Hello, After having worked with ser for a few days, I have SER running with authentication, accounting , voicemail and conferencing, which is working great (Thanks for this great product). However, I have a problem connecting Cisco 7960 phones. Ser server: colo.foo.bar. Domain/authentication realm/alias: foo.net. In my grandstream phones I can configure a different domain then the sip proxy. In the cisco phones, I can only configure the sip proxy. The cisco's are registering with the username(a)colo.foo.bar and not with username(a)foo.net. The phones will not authenticate, because there only exists a username(a)foo.net in the database. What is the best to solve this problem. I can think of the following: - match the uri and do: rewritehost("foo.net") - make a srv entry for foo.net pointing to colo.foo.bar and set the proxy in the cisco phone to foo.net - configure multidomain support and put in both domains. I'm not sure what the best solution is, does anyone have experience with this issue? Furthermore, I have a question of which I could not find an answer for in the archives or google. Is it possible to do call pick-up with ser? My first thought would be no (and use a timeout with forwarding), because Ser is not call statefull (and has no b2bua). But maybe I'm wrong. Kind regards and thanks for reading, Geert Nijpels
