My operation needs a dependable SIP trunk that can originate and terminate voice traffic to United Arab Emirates destinations while keeping KYC requirements to the absolute minimum—ideally none.

The trunk must comfortably handle tens of thousands of voice minutes per month, with enough concurrent channels to prevent congestion. Competitive per-minute rates, clean CLI presentation, and stable routing are critical. Please indicate whether you offer SIP registration or IP authentication, the codecs you support (G.711, G.729, etc.), and any fair-use or traffic restrictions. Deliverables • Active SIP credentials or IPs ready for testing • Current rate sheet and payment terms &bu...

We are currently working on our mobile application, GCM Dialer, which handles both SIM and SIP calls. We have successfully implemented the conference screen for the SIM and SIP merge option, but we are encountering an issue where voice is not being exchanged between all parties.

SMS integration is essential—I must be able to send and receive texts on the very same UAE number through the chosen app or an associated API. Acceptable solutions may involve: • Provisioning a UAE DID, SIP trunk or virtual number. • Full configuration on an Android softphone (e.g., Linkus, Zoiper, Grandstream Wave, etc.). • Demonstrated test call and SMS exchange showing local...
