MobilePhone is logically connected to subscriber "master phone".

It can be both - extension or external number.

• external number ex. cellular phone - PABX establish calls via external trunk ports
• extension number ex. cordless phone (DECT) - PABX establish calls via internal ports

Depending on configuration, calls can be routed:

• in the same time to master phone and mobile phone
• only to mobile phone

Depending on call direction, MobilePhone functionality is following:

• incoming call answered on MobilePhone - it is enable to talk and transferring call to any another PABX subscriber
• call from MobilePhone to PABX - privileges are the same like for "master phone"
• in both directions - after establishing call to MobilePhone, "master phone" is busy

Configuration, privileges, limitations

• After rejecting call from any phone ("master phone"/MobilePhone) second one also stop ringing.
• After answering call on MobilePhone, until finishing this call, "master phone" is busy.
• During transferring call from MobilePhone to any PABX extension number, "master phone" is busy.

MobilePhone switching on

Switching on and off MobilePhone service can be done from "master phone" or calling from MobilePhone to DISA if it is defined in PABX.

#77 0 - switching off call forwarding to MobilePhone
#77 1 - switching on call forwarding to MobilePhone when no answer or while DND
#77 2 - switching on call forwarding to MobilePhone only when no answer

It means, that after switching on MobilePhone service, if any other call forwarding is active, it is deactivated. MobilePhone service switching off, activates defined call forwarding once more.
Otherwise, switching on I'm there service (#57), deactivates MobilePhone service.

Trasfer call from MobilePhone back to the PABX

This service is realized if MobilePhone is external number (ex. cellular phone) and incoming call to "master phone" was routed to MobilePhone. After answering this call, if you want to transfer this call to another PABX subscriber, following activities should be done:

• Inform caller to doesn't hang off the phone.
• Finish this call. During 15 seconds in caller handset there is a silence and than single beeps can be hear.
• From MobilePhone dial PABX subscriber number, from this time caller hears message "Please wait for connection". To enable this service, must exists direct external number to subscriber whom you want to transfer call (In DDI or MSN numbering plan) or it is possible to dial any number and during DISA announcement it is possible to dial extension number.
  • Transfer with announcement: after answering call and announcement disconnect yourself - waiting caller stay connected.
  • Transfer without announcement: after hearing ringing tone disconnect yourself - waiting caller is transfered and hears ringing tone of extension number dialed from MobilePhone.

Transfer to busy phone

If during transferring call to another extension number, there is busy signal hears, transferring call is realized according different rules, than described above.
Calling from standard phone via incoming trunks connected to PABX, after hearing busy signal you don't know what is a reason of busyness. Reason of busyness can be following:

• subscriber to whom call should be transferred is busy
• subscriber is free but all incoming trunk are busy
• subscriber to whom call should be transferred activated DND service

Due to mentioned above notices some changes were introduced in incoming calls maintenance for MobilePhone service. Depending on situation, when you transfer call system behavior can be as follows:

1. If you transfer call from MobilePhone to any PABX extension number dialing via DISA announcement and you hear busy signal, it means all external lines in PABX are busy. If there is possibility to dial another number to connect with PABX, you can try once more. For PABX it is not important what number was dialed to transfer call. Only thing important is CLIP receiving for incoming trunks assigned to these numbers - it is necessarily to enable PABX to detect MobilePhone number. Maximal time to transfer call is limited to 45 seconds. If during this time there will be no call from MobilePhone, waiting connected call will be disconnected and caller will hear busy signal.

2. If you transfer call from MobilePhone to any PABX extension number dialing external number routed directly to this extension number (extaernal trunks connected to PABX are ISDN type) and you hear busy signal, it means all external lines in PABX are busy or dialed subscriber activated DND service. Then transfer should be done to another extension number. Otherwise waited caller will be disconnected after 45 seconds.

