[SR-Users] SIP-I trunking

Hello, I'm planning to interconnect kamailio with a SIP-I provider (an i have no more information at this time from my telco). I read the documentation about the SIP-I module, who need to be completed to match our needs. basically, we need to read the location parameter for incoming call, and be able to set redirecting number for outgoing call Does anybody use this module for SIP-I ? Have you experiences of SIP-I trunking with telco ? And another question: when you make an ISUP (SS7) interconnection with a telco, you need to pass specific test to validate the correct implementation of the SS7 protocol (and it's national variant, eg. SPIROU in france). Is it the same thing on an SIP-I interconnection ? Any information about it will be appreciate, Cheers, Jérôme.
