Instead of renting physical lines, connect your IP PBX to the carrier over the internet: channel-based pricing, unlimited extensions.
From 690 TRY/month
A SIP trunk lets the IP PBX inside your company send national and international calls to the carrier over the internet. It replaces old E1/PRI lines, and you can scale the number of channels up or down as needed.
Technical features
- Concurrent call channels: 10, 30, 60, 120 or custom
- Codec support: G.711 (alaw/ulaw), G.729, Opus; T.38 for fax
- TLS/SRTP encryption and IP-based authentication
- Multiple DIDs on the same trunk, such as 0212, 0216, 0312 and 0850 numbers
- Redundant registration (two separate SBCs) with automatic failover
Compatibility
It works with most Asterisk-based, enterprise IP PBX and contact centre systems; a compatibility test is run before installation. We size channel count together with an Erlang calculation, so you do not pay for spare capacity.
Pricing: 10 channels from 690 TRY a month; call minutes are billed per second after the call.

Frequently asked questions
Will my number change when I move to a cloud PBX?
No. We port geographic and 0850 numbers. We prepare the porting application, and the interruption during cut-over is usually under 30 minutes.
Does the phone work if the internet goes down?
When the primary connection fails, we define a failover rule that routes calls automatically to mobile phones or a backup number. For critical locations we recommend a second internet line (4G/5G backup).
How much internet speed is needed for voice quality?
Each concurrent call uses about 100 kbps of upstream bandwidth. For 30 concurrent calls you need 3 Mbps of dedicated upstream capacity, latency below 150 ms and packet loss below 1 percent.
Do I need to buy phones?
Not necessarily. The computer and mobile apps are free with the plan. If you want desk phones you can buy or rent them monthly; your existing SIP-compatible devices can often be reused.
How long are call recordings kept?
30 days, 90 days or 1 year depending on the plan. The period can be extended, and you can set the period your industry requires in the contract. Recordings are deleted automatically afterwards and are kept encrypted in data centres in Türkiye.
