Mitel To Siemens SIP Card

[Mitel999]

Hi all,

Has anybody successfully connected directly to a Siemens ISDX using a 3540 hg IP gateway card to connect to Mitel 3300 using SIP.

I can’t see anything in the SIP interoperability on MOL

We have always connected using DPNSS in the past

If i call from a Siemens set to a Mitel there is no issue. Get the correct 100, 180, 200 BYE etc. When calling from a Mitel to Siemens get 100 Trying then Response 404. SIP/2.0 404 Not Found"


Thanks in advance
