Assistance Required with pjsua_call_make_call Assertion Failure
Dear PJSIP Community,
I am running the app-kotlin in the PJSIP sdk and encountered an issue with
the pjsua_call_make_callfunction while working on a VOIP dialer project
using the PJSIP SDK. The application crashes with the following assertion
failure:
.*./src/pjsua-lib/pjsua_call.c:844: pj_status_t
pjsua_call_make_call(pjsua_acc_id, const pj_str_t *, const
pjsua_call_setting *, void *, const pjsua_msg_data *, pjsua_call_id
): assertion "acc_id>=0 &&
acc_id<(int)(sizeof(pjsua_var.acc)/sizeof(pjsua_var.acc[0]))" failed
I also received the warnings in the logcat in android studio as follows:-

I have installed and built PJSIP successfully. Under the "app-kotlin"
application of PJSIP in kotlin, in the MainActivity.kt file I set the
following configurations rest remaining same:-
For client app 1:-
const val ACC_DOMAIN = "sip.pjsip.org" const val ACC_USER = "101" const val
ACC_PASSWD = "--secret--" // Peer to call const val CALL_DST_URI = "
sip:103@sip.pjsip.org"
For client app 2:-
const val ACC_DOMAIN = "sip.pjsip.org" const val ACC_USER = "103" const val
ACC_PASSWD = "--secret--" // Peer to call const val CALL_DST_URI = "
sip:103@sip.pjsip.org"
In the onCreate() method the following account and transport config:-
/* Create transports and account. / try { val sipTpConfig =
TransportConfig() sipTpConfig.port = SIP_LISTENING_PORT.toLong()
g.ep.transportCreate(pjsip_transport_type_e.PJSIP_TRANSPORT_TLS,
sipTpConfig) // Account Configuration val accCfg = AccountConfig()
accCfg.sipConfig.proxies.add("sip:$ACC_DOMAIN;hide;transport=tls") // SIP
Proxy accCfg.idUri = "sip:$ACC_USER@$ACC_DOMAIN" // Account URI
accCfg.regConfig.registrarUri = "sip:$ACC_DOMAIN" // Registrar URI //
Authentication Credentials val creds = accCfg.sipConfig.authCreds
creds.add(AuthCredInfo("Digest", "", ACC_USER, 0, ACC_PASSWD))
accCfg.videoConfig.autoShowIncoming = true
accCfg.videoConfig.autoTransmitOutgoing = true
accCfg.videoConfig.defaultCaptureDevice = VIDEO_CAPTURE_DEVICE_ID
g.acc.create(accCfg) } catch (e: Exception) { println(e) }
*Goal:- *To install the app-kotlin application on 2 different android
phones so that they can communicate with each other using different user
configurations.
Context:-
App Language:- Kotlin
*PJSIP **SDK Version: *pjproject-2.15.1
Platform: OS - MacOS, IDE - Android Studio Ladybug Feature Drop | 2024.2.2
Documentation refered:-
https://docs.pjsip.org/en/latest/get-started/android/kotlin-sip-client.html
Observations: The crash seems to indicate that the acc_id is either invalid
or not properly set up.
Questions:-
- I want to know the details of the warnings and errors I am getting.
- How should I set up the transport and account for 2 different android
phones which have the kotlin app installed on them to be able to call and
answer each other, basically steps to set up user accounts for SIP server? - Are there additional steps I should take to verify or initialize the
acc_id before passing it to pjsua_call_make_call?
Any guidance or suggestions to resolve this issue would be greatly
appreciated.
Thank you for your time and support.
Best regards,
Arsh K
