[cisco-voip] SIP proxy + Cisco PSTN gateway

[Dmitry Semyonov]

Hello.

Is it possible to use Cisco AS5350 alone as SIP-PSTN gateway to
provide connectivity between SIP and PSTN users via SIP proxy
(e.g. SER), or PGW2200 is required as well?

As I understood from various sources of information, PGW2200 should
(must?) be used when SS7 signaling is utilized. In the case of PRI or
CAS signaling, AS5350 is enough. Am I right? Thanks.


...Bye..Dmitry.
