Our PBX does not need Auth Username to register or to make outbound calls. This input can be left blank (Or same SIP Username can be filled in) while configuring the account in ZoiPer App.
Imagine two users with Usernames user1 and user2 and both of these users are using ZoiPer push proxy. The problem is when user1 makes an outbound call, the Auth Username presented to the PBX is "user2" resulting in p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #000000} span.s1 {font-variant-ligatures: no-common-ligatures}
username mismatch, have <user2>, digest has <user1>
error on our PBX.
In other words ZoiPer push proxy is using incorrect (mis-matched) "Auth Username" in the outbound calls invite sent to the PBX.
I also tried with filling the Username in "Auth Username" input field in ZoiPer Account config screen (instead of leaving it blank) and still see the same username mismatch error.
Please advise. Any help is highly appreciated.
