Hi Bogan I got some more success yesterday with it -- I'll post my configs after, for a SIP-I to SIP gateway.
Where I'm stuck now - there seems to be some differences between ANSI + ITU. I've got the invite coming into Opensips, then I'm successfully adding the SDP info for ISUP. (Whomever came up with this... crazy!) The far end carrier always drops the calls 483 Incomplete address. Working with the vendor the carrier, they suspect its in the User service information - They want something like this: User Service Information Mandatory Parameter: User service information (29) Pointer to Parameter: 3 Parameter Length: 3 User service information (-> Q.931 Bearer_capability): 8090a2 1... .... = Extension indicator: last octet .00. .... = Coding standard: ITU-T standardized coding (0x0) ...0 0000 = Information transfer capability: Speech (0x00) 1... .... = Extension indicator: last octet .00. .... = Transfer mode: Circuit mode (0x0) ...1 0000 = Information transfer rate: 64 kbit/s (0x10) 1... .... = Extension indicator: last octet .01. .... = Layer identification: Layer 1 identifier (0x1) ...0 0010 = User information layer 1 protocol: Recommendation G.711 u-law (0x02) Is there any way to customize this in OpenSIPS?
