We are looking for a SS7 VoIP Expert to help us building a SS7 interconnection solution with the major local telecom operators, both fixed and mobile. We have acquired a CISCO AS5400 with 16 PRI interfaces, so one of the options would be to use the PGW 2200, but we lack both the know-how and the software, need help in both. We also consider alternatives (Sangoma, Squire, jss7, chanss7, openss7), but having the Cisco AS5400 already bought, we would like to integrate it and make use of its E1 interfaces.