3. If you transfer call from MobilePhone dialing via DISA announcement and during this announcement dialing extension number After dialing extension number busy signal can be hear you can:

1) Disconnect yourself. Your interlocutor will be set in a queue to busy subscriber:

a) If busy subscriber uses system phone CTS-202 or CTS-102 he/she can see information about waiting call, including number of waiting person on phone display. Additionally knocking signal can be/she can hear in phone handset.

b) If busy subscriber uses analogue phone be/she can hear knocking signal in phone handset.

2) Press on your phone, after it PABX dialing signal can be hear again, to transfer call to another extension number, dial this number.

3) Press on your phone twice. After first press, PABX dialing signal can be hear as described above, after second press connection with waiting caller will be established. You can inform this person about no possibility of transfer call and finish call, or start transferring procedure again.

4. If you transfer call from MobilePhone to any PABX extension number dialing external number routed directly to this extension number (extaernal trunks connected to PABX are ISDN type), even if this extension number is busy, signal inside first 10 seconds (two signals) is similar as ringing signal. If you disconnect during this time, means transferring call without checking is extension number free or busy - in this situation call is automatically set into queue. If extension number you want to transfer to is busy and you not disconnect yourself during first 10 seconds, you hear busy signal. You can start transferring procedure from the beginning dialing another subscriber or the same extension number once more but you must disconnect yourself inside first 10 seconds to automatically set call into queue. You can also don't do anything - after 45 seconds PABX automatically tries to connect waiting call to the same extension number and automatically set this call into waiting queue.

Attention: Waiting call will be disconnected if waiting time for answering by dialed extension number will be exceeded. If call is transferred by MobilePhone, return to the call doesn't work if target subscriber doesn't aswer.

Call signaling

Calls routed to mobile phone as a result of MobilePhone service operating are not different than others calls in PABX. Caller presentation cannot be transferred to mobile phone. PABX admin can configure it to present incoming calls routed to mobile phone with another number, but usually it is concerned with higher call fees.
Additional functionality, if GSM card is installed in PABX, is reporting to MobilePhone user about:

• Nieodebranym połączeniu skierowanym na MobilePhone. Użytkownik otrzymuje SMS-a o przykładowej treści:

MobilePhone

Nieodebrane +48226509900 

Warszawa

• Jeśli w czasie kiedy połączenie przychodzące było skierowane funkcją MobilePhone na telefon komórkowy, który był zajęty inną rozmową otrzymamy SMS-a o przykładowej treści:
  

MobilePhone

Zajęte +48226509900 

Warszawa

• Jeśli połączenie przychodzące na MobilePhone zostanie odrzucone na telefonie komórkowym otrzymamy SMS-a o takiej samej treści jak w przypadku zajętości czyli np:
  

MobilePhone

Zajęte +48226509900

Using MobilePhone as backup phone

Jeśli jako numer MobilePhone zostanie zadeklarowany inny numer wewnętrzny centrali ( np. telefon systemu DECT) wówczas uzyskamy rozbudowany system telefonu równoległego który pozwala między innymi na:

• Logiczne równoległe połączenie telefonu systemowego CTS-202 lub CTS-102 z telefonem analogowym. Ze względu na różne sposoby porozumiewania się z centralą fizyczne równoległe połączenie nie jest możliwe.
• Możliwa jest prezentacja jednym numerem ( zarówno miejskim jak i wewnętrznym) dla obu telefonów.
• w czasie gdy z dowolnego telefonu prowadzona jest rozmowa drugi jest również zajęty
• Użycie MobilePhone "przykrywa" przekierowania abonenta, bez ich wyłączania. Dezaktywacja MobilePhone ponownie je przywraca.
  

Przykład:
Abonent chce używać w czasie godzin pracy telefonu bezprzewodowego, a po godzinach jego rozmowy powinny być przekierowane na komórkę. Jeśli jako MobilePhone zostanie wpisany telefon bezprzewodowy, i wpisane zostanie przekierowanie połączeń na komórkę to w czasie gdy MobilePhone jest włączony przekierowanie nie działa, a wyłączenie MobilePhone powoduje automatyczne uruchomienie przekierowania. Nie ma potrzeby każdorazowej zmiany czy wpisywania numeru i aktywowania usługi.
