Graph API: create a PSTN call and invite a PSTN participant
yisroelperton: i don't know what exact was the cause: whether a SBC configuration or a Microsoft update. But it works now
relkniw, thank you for that update. Which API call did you use the peer-to-peer, or group call?
I'm using this page for reference:
https://learn.microsoft.com/en-us/graph/api/application-post-calls?view=graph-rest-1.0&tabs=http#example-9-create-peer-to-peer-pstn-call-with-service-hosted-media
yisroelperton peer-to-peer
- Hi, I have been using the peer-to-peer API call, and I have the bot making the call for a Team User and a PSTN number, and the call goes through for the Team user, but not for the PSTN number? Would you be able to know which example you were using in the documentation page?
Thank you.yisroelperton
This is my code for the MakeCall:var call = new Call
{
CallbackUri = Config.CurrentValue.CallBackUrl + ConfigurationConstants.CallbackSuffixCallEvents,
TenantId = Config.CurrentValue.ApplicationClient.TenantId,Source = new ParticipantInfo
{
Identity = new IdentitySet
{
// 05.11.2021 GW Handle PSTN calls
AdditionalData = new Dictionary<string, object>()
{
{"applicationInstance", new Identity()
{
DisplayName = Config.CurrentValue.ApplicationClient.DisplayName,
Id = Config.CurrentValue.ApplicationClient.BotUserObjectId
}
}
}},
Region = null,
LanguageId = null
},
Targets = new List<InvitationParticipantInfo>() { device },
RequestedModalities = new List<Modality> { Modality.Audio },
MediaConfig = new ServiceHostedMediaConfig { },
Direction = CallDirection.Outgoing,
};
var result = await graphAppClient.Communications.Calls
.Request(RequestHeader)
.AddResponseAsync(call);
