[sr-dev] SIP-I ?

Hi list this may sound like and old ugly topic, but at the end of the day most of the traffic still starts/terminates in TDM networks. For those not familiar with it, the IPX (http://en.wikipedia.org/wiki/IP_exchange) mandates the usage of SIP-I between operators for transporting the call information over SIP. Kamailio is the core component of our infrastructure, and in order to route traffic between these kind of operators we might need to "understand" somehow SIP-I. So this is more or less like an open question: do you think it makes sense to write a kamailio module for decoding/encoding ISUP/MAP traffic, or do you think it fits better in another type of equipment closer to the "TDM border" (Yate, Freeswitch,...). Thanks in advance Javi
