Cisco SPA112 will not register with Avaya IP Office rel 10.1

[rkampling@asiowa.com]

OK, I'm brand new to this forum, so if this is the wrong one, somebody please direct me.

I have recently installed an Avaya IP Office R10.1, and I have used the Cisco SPA112 before successfully in order to connect analog devices using a SIP extension. However, These two devices seem to not like each other. I have set things up exactly how documentation from both manufacturers instructs. That documentation may be a little outdated, and I know that AVAYA has greatly increased security requirements. If I had to guess, I would say that has something to do with my troubles. Can anyone give me any up to date instructions? Thank you in advance.

You created it in wrong forum, I has moved it to more appropriate one.

While I'm familiar with SPA112 a lot, I have no experience with Avaya IP Office. Fortunately, issue can be analyzed regardless the peer vendor/model/version sometime. Just catch SIP dialog packets exchanged between  SPA and Avaya. It may disclose something helpful ...
