Sorry, I am not sure to understand the question. If you want to encode an ISUP IAM message, then, it's a matter of filling the InitialAddress
object with your expected values:
In [1]: from pycrate_mobile.ISUP import *
In [2]: print(InitialAddress().show())
### InitialAddress ###
<CIC : 0>
<Type : 1 (Initial address)>
### NatureConnectionInd ###
<spare : 0x0>
<EchoControlDeviceInd : 0 (incoming echo control device not included)>
<ContinuityCheckInd : 0 (continuity check not required)>
<SatelliteInd : 0 (no satellite circuit in the connection)>
### ForwardCallInd ###
<ISDNUserPartPrefInd : 0 (ISDN user part preferred all the way)>
<ISDNUserPartInd : 0 (ISDN user part not used all the way)>
<EtoEInfoInd : 0 (no end-to-end information available)>
<InterworkingInd : 0 (no interworking encountered (Signalling System No. 7 all the way))>
<EtoEMethodInd : 0 (no end-to-end method available (only link-by-link method available))>
<InternatCallInd : 0 (call to be treated as a national call)>
<ReservedNationalUse : 0>
<spare : 0>
<SCCPMethodInd : 0 (no indication)>
<ISDNAccessInd : 0 (originating access non-ISDN)>
<CallingPartyCat : 0 (calling party's category unknown at this time (national use))>
<TransmissionMediumReq : 0 (speech)>
### Pointers ###
<Ptr0 : 2>
<Ptr1 : 0>
### CalledPartyNum ###
<Len : 2>
### CalledPartyNum ###
<OE : 0 (even number of address signals)>
<NAI : 1 (subscriber number (national use))>
<INN : 0 (routing to internal network number allowed)>
<NumPlan : 0 (spare)>
<spare : 0x0>
<Num : >
### Opt ###
Then, calling the to_bytes()
method to encode it into a buffer.
If your question is related to something else, e.g., where you can connect to a telecom routing point, then I can't answer.
i have my own telecom routing point but i want to build a sigtran stack(sctp , M2PA , mtp3, isup) and send it to my telecom routing point
So you can use Linux + https://github.com/P1sec/pysctp for SCTP https://github.com/P1sec/pycrate/blob/master/pycrate_mobile/SIGTRAN.py for M2PA and MTP3 https://github.com/P1sec/pycrate/blob/master/pycrate_mobile/ISUP.py for ISUP. Go through the readme and wiki, read the source code eventually. Then you will be able to develop the application you need with Python.
where can i find m3ua
how can I work with isup to send iam message to Network mobile ?
