Dograh

Dograh is the voice agent and Edesy is the carrier. For outbound calls, create an IP-allowlist termination trunk for Dograh's origin IP and add it as an outbound trunk in Dograh. For inbound calls, save Dograh's SIP endpoint as an Edesy destination and route your number to it. Set up either direction, or both.

How it works#

OUTBOUND  Dograh agent --SIP--> tk-<id>.trunk.edesy.in:5070 --> phone network
INBOUND   caller --> your Edesy number --SIP--> Dograh SIP endpoint --> your workflow answers

Before you start#

From Dograh Cloud, open Telephony configurations, find the managed SIP configuration, and expand SIP connectivity. Pick the region closest to your traffic (India for Indian numbers) and note:

• the inbound hostname and SIP port for that region
• the outbound origin IP to allowlist

Read these values from the panel each time; they differ by region and can change.

1. Create the trunk on Edesy#

Dograh Cloud sends calls identified by source IP, so use IP allowlist and enter the origin IP for your region.

curl -X POST https://voice-api.edesy.in/v1/trunks \
  -H "Authorization: Bearer sk_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Dograh production",
    "auth_mode": "ip_allowlist",
    "allowed_ips": ["<dograh-origin-ip>"],
    "max_concurrent_calls": 50
  }'

If you change region later, update the allowlist with PATCH/v1/trunks/:id.

2. Outbound: add the trunk in Dograh#

1. In the SIP configuration, under Outbound trunks, choose Add trunk.
2. Name: letters, digits and hyphens, such as edesy-in.
3. SIP domain: your trunk host, such as tk-1a2b3c4d.trunk.edesy.in.
4. Region: the same region as above. Save.
5. Add number: enter each Edesy number in E.164 (+91XXXXXXXXXX) and mark one as the default caller ID. Dograh needs a caller ID on every outbound call.

3. Inbound: route your number to Dograh#

In Dograh: in Phone numbers, set the number's Inbound workflow, and allowlist Edesy's signalling IP on your Dograh SIP domain.

In Edesy: save Dograh as a destination, then route the number to it.

# 1. Save the destination
curl -X POST https://voice-api.edesy.in/v1/sip-destinations \
  -H "Authorization: Bearer sk_YOUR_API_KEY" -H "Content-Type: application/json" \
  -d '{
    "name": "Dograh agent",
    "sip_uri": "sip:91XXXXXXXXXX@<your-domain>.<region-host>:<sip-port>",
    "transport": "auto"
  }'

# 2. Point the number at it
curl -X PATCH https://voice-api.edesy.in/v1/phone-numbers/NUMBER_ID/routing \
  -H "Authorization: Bearer sk_YOUR_API_KEY" -H "Content-Type: application/json" \
  -d '{
    "inbound_target_type": "sip",
    "inbound_sip_uri": "sip:91XXXXXXXXXX@<your-domain>.<region-host>:<sip-port>"
  }'

The URI is forwarded as saved, including a non-standard port.

Self-hosted Dograh#

Self-hosted Dograh connects to telephony through Asterisk ARI. Terminate the Edesy trunk on your Asterisk using the FreePBX 17 guide settings, set allow=ulaw on the Edesy endpoint, and follow Dograh's Asterisk ARI setup.

4. Test#

• Edesy outbound on its own: use the outbound test on the trunk page.
• Edesy to Dograh: click Test call on the Dograh agent destination.
• Then place a call from Dograh, and dial your number from a phone.
