# 80205: No Proxies For Service

Log Level: WARNING

## Description

Twilio returns this warning when you try to add a Participant to a Proxy Service that does not have any Proxy phone numbers configured. Proxy assigns phone numbers from the Service's phone number pool, and a Service must have numbers associated with it before Proxy can assign one to a Participant.

### Possible causes

* You have not added any Twilio phone numbers to the Service's Proxy phone number pool.
* The numbers you expected to use are associated with a different Proxy Service. A Twilio phone number can only be associated with one Proxy Service in the same account.
* You created the Service but did not finish configuring the number pool before creating Sessions or Participants. Proxy selects numbers from the Service pool when it creates Participants.

### Possible solutions

* Add one or more Twilio phone numbers to the Service before you create Participants.
* Confirm that the phone numbers are attached to this Service and not to another Proxy Service in your account.
* When you add numbers to the pool, choose numbers that support the Session `mode` you plan to use. Sessions can be `message-only`, `voice-only`, or `voice-and-message`, and number capabilities vary by country.
* If you use geographic matching, add numbers that match your participants' countries or required area codes so Proxy can assign compatible numbers after the pool is configured.
* If the same participant can appear in concurrent active Sessions, add enough numbers to the pool to support that concurrency. A participant cannot be assigned the same Proxy number in concurrent active Sessions.
