Currently there is a number of mobile phones available in the market, which support VoIP over WLANs and 3G Data networks. This allows for all the features of PBXes to be available on a single handset at home, at the office and on the go. Some advantages over the plain GSM telephony are:

• Unified CallerID. The PBXes CallerID will be shown to the called party, instead of the mobile phone's number.
• Unified Music on hold based on your PBXes account selection, instead of carrier announcements.
• Optional Time-based Routing, Ring Group participation, Privacy Manager for anonymous calls.
• Calls are billed as data on WLAN/3G plans, not as Mobile airtime.
• Avoid high roaming costs by using hotspots when staying in hotels or passing through airports.

Contractual Terms

PBXes provides you with the PBX itself. You decide which providers you subscribe and connect it to.

If you are going to use VoIP services outside private wireless networks, it's your responsibility to check the contractual terms with the mobile operator:

Often mobile phone operators forbid using VoIP in the contract's fine print. The European Union is already looking at whether blocks on VoIP service by Europe's mobile phone operators might breach competition laws.

The following plans are suitable for unlimited hotspot/3G usage:

• Germany: debitel Talk and Surf S

Add more!

Phones

Provisioning of these Mobile extensions need to follow certain configuration, particularly with regard to seamless switch-over from WLAN/3G to mobile networks:

Nokia

Installation of the following tools is recommended:

• Psiloc Connect if you intend to use WLAN and 3G alternately for VoIP.
• "VoIP settings" from Nokia to choose iLBC codec (compression reduces bandwidth usage from 1.2 MB per minute to 0.4 MB per minute).
• pbxes.org/m tracking client to publish position on your webcall page.

Android

Install SIP software from:

• sipdroid.org

To be able to listen to Voicemail in Emails change format in Source >> vm_general.inc to "format=wav|wav49".

PBXes

Add a SIP extension. After registering to it go on fine tuning:

Mobile Device Options

On paid accounts "handoff" may be enabled allowing calls to be held when loosing data connectivity. Handoff can be triggered manually by muting a call.

For Nokia mobiles you should de-activate the mailbox of your mobile number. If it can't be de-activated either set ConnectionCheck (will then register more often, up to 40 MB monthly) or FollowMe.

Call Forwarding (also in Extension)

Forward calls to your mobile number if unavailable or busy.

Only for Nokia phones also fork calls to your mobile (if you haven't used ConnectionCheck, see above).

Trunks

Numbers can be automatically converted from +xxx international format for IP calls by writing 011++|. into the trunk's rules (substitutes + by 011).

Outbound Routing (Nokia only)

With some versions of Nokia firmware you may have problems on outgoing calls like choppy ring back tone or delayed call establishment. In this case add rules with EarlyConnect option turned on (only available on paid accounts). To cover multiple extensions use wildcards, either of the form "20." (all numbers beginning with 20) or "20[123]" (201, 202, 203).
