Hi Alex, Please let me make a comment here in support of Abdul Hakeem's comment in respect of Kamailio supporting a SIP to SMPP translation module and in furtherance of this thread (conversation). I believe Kamailio, as an open source community would glean the benefit of supporting a feature that could see better funded players use Kamailio, with SIP to SMPP, as an alternative strategy to supporting proprietary solutions. As networks look towards 4G technology the support of such a feature could see Kamailio used as a gateway between the origination technology and the legacy SMSC gateway. This is a solution, I believe, many will need to consider looking forward.
