T23G Multiple SIP accounts on Multiple SIP Servers

[sjit]

So, after some more troubleshooting I have some further info on this issue, and I believe I have discovered a bug.

It seems the issue is related to the fact that accounts on both phone systems share the same username (extension). Just to clarify, I have 2 phone systems with separate IP's that I am configuring in Account 1 and Account 2 on the Yealink T23G. If the "User Name" field in the Account setup is the same (21174 in my example above), the phone does not even try to register the second account (confirmed via asterisk -rvvv) and the phone states "Registration Failed". I can register to either SIP server one at a time (by Disabling Account 1 or Account 2). Or I can register to both SIP servers at the same time provided they have different entries in the "user name" field.

Hope that makes sense. Would really appreciate any assistance on this.

Thanks!
