Symptom / Need

The system's dialing pool automatically blocks due to excessive traffic or simultaneous calls to the same destination. Therefore, it is necessary to know the exact concurrency limits by time slot and telephone prefix to avoid operational blockages.

Context / Scenarios

Due to restrictions imposed by the telephone providers integrated into wolkvox, the system applies a block to dialing bags when the density of simultaneous calls to the same number or range of prefixes exceeds the configured rules.

Assessment slots: The conditions are strictly divided into two time blocks:
• Daytime Hours: From 7:00 a.m. to 10:00 p.m.
• Night Hours: From 10:00 PM to 7:00 AM.

Answer / Solution

Simultaneous Dialing Conditions

To avoid the suspension or blocking of dialing loops, the operation must self-regulate the concurrency of calls to the same destination according to the system conditions table:

1. Daytime Hours (7:00 – 22:00)
• Cell phones (Prefix 573) and General Limit: Maximum up to 15 simultaneous calls to the same number.
• Landlines Colombia (Area codes 571, 572, 574): Up to 50 simultaneous calls.
• Other destinations / General Limit: Maximum up to 10 simultaneous calls.
2. Night Hours (10:00 PM – 7:00 AM)
• Cell phones (Prefix 573): Capacity is increased to up to 50 simultaneous calls to the same number.
• Landlines Colombia (Area codes 571 to 575): Up to 50 simultaneous calls.
• Other destinations / General Limit: Maximum up to 10 simultaneous calls.

Recommendations

• Dialing database management: It is recommended to ensure that automatic dialing is distributed so that no more than 15 simultaneous calls are made to the same cell phone number during the day.
• You can validate your minutes package through the portal https://voice.wolkvox.com/user/ if you have your login credentials (package number and password). Otherwise, you cannot log in; however, after identity verification, a service desk analyst can share this information via encrypted email.
• If any failed or massive busy status occurs, check the alerts from the email voip-antispam@wolkvox.com which will be received in the email registered at the time of the creation of the bag, which can be verified by accessing the dashboard of the Voice wolkvox portal.
