C# get phone from SIP address

Question

I am using LyncClient library to create a widget and when a call comes in externally the remote participant sometimes comes up as 'sip:emailaddress@domain' if the contact is in the users outlook contacts.

Wondering if there is a way or library that allows me to open up the contact card for that email address and then get phone numbers if there are any.

Been pulling at my hair for a while now and can't figure it out. Any tips or experiences (good and bad) would be great! Let me know if you guys need more information.

Answer 1

I don't think that this is the email address.

SIP URI's has the same format as an email address: sip:username@sipdomain, so maybe Lync is just sending the peer sip address.

In this case you just have to grab the sub-string between "sip:" and "@" to get the caller id.

Another problem is that there are multiple ways for SIP to send the caller id. Maybe you should look for Asserted/Preferred identity (and Lync just extracts it from the SIP "Contact" header).

Answer 2

I made a program that gets the phone address out of a SIP URL. a SIP Url is basically in this format(Without quotes): "sip:username@domain"

    try
    {
        LyncClient lyncClient = LyncClient.GetClient();
        Contact contact;
        List<object> endPoints = new List<object>();

        Dictionary<string, string> phoneNumbers = new Dictionary<string, string>();
        contact = lyncClient.ContactManager.GetContactByUri("sip:[email protected]"); //PASS THE SIP ADDRESS HERE

        var telephoneNumber = (List<object>)contact.GetContactInformation(ContactInformationType.ContactEndpoints);
        //var contactName = contact.GetContactInformation(ContactInformationType.DisplayName).ToString();
        //var availability = contact.GetContactInformation(ContactInformationType.Activity).ToString();

        //foreach (object endPoint in telephoneNumber)
        //{
        //Console.WriteLine(((ContactEndpoint)endPoint).DisplayName + " " + ((ContactEndpoint)endPoint).Type.ToString());
        //}
        endPoints = telephoneNumber.Where<object>(N => ((ContactEndpoint)N).Type == ContactEndpointType.HomePhone || ((ContactEndpoint)N).Type == ContactEndpointType.MobilePhone || ((ContactEndpoint)N).Type == ContactEndpointType.OtherPhone || ((ContactEndpoint)N).Type == ContactEndpointType.WorkPhone).ToList<object>();
        foreach (var endPoint in endPoints)
        {
                    //Console.WriteLine(((ContactEndpoint)test).DisplayName.ToString());
            string numberType = Regex.Replace(((ContactEndpoint)endPoint).Type.ToString(), @"Phone", "");
            //string number = Regex.Replace(((ContactEndpoint)endPoint).DisplayName.ToString(), @"[^0-9]", "");
            string number = "";
            //Numbers only with dashes
            if (Regex.IsMatch(((ContactEndpoint)endPoint).DisplayName.ToString(), @"^\d{3}-\d{3}-\d{4}$"))
            {
                number = ((ContactEndpoint)endPoint).DisplayName.ToString();

                try
                {
                    phoneNumbers.Add(numberType, number);
                }
                catch
                {

                }
            }
            //Console.WriteLine(numberType + " " + number);
        }
        foreach (var entry in phoneNumbers)
        {
            //entry.Key is the PhoneType

            //entry.Value is the Phone Number
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("An error occurred: " + ex.Message);
    }
