it works on SIP messages as opposed to keystrokes (which come as part of the RTP stream, having said that I do believe some IP phones can be set to send these outside using SIP INFO (I havent tested this)), and hence when you use hold/transfer and all the rest they should send a MESSAGE which SER can recognise, else it will just be buttons you are pressing which do little, if you have transferred the cvall to asterisk, asterisk should recognise and act on it.
