Hello,
I have Aastra phone that doesn't seems to get new firmware and most importantly NEC
Hybrid IP phones.
My question is, how can I "adjust" Kamailio to get these phones behave like SIP
compliant phone.
Which kind of Module do I have to develop? For the NEC story, I will actually dedicate a
separate Kamailio instance if some workaround is possible.
Someone offer me a complete NEC system to do this: NEC phone system + plus some NEC IP
Phones for the "reverse engineering" task. So I will be able to see all the SIP
traffic on the NEC system and will adjust Kamailio to handle them. Possible???
Thanks,
Vic

Hello Victor
your question is a bit to generic for a proper answer.
It depends how "broken" and non-compliant the custom SIP implementation is. If
its not too much broken, you should be able to fix the SIP. Have a look to the
"textops" module, to see how to replace text in a SIP message, for example.
You should be also able to use the "pseudo-variables", which many are writable
to fix things. This are documented in our wiki.
Normally you don't need to develop an own module for simple header
modifications.
If you have an issue with a certain header field or need some more help in
using the mentioned modules, just ask again on this list.
Best regards,
Henning
