Hello Guys,

I’m trying to integrate Ser with asterisk.

Asterisk server resides on private network behind router. All UA’s are on the same internal network with Asterisk server and registered with it.

Asterisk server registered with Ser server, so this way I get incoming calls without any problems. At the same time when on of UA’s trying to call out

Ser server gives 407 errors Authentication Required. I cannot add asterisk server into my trusted table because ADSL connection has Dynamic IP which may change frequently.

This message I receive, because in INVITE part I have UA in FROM: field witch are registered with asterisk not SER. How can I resolve this issue for outgoing calls?

Thank you for your help and sorry for bad English

Regards

Alex Fler
