Twilio SDK voip调用无效的Uri

Question

当我尝试通过twilio调用“名称”到“名称”时，出现此错误：

pjsua_call.c。对话框创建失败：无效的URI（PJSIP_EINVALIDURI）

当我遵循twilio教程时，我不知道为什么会发生此错误。 有什么线索吗？

这是我获得令牌的方式（应该可以）

 - (void)getTwilioToken{

        NSString *urlString = [NSString stringWithFormat:@"http://foo.herokuapp.com/token?client=%@", [[[Utils getUserCredential] componentsSeparatedByString:@"|"] objectAtIndex:1]];

        NSURL *url = [NSURL URLWithString:urlString];
        NSError *error = nil;
        NSString *token = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];

        if(token == nil){
            NSLog(@"Error retrieving token: %@", [error localizedDescription]);
        } else {
            _phone = [[TCDevice alloc] initWithCapabilityToken:token delegate:self];
        }

    }

这里是用来进行调用的代码：

-(IBAction)callResponder:(id)sender{

    NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];

    NSString *responderEmail = [[self.responders objectAtIndex:indexPath.row] email];
    NSDictionary *params = @{@"To": responderEmail};

    //check if we can make an outgoing call and attempt a connection
    NSNumber* hasOutgoing = [_phone.capabilities objectForKey:TCDeviceCapabilityOutgoingKey];
    if ( [hasOutgoing boolValue] == YES ){

        //Disconnect if we've already got a connection in progress
        if(_connection){
            [_connection disconnect];
        }
         _connection = [_phone connect:params delegate:self];
        [_connection retain];

    }

}

我本人也遇到了同样的问题。 问题与我如何设置Twilio令牌的权限（使用其Javascript API）有关：

var capability = new twilio.Capability(twilioAccountSid, twilioAuthToken);

capability.allowClientOutgoing(twilioAppSid);
capability.allowClientIncoming(); // this is the problematic line

在删除（显然不正确的）传入权限设置行之后，我的设备完美地完成了呼叫。
