我正在尝试编写一个简单的 SIP 代理来使用 PJSUA2 python swig 模块接收呼叫,但看不到这个 swig 模块是如何工作的。我有以下代码
import pjsua2 as pj
import time
class Endpoint(pj.Endpoint):
"""

"""
instance = None
def __init__(self):
pj.Endpoint.__init__(self)
Endpoint.instance = self

return Endpoint.instance.utilVerifyUri(uri) == pj.PJ_SUCCESS
def validateSipUri(uri):
return Endpoint.instance.utilVerifySipUri(uri) == pj.PJ_SUCCESS
# Call class
class Call(pj.Call):
"""

"""
def __init__(self, acc, peer_uri='', call_id=pj.PJSUA_INVALID_ID):
pj.Call.__init__(self, acc, call_id)
self.acc = acc
self.peerUri = peer_uri
self.connected = False
self.onhold = False
def onCallState(self, prm):
ci = self.getInfo()
self.connected = ci.state == pj.PJSIP_INV_STATE_CONFIRMED
def onCallMediaState(self, prm):

(mi.status == pj.PJSUA_CALL_MEDIA_ACTIVE or
mi.status == pj.PJSUA_CALL_MEDIA_REMOTE_HOLD):
m = self.getMedia(mi.index)
am = pj.AudioMedia.typecastFromMedia(m)
# connect ports
Endpoint.instance.audDevManager().getCaptureDevMedia().startTransmit(am)
am.startTransmit(Endpoint.instance.audDevManager().getPlaybackDevMedia())

c.answer(call_prm)
ci = c.getInfo()
if input(f"Accept call from {ci.remoteUri}?") == u'yes':
call_prm.statusCode = 200
c.answer(call_prm)
else:
c.hangup(call_prm)
def initalise_sip_stack():
ep_cfg = pj.EpConfig()
ep = Endpoint()
ep.libCreate()
ep.libInit(ep_cfg)
sip_tp_config = pj.TransportConfig()
sip_tp_config.port = 5060
ep.transportCreate(pj.PJSIP_TRANSPORT_UDP, sip_tp_config)
ep.libStart()
acfg = pj.AccountConfig()
acfg.idUri = "sip:[email protected]"
acfg.regConfig.registrarUri = "sip:172.20.1.8"
creds = pj.AuthCredInfo("digest", "*", "056004", 0, "somepass")

acc = Account()
acc.create(acfg)
return ep
if __name__ == "__main__":
endpoint = initalise_sip_stack()
time.sleep(600)
endpoint.libDestroy()
这个小客户端能够在我的星号服务器中注册,如您所见

不知道为什么它说
pjsua_acc.c ..No available account to handle Request msg INVITE/cseq=23923 (rdata0x7f5f6c001c48)
有什么想法吗?我的代码中哪一部分实现得不好?也许我应该将
initalise_sip_stack()
函数作为线程/进程处理?
非常感谢!
您是否收到错误消息:
“endpoint.cpp pjsua_transport_create(type, &tcfg, &tid) 错误:地址已在使用中”?
类型 须藤 netstat -nlp|grep 5060 如果此端口被阻止,这可能是您在创建帐户时遇到的问题。
